AI investment research for people who do their own DD
Stress-test your investment thesis before you risk money on it
Deepest sends your thesis to several of the best AI models at once. Each one attacks your reasoning, and where they disagree is exactly where your risk is hiding. One model can be confidently wrong. A room full of them shows you the cracks.

Disagreement between models is the signal
Watch several top models pull apart the same investment thesis, then see where they land.

Three steps to a conviction map
It takes about a minute. The Investment Thesis Stress-Tester persona and Compare mode do the heavy lifting.
Turn on the skeptic
In a new chat, open the + menu and pick the Investment Thesis Stress-Tester persona. It flips every model into skeptic mode, so their job is to attack your reasoning, not agree with it.
Pick a few models and Compare
Select two or more top models and switch on Compare mode. Now you see each model attack the thesis and exactly where they agree and split.
Paste your thesis, read the map
Drop in your idea and the reasoning behind it. You get back a conviction map: points of agreement, the unresolved disagreements, and the single biggest unknown to resolve before you risk anything.
Research tooling, not a tip service
It sharpens your reasoning, it does not pick for you
Deepest never gives a buy or sell call, a price target, or position sizing. It analyzes the quality of the thesis you bring: the assumptions it depends on, how to check them, and what would prove it wrong. The decision stays yours.

Questions investors ask
What an AI thesis stress test is, and what it is not.
