What it does, how projects remember things, and how billing works. If something's missing, use the contact page and we'll add it here.
Create an account, then create your first project. Every project starts with a blank slate — a mission, a status, and an empty timeline. As you work, you add sessions, decisions, ideas, and resources to it. The next time you open the project, ContextOS surfaces everything that matters so you can pick up exactly where you left off.
Free accounts get 5 projects and unlimited sessions, decisions, ideas, and resources — enough to fully try the product before upgrading.
ContextOS is built around six object types, all attached to a project:
Every project gets a 0–100 health score based on recent activity, whether next steps are recorded, whether decisions are documented, and how fresh the project is. A dropping score is an early warning that a project is quietly losing its story — usually a sign to log a quick session before you forget what you were doing.
AI Resume reads a project's recent sessions, decisions, and blockers and generates a short briefing: what happened, what's unresolved, and what to do next. Free accounts get 5 resume requests a month; Pro gets 100 a month.
AI Next Step looks at the same context and suggests the single most useful action to take next, so you're never staring at a project wondering where to start.
Both panels show how many credits you have left for the month, with a warning once you're down to your last 10 — so you always know where you stand before you hit the limit.
ContextOS Pro is $9/month or $90/year, billed in crypto — USDT on Solana or BSC. There's no credit card required and no auto-renewing subscription; you pay for the period you want, and your plan is active for exactly that long.
As your Pro period gets close to ending, you'll see an amber renewal banner on your billing page once you're within 7 days of expiry, with a one-click renew option. If a payment isn't made in time, the banner switches to a clear expired state — your account reverts to Free automatically, and you can renew at any point afterward to pick Pro back up.
Nothing is ever charged automatically — every renewal is a new payment you initiate yourself.
Common questions about the product are answered on the homepage FAQ. If you don't see your question there, reach out via the contact page.
A public API is planned so you can create and read projects, sessions, and decisions programmatically — useful for CLI tools, editor plugins, and automation. It isn't available yet.
