Who is Liable
when AI is Unreliable?

Planisphere harnesses the AI you already use: memory, context and knowledge graphs on your desktop, boundaries in the console, all powered by an Evidence API that lets you seal and prove anything it did.

FAQ

Useful answers.

Is Planisphere an AI?+

No. It's the harness around the AI you already use. Your AI systems do the work; Planisphere keeps them current, watches the boundaries you care about and writes down what happened.

What stays on my computer?+

Your knowledge graphs and their checkpoint history, and the memory your AI systems share. None of it needs an account. The console sees only what you choose to report from a connected computer.

What does verifying a receipt establish?+

That the record is intact, who signed it and whether it still stands. It doesn't establish that a record is complete, or that the work was right.

Is Planisphere Desktop free?+

Yes. Download it and use it on your computer, with the AI systems you already use. The console is for teams, and its first 1,000 credits every month are free.

Do I need the console?+

Not to start. Planisphere Desktop works on its own. The console is for when a team wants one place for records, reviews and receipts.
