About Edgebook

Demo version · October 2026

Edgebook is a free trading journal. Drop in the CSV your broker already gives you, and it turns your fills into trades, takes out every fee, and shows you what you actually took home. Its built-in coach, WrenAI, reviews every trading day: what you did right, what you did wrong, and what to do differently tomorrow.

This is the demo

You're using the demo version of Edgebook. It's free, it works with thinkorswim and Robinhood exports, and your journal is saved on your own device behind your own passcode. Features will keep changing as Edgebook grows.
