Built by a trader, for traders.

Playbook Refinery was created by Pierson Hosie after years of keeping messy, inconsistent trading journals. Reviewing trades by hand was slow, biased, and easy to skip — exactly when it mattered most. The trades that hurt the worst were never the losses themselves, but the undisciplined wins that quietly built bad habits.

Playbook Refinery fixes that. Drop in a chart screenshot and a few notes, and an AI mentor grades the trade like a seasoned coach — rewarding sound process, flagging real mistakes, and writing the journal entry for you. Over time, your dashboard shows whether your discipline is actually improving.
