For individuals

A second brain for people whose work runs on connections.

Pensiv curates your notes, research, calls, documents, and AI conversations into knowledge you can question, search, and use again.

What people use it for

For people who think across too many tabs.

Pensiv spots the same idea across notes, papers, and calls that look different on the surface.

An AI that picks up where you left off

Your AI helped you think last week. Today it asks who you are. Pensiv hands back what the last session knew, so you don't rebuild it every time.

Founder's knowledge

Every decision, bet, and 'we tried that' in one place you can question.

Ask it anything

Questions only your own knowledge can answer.

Where have I run into this before — and what did I conclude?

Your knowledge, yours

Private by default. Evidence-first. You stay in control.

Turn everything you learn into knowledge you can use again.
