Connect GitHub, Notion, Slack, and VS Code into one intelligent context layer. Ask anything and get answers grounded in your real project data.
How it works
Unified Store
Semantic Indexing
OAuth into your tools in one click. We handle the rest.
From sign up to shipping your first PR in under five minutes. No config files, no setup scripts — just connect your tools and start asking.
Sign up with email. No credit card needed on the Free plan — 25 AI queries/day out of the box.
You land on the dashboard with an empty workspace ready to connect.
Open Integrations, pick GitHub, Notion, Slack, Linear, or Google Drive, and click Connect. One OAuth popup per tool — that's it.
Tokens are encrypted with AES-256-GCM before they ever touch our database.
ContextOS pulls your repos, pages, threads, and issues, splits them into semantic chunks, and embeds them into a unified context store.
Webhooks keep everything fresh automatically as your team commits, edits, and chats.
Go to the Chat page and ask a real question — "why did auth break last week?" — and get a cited answer grounded in your real commits, docs, and Slack threads.
Every answer lists its sources so you can click through and verify.
Grab the ContextOS extension, paste the API key from Settings, and ask questions without ever leaving your editor.
The extension also has a Chat sidebar, inline selection queries, and a command palette full of actions.
Open the palette and run "Commit, Push & Open PR", create a Linear issue, post to Slack, or draft a Notion page — all from the editor using your connected accounts.
One workflow, every tool. No tab-switching, no context loss.
Five surfaces, one context layer. Here's what each one is for.
See every connected service, recent activity, system health, and how much context has been indexed. One glance tells you whether your AI has fresh data.
A ChatGPT-style interface that answers from your actual GitHub, Notion, Slack, and Linear. Streaming responses, citations inline, history on the left.
Connect or disconnect any provider. See last sync time, force a re-sync, or revoke access. Tokens never leave our encrypted store in plaintext.
Sidebar chat, inline code questions, and a command palette with every workflow. Uses your API key so it's authenticated to your exact workspace.
From the extension palette: commit + push + open a PR, create a Linear issue, send a Slack message, or draft a Notion page — using your connected OAuth accounts, not a separate token.
Pro tip — start with one integration
You don't need to connect everything on day one. Plug in GitHub first, ask a few questions in Chat, then layer on Slack or Notion once you see the value. The context store grows as you go.
Testimonials
"ContextOS transformed how our team handles context switching. Instead of digging through Slack and GitHub, we just ask the AI. It's like having a senior dev who knows everything."
"The VS Code extension is a game-changer. I can query our entire codebase, Notion docs, and Slack history without leaving my editor. Saved me 10+ hours this week alone."
"We onboard new engineers in days instead of weeks. They ask ContextOS about our architecture, past decisions, and ongoing projects. It's like institutional knowledge on demand."
