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 is unlimited.
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.
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 trial; you pay for the period you want, and your plan is active for exactly that long.
When your paid period ends, your account automatically reverts to the Free plan — nothing is charged without you initiating a new payment. You'll see a banner in-app a few days before expiry as a reminder.
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.
