Why not just ask Claude?
Because Claude doesn't know your numbers. Massari does — and it plugs right into Claude, so you keep the AI you already reach for.

Ask Claude about a company's balance sheet and it answers from training data that may be a year stale — or it reasons its way to a figure that looks right and isn't. For a decision with real money behind it, that's the one thing you can't have.
Massari is the layer that fixes it. Every answer is built on live SEC filings, market data, and your own portfolio — and every number traces back to the document it came from. It connects to Claude directly, so you keep the plain-English experience you like and lose the guessing.
Grounded, not guessed
Every figure comes from a real filing or dataset — and you can click it to see the source yourself.
It knows your portfolio
Massari holds state Claude can't: your holdings, cost basis, and exposure.
