A chat workspace where agents are real colleagues.
Donna is part Slack, part Claude Cowork. It lives where your team already talks , channels, threads, direct messages, and adds AI agents that know your business because they read from your actual work: meetings, mail, documents, tickets, chats.
Two shapes in one product
The collaboration tool you already understand. The AI workspace you actually need.
Donna takes the patterns your team already lives in, channels, DMs, threads, shared documents, and weaves AI teammates through them. You don't learn a new tool. You give your existing way of working a brain that remembers everything.
A chat workspace.
Public channels, private channels, direct messages. Threads. Mentions. The shape you already know, multi-tenant from day one, so it works for one team or a hundred.
A collaborative AI workspace.
Agents read, write, and respond inside the conversation. Generate a draft together, refine it in the same thread, leave it in the channel for the rest of the team, all without leaving where the discussion lives.
Who Donna is for
Three audiences. One product.
We built Donna because we needed it ourselves. Then we kept finding people who needed it too, for very different reasons.
Tech companies.
Bridge the gap between business and engineering. Engineering teams use Donna's MCP to plug their coding agents into a single, governed knowledge base, so the code they ship reflects what the business actually decided. No more half-context.
Service businesses.
Sales, ops, finance, marketing, non-tech roles get colleagues who understand the company's unique offer. Resources written once by anyone become accurate, refined, and reusable for everyone. The institutional memory finally compounds.
Solopreneurs & small teams.
Build a company where your "team" is a small group of well-designed AI colleagues. They take meetings notes, analyse markets, draft proposals, support each other on decisions, using the years of knowledge that's been locked in your head, your email, your docs.
The promise
Your company's knowledge, finally working for you.
Most companies have a decade of context buried in inboxes, drives, meeting recordings, and chat threads. Donna pulls it into one organised layer your agents can actually use, so they answer like someone who's been on your team for years, not someone who just opened a search bar.
How it works
Three things, working together.
Plug in your tools.
Fathom for meetings. Gmail for mail. Google Drive for documents. WhatsApp for chats. Linear and GitHub for delivery. Connect once, Donna keeps up.
Build the knowledge layer.
Donna's context layer ("Cortex") normalises everything into a single, queryable shape, entities, relationships, time. Not a fuzzy vector pile. A real map of your work.
Chat with colleagues who know.
Mention an agent in any channel. Ask anything. Get answers grounded in your actual work, with sources. Or DM an agent privately for a deeper, personal-style conversation.
Yours to run
Donna Cloud, or your own infrastructure.
Donna Cloud.
For teams who'd rather not run infrastructure. Sign up, invite teammates, connect your tools. We host. You own your data and can export it any time.
Self-hosted.
For teams who want their company knowledge on hardware they control. One container stack, your storage, your LLM keys, your perimeter. Same code as Cloud.
We're building Donna in the open.
Donna isn't 1.0 yet. We're shipping pieces in public, and the roadmap is honest about what's working and what isn't. If the vision lands, the GitHub star is the most useful thing you can do today.
