Run a free stress test →Write down why you bought. penKeep checks filings, news, and earnings against your reason, and asks you to look only when something actually tests it.
Start your record →Six months later, every decision has a neat explanation. The original uncertainty, the warning you dismissed, and the condition you promised to watch have disappeared.

Alerts disappear after telling you what happened. penKeep ties evidence to the belief you recorded, captures the decision you made, and returns it later when the outcome can be reviewed.
No. Most weeks you will hear from us once, in the Sunday digest. We only send a real-time alert when something directly tests one of your exit conditions.
