Koot delivers end-to-end encrypted peer-to-peer messaging, voice & video calls, and file sharing — with no servers storing your messages, ever.
All messages and files are encrypted using industry-standard protocols. Only you and your contact can read them.
Conversations happen directly between devices. No message storage on servers — data never leaves your control.
No app to install. Works on any device with a browser — phone, tablet, or desktop.
Share images, videos, documents and more — transferred directly peer-to-peer, encrypted in transit.
Crystal-clear encrypted calls using WebRTC — routed peer-to-peer whenever possible.
Create encrypted group chats and multi-party calls with your team or colleagues.
Chat with an AI that runs entirely on your own machine. Your conversations never leave your network.

Paste a key from Gemini, Groq, OpenRouter, or any OpenAI-compatible endpoint. Nothing to install, works on a phone, ready in about a minute. Free tiers are available from several of these providers.
What it can actually do for you:
“Create a task to fix the loading dock by Friday, assign it to Umak.” It also reads back real status — what’s overdue, blocked, or stalled — computed from your actual tasks, not guessed.
Ask for a report, a checklist, a slide deck or a spreadsheet and it lands in Koot Documents, formatted and editable — not as a wall of chat text.
Type @ai in any group. It sees the recent conversation, and anything it creates is shared with that group automatically. You approve each action before it happens.
Send a picture of a damaged part, a delivery note or a whiteboard and ask about it directly.
Requests go straight from your browser to the provider you chose. Koot’s servers never see your key or your conversation. You can share your AI with a contact, or turn it off, whenever you like.
Worth knowing: your chosen provider does see what you send it. If that matters for a particular conversation, use option B below instead.
Download and install Ollama for Windows / Mac / Linux from the official site:

How it works
The AI model runs on your machine. Only the question travels to your bridge — never to any third-party AI service.
CUDA_VISIBLE_DEVICES=0 in your environment before starting Ollama. This makes inference ~10× faster than CPU-only.
Four kinds of file, all editable in the browser with no install:
Formatted text — reports, procedures, handovers. Downloads as a real Word .docx.
A full grid editor with formulas. Downloads as a real Excel .xlsx.
Slide decks you can edit slide by slide.
Quick plain-text jottings — a list, a reminder, meeting notes.
Koot AI can create any of these for you — see the Koot AI tab.
Every document is stored in your own browser on your own device. There is no copy sitting on a Koot server — which is the point, but it has one important consequence:
⚠️ Clearing your browser's site data deletes your documents permanently. Nobody can restore them for you. Use Settings → Backup & Restore to keep an encrypted copy somewhere safe.
You can also download any file to your computer at any time from the editor's Download button.
Open a document and press Share, then pick the contacts who should have it. From then on, your edits travel directly to their devices, encrypted — the same peer-to-peer path your messages use.
Ask Koot AI for a document inside a group and everyone in that group gets it automatically, no sharing step needed.
Everyone shared on a file can edit it. The most recent save wins, so for now it's best if two people don't rewrite the same section at the same moment — like a shared drive, not a live co-editing canvas.
Nothing is lost. If a person you shared with isn't online, the change waits and delivers itself the moment you're both reachable again — so a document can take a little while to appear on a colleague's device, especially the first time.
If a file hasn't arrived yet, it simply isn't on that device yet — give it a moment and reopen it rather than recreating it.
