September 21, 2025 | Editor: Adam Levine
13
Enterprise group chat apps that enable instant messaging, file sharing, video conferencing, and task management.
1
Microsoft Teams is the chat-based workspace in Office 365 that integrates all the people, content, and tools your team needs to be more engaged and effective. Supports video meetings with up to 1,000 participants.
2
Slack brings all your communication together in one place. It's real-time messaging, archiving and search for modern teams. Create open channels for the projects, groups and topics that the whole team shares. Slack searches whole conversations, not just individual messages, so you can find what you’re looking for no matter who said what or when they said it.
3
Discord is a VoIP and instant messaging social platform. Users have the ability to communicate with voice calls, video calls, text messaging, media and files in private chats or as part of communities called "servers".
4
Google Chat is a communication service developed for teams and business environments, but also available for general consumers as chat in GMail and mobile app.
5
Open source, on-premises, Slack-alternative. Like Slack, you can send messages and files across channels, get notifications on unreads and mentions, and search history–all from your PC or smartphone.
6
Plan, share, & organize work in real-time. Glip organizes your team’s work while you chat with your co-workers, and makes your conversations productive. All your projects, meetings and files live in the stream, so everyone is in the loop on what’s happening.

Hashtags, cashtags and mentions - never miss an important message with personalized filters. Secure access to your conversations on your desktop or on your iPhone.
12
With Chatter, it’s easy to work together and know everything that’s happening in your company. Updates on people, groups, documents, and your application data come straight to you in real-time feeds. It's better than alternative solutions for Salesforce users.
13
Fleep is chat for teams and businesses. Your files and messages. Always in sync. On all devices. Team communication is now a simple, common-sense thing. Fishing for someone’s wise words in an ocean of chat? Instead, pin important messages to the side so everyone can see and edit them. Task lists, meeting notes, important links, etc. As with messages, trawling for files in a long conversation wastes your life. In Fleep, all photos and documents have a nice clean drawer on the side tab, next to the conversation flow.
14
Take your conversations with you, wherever you go. Stay connected to your colleagues and don't miss a discussion anymore - the ChatGrape mobile apps for iOS and Android will keep you updated and let you join the conversation easily, no matter where you are.

Important news about Team Messaging platforms
2025. Microsoft to cut Teams from Office 365 to avoid EU sanctions
Microsoft has decided to spin off the corporate messenger Teams from the Office 365 suite to avoid an EU fine of 10% of its global annual turnover. In addition, prices for Teams plans without video conferencing will be reduced and compatibility with competing software will be improved. The antitrust investigation against Microsoft began after a complaint from Teams competitor Slack in July 2020. The European Commission then pointed out that the integration of Microsoft's IT platforms creates an unfair advantage over other market players. In 2024, the European Commission accused Microsoft of violating antitrust laws due to the fact that the IT company sold the Teams messenger in Office 365 and Microsoft 365 packages for several years.
2025. Slack adds AI to search, transcripts and chat summary
Enterprise messaging app Slack has expanded its search capabilities with AI features, including voice message transcripts and chat summaries, as well as short AI summaries of channels and discussions. Using AI, Slack now lets you search across chat channels, as well as connected apps (like Google Drive, Salesforce and Microsoft Teams). Huddles (voice and video chat features) also includes call transcripts and summaries. The AI automatically highlights key phrases in conversations. You can also get a short summary of another user’s profile, showing their role and recent work. Or get a summary of all the messages in which you are mentioned.
2023. Microsoft’s AI-powered Designer tool comes to Teams
Microsoft is introducing its AI-driven art creation tool, Designer, to the free version of Teams. Users of Microsoft Teams can now utilize Designer, an app similar to Canva, to generate various designs for presentations, posters, digital postcards, and other purposes. These designs can be shared on social media platforms and other channels. Designer can generate designs based on text prompts or uploaded images by leveraging DALL-E 2, OpenAI's text-to-image AI. The tool offers options for customization and personalization through drop-down menus and text boxes. Designer is accessible through the web, Microsoft's Edge browser via the sidebar, and now within the free version of Teams. The announcement of Designer was initially made in October, and new features such as caption generation and animated visuals were added in April. Microsoft has also promised additional advanced editing features in the future.
