Main tasks
Write an entry before you act
Add an entry with the ticker, what you plan to do, why, what would prove you wrong, how confident you are and when to look again.
Ask hard questions
Tap "Ask hard questions" on an entry. The AI asks about risks and gaps in your reasoning, never tells you what to do, and your answers are saved with the entry.
Review when the date comes
Open the Review tab, where entries due for review come first, and you get a reminder on the review date. Compare your reasoning with what happened, then note whether you followed your exit rule and what you learned.
See what your record says
Open Insights to see how often your reasoning was right, by where the idea came from and by how confident you were.
Search and export
In the Journal tab, search or filter by status or ticker, and export your entries as a CSV file.
