Hindsight
People recommend Hindsight as a memory layer for AI agents that can cut token use over time and replace hand-kept memory files. The caveat is that stored memories were sometimes ignored by agents after a while.

if you do similar stuff often your token usage will drop after awhile of using a memory subsystem like hindsight or honcho

What hackers pick instead
- EngrimOpen-source local memory engine for AI agents, built on SQLite, with local embeddings and no API key or external service needed. Critics note it is still limited by effective context size.21recommend
- MemPalacePeople recommend it as a locally managed memory layer for AI agents that retrieves past conversations well. Critics say independent end-to-end tests scored far below its retrieval benchmarks.9recommend
- GrovPeople recommend it for cutting exploration tokens and recalling past sessions for Claude Code. One user says it is rough around the edges, and it needs an API key.8recommend
- claude-memRecommended as an open-source Claude Code memory plugin that recalls past prompts and replies without many tokens. One caveat: it only records from install forward.8recommend
- LettaFree open-source agent framework with selective memory retrieval and long-context handling. Critics point to heavy dependencies and embedding API costs.8recommend
