It provides summary metrics (total memories, active days, peak day count, and longest streak) alongside a visual heatmap of activity across the last year. Below the heatmap, a chronological timeline details individual memories with their type, source, tags, time, and confidence.

## Achievements Under the summary metrics, the **🏆 Achievements** panel shows badges for usage milestones. Earned badges show the date they were earned. Locked badges show progress toward their target. | Badge | Requirement | | - | - | | First Agent | Create your first agent | | Squad | Create 5 agents | | Centurion | Store 100 memories | | Archivist | Store 1,000 memories | | On a Roll | Store memories 7 days in a row | | Peacemaker | Resolve your first [conflict](/ui/conflict-resolution) | | Policy Setter | Save an [expiry policy](/ui/expiry-policy) | | Connected | [Connect](/ui/connections) an AI tool to Memanto | A celebration card appears when you reach a new milestone. Milestones you had already reached before achievements existed are recorded without a celebration. Progress is saved to `achievements.json` in the Memanto data directory, so it stays the same in any browser.
