"Typical AI journal" reflects the common shape of paid AI journaling tools as of July 2026. Check any specific product yourself.

Not financial advice. Merlin describes your own past trades: it never tells you to take or avoid a trade.

Try before you trust

Most journals make you sign up to see anything. Merlin opens the full product in one click. Judge it with your own eyes before it ever asks for an email.

Built for how futures traders work

Tick values, whole contracts, trailing drawdown that freezes at your starting balance. The details generic journals get wrong.

AI grounded in your own numbers

The deterministic engine computes every number first; the AI only narrates what was already proven. If it cites a figure, it's yours.

The comparison that matters is with your own data.

One click opens the full product. Import a statement and judge the analysis yourself.
