Which col­lab­o­ra­tion tool fits your needs?

Col­lab­o­ra­tion tools are digital ap­pli­ca­tions that make location-in­de­pen­dent col­lab­o­ra­tion and com­mu­ni­ca­tion within teams easier. They enable joint work on documents, real-time in­for­ma­tion sharing, and the or­ga­ni­za­tion of tasks and projects. Different tools stand out with varying feature sets.

What are col­lab­o­ra­tion tools?

A col­lab­o­ra­tion tool or col­lab­o­ra­tion software offers various functions for managing projects and teamwork. The purpose of such a software solution is to optimize workflows, which is why the in­di­vid­ual tools are suited for areas like planning, or­ga­ni­za­tion, or analysis. A tool can dis­tin­guish itself with features such as:

• Mind mapping: Many tools support teams in brain­storm­ing and creative col­lab­o­ra­tion. Tools for creating mind maps as well as other brain­storm­ing features encourage project par­tic­i­pants to share their own ideas and actively shape the project.
• File sharing: One of the core prin­ci­ples of col­lab­o­ra­tion software is that users can share spread­sheets, documents, and other data with col­leagues. Many tools offer a central storage platform and the option to define in­di­vid­ual access rights.
• Real-time com­mu­ni­ca­tion: Col­lab­o­ra­tion tools often include various functions for com­mu­ni­cat­ing in real time. Many built-in ap­pli­ca­tions rely on es­tab­lished com­mu­ni­ca­tion methods such as video calls, instant messaging, and email or offer in­te­gra­tions with common programs like Outlook.
• Shared calendar: Whether you’ve scheduled a team meeting, have important business calls coming up, or set a deadline: Emails, calls, or chat messages are good ways to inform people about upcoming events – but they’re often quickly forgotten. That’s why col­lab­o­ra­tion tools provide calendar features so all relevant dates can be shared and accessed at any time.
• Man­age­ment features: Good col­lab­o­ra­tion software also ensures that project and team leaders can optimally plan and oversee different workflows. Com­po­nents are available to allocate and organize existing resources ef­fi­cient­ly. In addition, many tools offer solutions to document and analyze workflows and progress.

Why it pays to use col­lab­o­ra­tion software

Of course, you don’t nec­es­sar­i­ly need col­lab­o­ra­tion software to organize projects and optimize workflows. A small team working in the same office can often co­or­di­nate without specific tools or with just a few in­di­vid­ual ap­pli­ca­tions. However, with a growing number of employees and projects and par­tic­i­pants who are not connected to the company network, the value of such software for op­ti­miz­ing workflows increases sig­nif­i­cant­ly:

• In­creas­ing com­plex­i­ty: Things get confusing when multiple teams and deadlines need to be co­or­di­nat­ed.
• Ef­fi­cien­cy gains: Status updates and agree­ments can be handled centrally and save time.
• Cost savings: Less manual work and more time for strategic tasks.
• Central file sharing: File sharing works in­de­pen­dent­ly of the company network.
• Easy partner in­te­gra­tion: External parties can be seam­less­ly in­te­grat­ed into processes.

What col­lab­o­ra­tion tools are available? 9 tools in detail

Finding the right software for workflow op­ti­miza­tion is often harder than it seems at first glance. This is mainly due to two factors: First, the different solutions vary con­sid­er­ably in terms of scope and costs (ranging from expensive en­ter­prise to free freemium or open-source solutions).

Some ap­pli­ca­tions offer a wide range of col­lab­o­ra­tion features, while others are spe­cial­ized in certain functions. It is also important to dis­tin­guish between locally hosted solutions and provider-hosted online ap­pli­ca­tions (cloud or SaaS). While the former have ad­van­tages in terms of security, the latter are stronger in terms of remote access.

Microsoft 365

Microsoft is primarily known for its Office ap­pli­ca­tions alongside Windows. In 2011, the company brought Microsoft 365 to the cloud as web ap­pli­ca­tions, paving the way to turn Word and others into col­lab­o­ra­tion software. Instead of pur­chas­ing the software package, Microsoft 365 allows you to subscribe to the programs and access them via a web browser.

A key advantage: Microsoft 365 not only offers a wide range of in­te­grat­ed ap­pli­ca­tions but also, for some time now, AI features under the name Copilot. These AI-powered tools help, for example, in Word with drafting texts, in Excel with creating complex formulas, or in Outlook with au­to­mat­i­cal­ly sorting and re­spond­ing to emails – all directly within the familiar ap­pli­ca­tions.

Since Microsoft 365 consists of various programs, the pos­si­bil­i­ties for col­lab­o­ra­tion are equally diverse. With Outlook (and Exchange), for example, you can share calendars within the company. Word, Excel, and Pow­er­Point in the cloud allow multiple users to work on files si­mul­ta­ne­ous­ly – no more cum­ber­some email at­tach­ments. Microsoft Teams is col­lab­o­ra­tion software that primarily enables com­mu­ni­ca­tion between employees.

Few other solutions offer such a range of options. While many other col­lab­o­ra­tion tools can be expanded with in­te­gra­tions and ad­di­tion­al apps, Microsoft 365 has all essential tools built in.

Col­lab­o­ra­tion ap­pli­ca­tions in Microsoft 365:

• Word: Word pro­cess­ing with multiple users
• Excel: Spread­sheets with multiple users
• Pow­er­Point: Create pre­sen­ta­tions with multiple users
• Outlook: Share ap­point­ments, calendars, and tasks with team members
• Teams: Com­mu­ni­cate with col­leagues
• Access: Create databases with multiple users
• OneNote: Share notes with others
• OneDrive: Shared cloud storage

Google Workspace

While Google is still best known as a search engine provider, millions of people worldwide also use the company’s other services. Some of these are bundled under Google Workspace. This is a software suite for office work and multiple col­lab­o­ra­tion tools. Most people are familiar with Gmail, Google’s free email service; Google Docs for creating documents; and Google Drive, the provider’s cloud storage. Many of these ap­pli­ca­tions are available for free to private users with a Google account. However, busi­ness­es can also opt for an upgraded version with ad­di­tion­al services: pro­fes­sion­al email addresses, more storage, and 24/7 support.

The ap­pli­ca­tions are designed as Software-as-a-Service or cloud computing: The software doesn’t run on the users’ devices but is accessed via a web interface. Since all data is stored in the cloud, users can easily access it together. Calendars can be shared, documents can be edited col­lab­o­ra­tive­ly, and meetings can be held online.

Col­lab­o­ra­tion features in Google Workspace:

• Com­mu­ni­ca­tion: With the Gmail email service, Google Chat (for internal chatrooms), and Google Meet (for video con­fer­enc­ing), team members can com­mu­ni­cate with each other.
• Task man­age­ment: Calendar and note-taking apps allow tasks to be assigned and deadlines to be set.
• Creation: In addition to the well-known tools for creating documents (Docs, Sheets, Forms, and Slides), Google Workspace also allows you to col­lab­o­ra­tive­ly work on websites and custom-built apps.
• Storage: Along with the Drive cloud storage, Google also offers Vault, an archive solution for business customers.
• Ad­min­is­tra­tion: To give companies full control over Google Workspace, the Admin app lets you manage users and assign per­mis­sions.
• AI as­sis­tance: Google also offers users the general AI assistant Gemini, which can summarize content in Docs and Sheets, as well as the research AI Note­bookLM.

Asana

In 2011, Facebook co-founder Dustin Moskovitz and pro­gram­mer Justin Rosen­stein launched the col­lab­o­ra­tion software Asana. Both had pre­vi­ous­ly worked on in-house workflow op­ti­miza­tion solutions for the social media giant, where the idea arose to develop a stand­alone tool. The SaaS web ap­pli­ca­tion, hosted on the company’s own servers, focuses on managing projects and tasks without the need for an ad­di­tion­al com­mu­ni­ca­tion platform. In addition to the web ap­pli­ca­tion, which can be accessed via any common web browser, there are also apps for iOS and Android, allowing Asana to be used on mobile devices. The Personal version of the tool is free, but unlike the paid versions “Starter,” “Advanced,” and “En­ter­prise,” it offers only a limited feature set.

With Asana, you can assign any number of teams their own workspace. Within such a digital workspace, you can manage any number of projects by creating, taking on, and pro­cess­ing tasks. You can, for example, define deadlines, add tags to filter tasks, or attach local files and documents from Dropbox, OneDrive, Box, and Google Drive. A dashboard provides an overview of various projects and tasks, sortable by alphabet, deadline, or task status.

Other features of the col­lab­o­ra­tion tool include:

• Dedicated team calendar
• Project chat (Con­ver­sa­tions)
• Messaging system (Inbox) with archive
• Undo function
• Task syn­chro­niza­tion with external calendar software
• Print and export functions (CSV) for projects and tasks
• Automatic task pri­or­i­ti­za­tion and status reports through gen­er­a­tive AI

The free version allows you to set up projects for up to 10 people. If you need to manage larger teams, you should upgrade to the Premium editions. These also include pre­de­fined templates that let you create new projects with a single click. Ad­di­tion­al­ly, the paid plans provide advanced search and reporting features for even smoother workflows, as well as access to spe­cial­ized admin features for better project and user control. The En­ter­prise version also offers exclusive support and the option to enforce SAML-based login (Security Assertion Markup Language) for all users.

Trello

The American company Fog Creek Software released its col­lab­o­ra­tion tool Trello in September 2011 after about a year of de­vel­op­ment. The tool, now owned by the software company Atlassian, is available as a platform-in­de­pen­dent web ap­pli­ca­tion and a mobile app for iOS and Android, enabling task co­or­di­na­tion through Trello’s clear, easy-to-use boards. Ad­di­tion­al col­lab­o­ra­tion features such as calendars or in­te­gra­tions with cloud ap­pli­ca­tions can be added via so-called Power-Ups. AI support is also in­te­grat­ed but is only available to users of the “Standard,” “Premium,” and “En­ter­prise” plans.

When you create a new board in Trello, you have three sharing options: In private mode, only manually added users can view and make changes to the board. Team boards, on the other hand, are au­to­mat­i­cal­ly visible to all members of the project team. If you choose public sharing, anyone with the cor­re­spond­ing link can view the board online. Editing, however, is only possible in both cases if you have been added by the project manager. Task dis­tri­b­u­tion works via so-called cards, which can be sorted into different lists to indicate the pro­cess­ing status. For designing in­di­vid­ual tasks (cards), the following options are available:

• Assign members
• Add labels (color and optional pattern)
• Add check­lists with unlimited items
• Comment
• Set due dates for tasks
• Attach links or files (PC, Trello, Google Drive, Dropbox, Box, OneDrive)
• View activity log
• Move to another list as status changes

By default, files from your computer can be up to 10 MB. At­tach­ments up to 250 MB are available from the “Standard” plan onward. Paid plans also let you control who can create public or private boards and remove former members with one click. Premium support via email ensures a response within 24 hours for technical issues and questions.

Slack

Since 2014, the col­lab­o­ra­tion tool Slack has sim­pli­fied com­mu­ni­ca­tion in companies and agencies. The software also ensures that users always have access to all ap­pli­ca­tions, services, and resources they need for their daily work. Slack is already used by over 40 million active users from more than 150 countries and over 750,000 companies every day. The web-based ap­pli­ca­tion, also available as an app for iOS, Android, Windows, macOS, and Linux, can be used free of charge or with a monthly fee (“Pro,” “Business+,” and “En­ter­prise+”), with paid plans offering more features.

The main focus of Slack is to provide users with the best possible com­mu­ni­ca­tion platform. To this end, you can create unlimited channels, which es­sen­tial­ly function like chat rooms. When setting up such a channel, you can choose to either make it ac­ces­si­ble to all invited employees or manually control who can join (Private Channel). Ad­di­tion­al­ly, all members reg­is­tered in the col­lab­o­ra­tion tool can com­mu­ni­cate via direct messages with one another. It’s not only possible to send regular text messages, but also to share files (PC, Google Drive), share documents (Google Docs), or present code snippets (HTML, CSS, C++, PHP, and more).

The second core feature of Slack is the in­te­gra­tion of third-party ap­pli­ca­tions. In­ter­faces already exist for the following web services, among others:

• File man­age­ment: Google Drive, Dropbox, Microsoft OneDrive, Box
• Com­mu­ni­ca­tion: Google Hangouts, RSS, MailChimp
• De­vel­op­ment: GitHub, IFTTT, Zapier, Jira Cloud, Nagios
• Marketing: Statsbot, GrowthBot, Drift, Mention, Reveal
• Pro­duc­tiv­i­ty: Trello, Google Calendar, Asana, Simple Poll
• Social & Fun: GIPHY, Twitter, Bitmoji, Meme Bot
• Design: InVision App, Zeplin, Lu­cid­chart, Re­al­time­Board

The more channels you create for project man­age­ment, the harder it becomes to maintain an overview – but Slack’s high-quality search feature makes it easy to find con­ver­sa­tions and files anytime. The free version only accesses the last 90 days of messages, and third-party in­te­gra­tions are limited to ten. These re­stric­tions are removed in the “Pro plan”, which also allows guest access and OAuth (Open Au­then­ti­ca­tion) features. The “Business+” version promises 24/7 support with a maximum response time of four hours. The En­ter­prise version offers even more features; prices are available upon request.

Slack is also in­creas­ing­ly relying on AI-powered, automated workflows that summarize messages, detect sen­ti­ments, and display con­tex­tu­al­ly relevant content from other apps.

Basecamp

In 2004, the Chicago-based company 37signals (now Basecamp) released its col­lab­o­ra­tion software Basecamp, which has since been sold over three million times. The tool organizes both internal company com­mu­ni­ca­tion and project work as well as col­lab­o­ra­tion with business partners, bringing together all your teams, projects, and work­groups on a single platform. Access to Basecamp is available either through common web browsers such as Google Chrome, Safari, Microsoft Edge, or Mozilla Firefox, or via the desktop ap­pli­ca­tion for Windows and macOS. Thanks to apps for iOS and Android, mobile users can also take advantage of Basecamp’s advanced col­lab­o­ra­tion features.

The Basecamp interface, which may seem over­whelm­ing at first, is divided into three main areas: The “Head­quar­ters” (HQ) section is for company-wide an­nounce­ments, general in­for­ma­tion, and files available to everyone – intended for company lead­er­ship. Under “Teams,” you can create de­part­ment-specific platforms for com­mu­ni­ca­tion and planning. The “Projects” section displays the channels for in­di­vid­ual work projects and their par­tic­i­pants. Re­gard­less of the section, six core features are always available:

• Chatroom: In­di­vid­ual chat room for each group (formerly called “Campfire”)
• Message board: For an­nounce­ments and status updates
• To-dos: To-do lists with deadlines for key tasks
• Schedule: Calendar in­te­gra­tion with Google Cal, iCal, or Outlook
• Automatic check-ins: Automated status questions (daily, weekly, or monthly)
• Docs & files: Central file storage for documents and links to Google Docs, organized via folders

Basecamp is free for a single project. To manage multiple projects, you need to upgrade to the paid “Basecamp Plus” or “Basecamp Pro Unlimited” plans. Both offer ad­di­tion­al features like increased storage or better support. A unique aspect is that pricing for the Pro Unlimited plan is in­de­pen­dent of the number of users.

Wrike

The col­lab­o­ra­tion tool Wrike is the core product of the company of the same name, founded in Cal­i­for­nia in 2006 and multiple award winner in project man­age­ment, work man­age­ment, and business growth. Since March 2021, Wrike has been part of the U.S. software company Citrix.

With features that regulate com­mu­ni­ca­tion, trans­paren­cy, and ac­count­abil­i­ty in projects, the software is aimed at marketing, creative, project man­age­ment, and product de­vel­op­ment teams, among others. In addition to a free edition with limited features, Wrike offers various tailored solutions like “Team” or “Business” with different focuses. The ap­pli­ca­tion can be accessed via the web or desktop apps (Windows, macOS) and mobile apps (iOS, Android).

Every project you manage with Wrike can be divided into any number of sub-tasks. In­di­vid­ual tasks can be organized using folders and schedules, which can be viewed and adjusted in the timeline view. This way, you can stay informed about the progress and con­tri­bu­tions of all team members at any time. The live activity stream, version control, and the shared file storage (starting at 2 gigabytes), where relevant documents can be stored and linked, also help with this. To avoid having to create every task from scratch, the col­lab­o­ra­tion tool offers a practical copy function that lets you easily duplicate recurring tasks or even entire projects. Like some other solutions, the Wrike board can also be expanded through in­te­gra­tions such as the following:

• File sharing: Google Drive, Box, Dropbox, Microsoft OneDrive
• De­vel­op­ment: Jira, GitHub
• Analytics: Tableau
• Chat/Messaging: Slack, Microsoft Teams
• Single Sign-On: SAML in­te­gra­tion, Okta, Microsoft in­te­gra­tion

For those with higher demands on col­lab­o­ra­tion software, the “Team” version is the minimum rec­om­mend­ed option. It includes 5 GB of storage, access to gen­er­a­tive AI, shareable dash­boards, and an unlimited number of free viewers. Starting with the “Business” plan, you get 15 GB of storage per user, plus ad­di­tion­al features like resource man­age­ment, user groups and per­mis­sions, report templates, and the ability to customize your workspace. If you choose to test Wrike, you can freely choose from the available plans and confirm your choice after the trial period or al­ter­na­tive­ly select a different sub­scrip­tion if you decide to make a purchase.

Spike

Not a full col­lab­o­ra­tion tool, but a great com­ple­ment for any team – whether in large cor­po­ra­tions or small projects: Spike rev­o­lu­tion­izes the way we handle email. Instead of dealing with long email threads, un­nec­es­sary subject lines, and ir­rel­e­vant sig­na­tures, Spike presents emails as if they were chat messages. This AI-powered software displays messages in a clear dialog format, omitting every­thing unrelated to the actual message content. Upon request, even suggested replies are generated. Unlike tra­di­tion­al email com­mu­ni­ca­tion, Spike works in real time.

In addition to this in­no­v­a­tive display format, Spike also impresses with other features: For example, it allows you to make VoIP or video calls directly within the ap­pli­ca­tion. Users can also manage a calendar with the software and easily share files with one another. Messages can be encrypted if desired.

These functions make Spike a great add-on to other col­lab­o­ra­tion software:

• Email com­mu­ni­ca­tion in chat format
• Voice and video calls
• File sharing
• Calendar man­age­ment

To use Spike, simply add your email account in­for­ma­tion. For personal users, the ap­pli­ca­tion is free up to a certain limit. A monthly sub­scrip­tion (free for students) includes extra storage (from 5 GB) and priority support. Pro­fes­sion­al teams pay a monthly fee. Spike is available for Android, iOS, macOS, Windows, and as a web app.

Notion

Notion is not a classic col­lab­o­ra­tion tool either. Rather, it is internal com­mu­ni­ca­tion software known for its modular structure and high flex­i­bil­i­ty. It combines functions for note-taking, task man­age­ment, databases, calendars, and wikis into a single interface. Teams can use it to create central knowledge bases, organize project-related content, and manage tasks visually. Instead of relying on fixed templates, Notion allows users to design pages with cus­tomiz­able blocks such as text, tables, to-do lists, Kanban boards, calendars, or embedded media. It is es­pe­cial­ly popular for building and main­tain­ing internal knowledge databases.

Col­lab­o­ra­tion in Notion happens in real time: Changes are instantly visible to everyone, and comments can be attached directly to content. A version history tracks all edits. The in­te­grat­ed Notion AI can summarize, rewrite, translate, or structure texts, extract tasks from meeting notes, or convert content into tables. With numerous templates and in­te­gra­tions (like Slack, Google Drive, or GitHub), on­board­ing is easy, and workflows connect seam­less­ly.

Notion is available via web browser, desktop, and mobile apps, sup­port­ing flexible work. A free plan is available for small teams or in­di­vid­u­als, while the “Plus,” “Business,” and “En­ter­prise” plans offer advanced rights, analytics, and better support. The interface is min­i­mal­ist yet powerful, and despite its many features, it remains intuitive. Data is stored on U.S. servers.
