Never forget what you learn from AI coding sessions
Glean automatically harvests knowledge from your Claude Code sessions and transforms it into long-term memory using spaced repetition.
Español | 日本語 | 한국어 | Français | Deutsch
When AI coding sessions end, valuable information disappears:
- Code patterns and conventions you discovered
- Mistakes you made and how you fixed them
- Concepts you learnt (forgotten by next week)
- Useful commands and workflows
Glean captures all of this automatically and helps you retain it permanently.
Analyse your coding session with 9 specialised AI agents running in parallel:
| Agent | Purpose |
|---|---|
| Session Analyzer | Core harvest data generation |
| Doc Analyzer | Documentation update suggestions |
| Automation Finder | Automation opportunity detection |
| Learning Extractor | Learning point extraction |
| Followup Planner | Next task planning |
| Pattern Recognizer | Code pattern detection |
| Mistake Analyzer | Error/mistake analysis |
| Backfill Extractor | Historical session analysis |
| Dedup Validator | Result deduplication |
Built-in SM-2 algorithm schedules reviews at optimal intervals:
| Confidence | Next Review |
|---|---|
| 5/5 | 30 days |
| 4/5 | 14 days |
| 3/5 | 7 days |
| 2/5 | 3 days |
| 1/5 | 1 day |
