See what your conclusions rest on.

Every answer has a trail you can follow. Open a finding to see its sources, what supports it, and what it still assumes. Challenge a source. Change a question. Remove a piece of evidence. See what else needs to be reconsidered.

Should I take the Church Street lease at £38k a year?

Yes — take it. Church Street has strong foot traffic, and £38k is a fair rent for the area. It’s a great opportunity.

Fair questions.

Which AI model does the thinking?

Google Gemini helps generate questions, investigate findings and develop answers on your board, and Exa searches the web for the sources behind them. You remain in control of what gets explored and what stays on the board.

Where does what I type go?

Your boards stay in a database on the machine running Vitark. Gemini and Exa see only what a run needs, and only when you press it — the privacy page says exactly what.

What does it cost?

Vitark itself is free. Runs use your own Gemini and Exa keys, so those services bill for what you use — and nothing runs unless you press it.

What if a source is wrong?

You can inspect the sources behind findings and challenge or remove them. Vitark helps you see what rests on that evidence, so you can reconsider the conclusions it affects.

Does Vitark research on its own?

Vitark can investigate the questions you choose to explore. You can also ask AI to suggest questions based on your goal. You decide what to investigate and what to keep on your board.
