Trustworthy by design.
The assistant can't act on your behalf without your explicit permission. Guardrails you can see and controls you can adjust, not promises in a policy.
One platform · many kinds of assistant
Think better. Keep what you learn.
ThoughtPartner reads what you share, remembers what matters, and thinks it through with you. Your data stays yours. You set the boundaries. And you get sharper every time you use it. Choose the assistant that fits.
What every ThoughtPartner shares
Built on four promises.
Your data stays yours.
Your assistant's memory lives in your own private space, Lintel-managed or self-hosted. You can read everything it knows, download a copy, and take it with you if you ever leave.
You set the rules.
Your assistant starts read-only. You open capabilities one at a time. Every boundary is enforced by the product, and it holds on every channel the assistant runs on.
Progress you can see.
The assistant helps you improve measurably over time: sharper recall, harder questions, visible growth. A thinking partner that moves with you, not an oracle you lean on.
ThoughtPartner helps you improve yourself and learn to use AI well — a sparring partner, not an oracle.
