features

Everything a project needs
to be resumable.

One job — resuming a project instantly — built from session history, decisions, GitHub activity, and a clear next action, so nothing depends on you remembering to write it down somewhere else.

the core feature

Resume any project in 30 seconds.

One click generates a briefing from everything below — your sessions, decisions, next action, and connected GitHub activity — so you never open a project cold.

Last session
Implemented Stripe webhook.
Current blocker
Webhook signature failing.
Recent decision
Switched from Clerk to Auth.js.
Next action
Test webhook retry flow.
what feeds it
Session History
A log of every session: what you built, what you learned, what blocked you.
Next Action
The one thing to do next — always visible, never buried in a backlog.
Decision Log
Why you chose one path over another — not just what you decided.
Project Memory
The mission, current goal, and overall story — the one place everything else connects to.
Resource Vault
Links, repos, docs, and API references, filed under the project they belong to.
Ideas
Half-formed thoughts and future directions, saved before they're lost.
Context Health
A live score showing which projects are quietly losing their story.
Saved Briefings
Every Resume briefing stays with the project — read it anytime without spending another AI credit.
the shift toward automatic

Less typing. More memory.

Most of ContextOS still runs on what you choose to log. GitHub Context is the foundation this is built on — connect a repo once, and Resume, Smart Blockers, and Copy Context all draw from it automatically.

GitHub Context — connect once, stays current
Automatic
Connect a repository to a project and every Resume briefing includes commits, merged PRs, and open issues since your last session — read-only, per-project, disconnect anytime. This is also what Smart Blockers checks against, so the more current your repo, the more useful both features get without any extra effort from you.
Smart Blockers
ContextOS notices when something's stuck, without you having to say so.
Three rule-based checks run against your connected GitHub repo every time you generate a briefing: no commits in 14+ days, your oldest open issue idle for 5+ days, or a pull request sitting unmerged for 2+ days. These are deliberately not AI-generated — each one is a plain boolean check against real activity, shown separately from the AI-written summary, so if it says you're blocked, there's a specific, inspectable reason why.
Copy Context
Your whole project's memory, one click from living in any AI chat.
Every briefing ContextOS generates — where you left off, current blockers, recent decisions, next step, key context — can be copied as clean markdown with a single click. Paste it into Claude, ChatGPT, or Gemini and skip re-explaining your project from scratch. No new integration, no extra AI call — it reuses exactly what Resume already built.

Frequently asked questions

AI Resume is the core feature — one click that generates a briefing from your session logs, decision log, next action, and connected GitHub activity. Rule-based Smart Blockers and one-click context export for any AI chat build on the same data.

When you return to a project, ContextOS generates a short briefing summarizing your recent sessions, open decisions, and the current next action so you can start working immediately instead of rereading everything.

Rule-based checks against your connected GitHub repo — no commits in 14+ days, an open issue idle 5+ days, or a pull request sitting unmerged for 2+ days. They're deterministic, not AI-generated, so every flag has a specific, verifiable reason.

Copies your entire project briefing — where you left off, blockers, recent decisions, next step — as clean markdown, ready to paste into Claude, ChatGPT, or any AI chat. No re-explaining your project from scratch in a new conversation.

No. ContextOS tracks one clear next action per project plus the history behind it. Keep your task manager for granular daily to-dos — most users run both.

Yes — a session log takes under a minute at the end of a work block. The AI resume briefing pays that time back the next time you return to the project.

Yes, optionally. Connect a repository to a project and your AI briefings will include commits, merged PRs, and open issues since your last session — plus Smart Blockers computed from that same activity. It's read-only, per-project, and you can disconnect anytime. ContextOS works fully without it.

Yes. Each briefing is saved to its project, so you can re-read it anytime without spending another AI credit. Credits are only used when you explicitly regenerate.

Yes. Projects are private to your account, and you can export your data at any time.
