Congrats on the launch @katja_danilina !

Something on the roadmap: Mantle already has a pretty strong list of integrations. Are you planning to add HubSpot or Zendesk so agents can also help with sales and customer support workflows?

Does Mantle keep a persistent shared context across sessions — so the AI understands decisions the team made in previous conversations — or does each new session start fresh? That long-term memory layer feels like the key differentiator for async teams.

Does Mantle keep a persistent shared context across sessions — so the AI understands decisions the team made in previous conversations — or does each new session start fresh? That long-term memory layer seems like the thing that would make it genuinely more useful than just adding AI to a Slack channel.

Love the "@ the model in the same channel as your teammates" framing, that's the part Slack-with-a-bot-bolted-on always got wrong. Curious how you're handling context isolation when multiple agents are working on tasks in parallel in the same channel? Does each agent get its own thread, or do they share the channel history?

One underrated benefit here is institutional memory . Shared AI conversations are way more valuable than knowledge trapped in private chats.

I’ve been jumping between Claude and ChatGPT tabs for months depending on what I’m working on. Never really found a smooth way to keep both in one workflow.

Mantle looks interesting for that. Curious to see if having one workspace actually solves it.

Hey Katja! You're awesome. AI and team chat integrated is a game changer cause it comes to upgrade teamwork. I'm sure many founders gonna love this!

Shared AI context across a team is way better than everyone running isolated prompts. Mantle Chat looks like it could cut down a lot of duplicated work in growing teams. We've been building in the customer success for ops-heavy SaaS teams space at RetainSure, and Mantle Chat touches on something we think about a lot. How does it handle context isolation between different projects?

Shared AI threads are the right move. The problem with private AI sessions is that your team's best prompts and outputs never get socialized. At RetainSure we've got CS reps doing similar AI-assisted tasks in silos, so we lose institutional knowledge constantly. Do you have any versioning or replay for how an AI-assisted decision was reached in a shared channel?

Congrats on launching! Wishing you a smooth start, happy users, and lots of success.

the positioning against private AI chats is the interesting angle here. the actual problem is that when everyone's prompting Claude or GPT separately, institutional knowledge just evaporates. nobody knows what their teammate already figured out. if Mantle actually solves that it's solving something real

Congrats on the launch! This looks really promising! Been looking for something like this! @katja_danilina

Congrats on the launch! The idea of combining chat, agents, and tools in one shared workspace feels very practical for real team workflows. You can also say that the @ plus agent approach inside channels is important in reducing context switching.

Right now we're paying for 4 different AI tools across a 6 person team. No shared history, no shared context, and the bill keeps growing. This looks like the first real alternative. Want to give it a proper test.

Hey Product Hunt community 🙌

I’m Katja, co-founder of Mantle Chat.

We built Mantle Chat because we think AI at work should feel collaborative, not isolated. When AI is part of the team workspace, it becomes more powerful, easier to adopt, and more natural for everyone to use.

The idea is simple: instead of everyone using AI alone, the whole team can learn, collaborate, and work with AI together.

How we got here?

We spent time talking to modern teams and noticed one thing: teams are already using AI, but not really together.

They have one tool for team messaging, another set of tools for AI, and a lot of work happening in between. Team communication happens in Slack or Teams, while AI work happens in personal conversations with ChatGPT, Claude, Gemini, and other tools. This creates a few painful problems:

• Constant switching between team messenger, AI tools, docs, and tasks

• Context gets lost every time people jump between apps

• Slack + multiple AI subscriptions quickly become expensive

• People use AI quietly, but don’t always share how they’re using it

• AI conversations stay private, so teammates duplicate work

• The AI has no real context on what the team is working on

• Prompts and responses get copied around manually

• Non-technical teammates often find AI harder to adopt

• Companies want everyone to use AI, but most AI tools still feel individual or developer-focused

The result is strange: AI is everywhere, but teamwork around AI is still fragmented.
So we asked ourselves: what if AI was not a separate tool, but part of the team workspace itself?

What we built?

Mantle Chat is a collaborative AI workspace for teams.

It brings real-time team messaging, AI models, agents, tool integrations, and shared knowledge into one place.

What you can do in Mantle Chat:

• Chat with your teammates in Slack/Discord style channels, DMs, and threads.

• When you need help from AI, you can mention (@) 60+ models GPT, Claude, Gemini, Grok, DeepSeek, directly inside the conversation.

• The AI can respond in the same thread, where the whole team can see it, discuss it, reuse it, and build on top of it.

• You can also keep private AI chats when you need to work individually.

• Mantle Chat gives teams a shared knowledge base, so uploaded docs, workspace context, and project information can become part of the AI’s understanding. Instead of manually copy-pasting background into every prompt, your team can give AI the context it needs once and use it across conversations.

• Teams can also build shared AI agents with custom instructions, knowledge, schedules, and integrations. These agents can run manually, on a schedule, or be triggered by connected tools. (For example, you can create agents for research, PR reviews, meeting notes, analytics reports, customer requests, Linear updates, Stripe events, and more.)

• Mantle Chat connects with 30+ tools, including Linear, GitHub, Google Drive, Notion, Slack, and Stripe, so AI can help with real workflows, not just answer questions.

• Give the whole team access to AI without IDEs or complicated setup

• Reduce the need for separate team chat and AI subscriptions

And honestly, figuring out AI as a team is much more fun and effective than doing it alone.

Is it for you?

Mantle Chat is built for teams that already use AI, or want to start using it together.

• For startup teams: Mantle Chat gives you one place to talk, think, plan, and work with AI. You can keep product discussions, customer insights, research, and AI-generated ideas visible to the whole team.

• For product and design teams: Mantle Chat helps you brainstorm, summarize feedback, compare ideas, write specs, analyze research, and keep AI outputs connected to the conversations where decisions happen.

• For engineering teams: Mantle Chat lets you bring AI into technical discussions, create PR review agents, summarize Linear issues, connect GitHub, and reduce context-switching between tools.

• For operations and support teams: Mantle Chat can help automate recurring workflows, generate reports, summarize requests, and create agents that run on a schedule or react to events.

• For non-technical teammates: Mantle Chat makes AI feel approachable. You do not need an IDE or developer workflow to use agents, models, and automations. You just work inside chat.

• For cross-functional teams: Mantle Chat helps product, design, engineering, operations, support, and leadership stay aligned by keeping conversations, AI outputs, shared knowledge, and workflows in one place.
