EverMemOS
Open source memory layer for AI systemsGive AI long term memory and consistency
Highlights
What you can do with it
- Add persistent memory to an AI assistant or agent
- Keep long conversations and projects consistent over time
- Benchmark how well a memory system retains context
How to use it
- 1 Visit the EverMind site and open the GitHub repository
- 2 Download or clone EverMemOS and read the setup guide
- 3 Connect it to your AI application as a memory layer
- 4 Join the waiting list if you want the broader experience
Who it is for
Pros
- Open source code you can inspect and self host
- Benchmark numbers published for the memory system
- Free entry point through GitHub
Limitations
- Free access today may change when the wider product launches
- Early infrastructure can need engineering effort to integrate
- The benchmark result is the project's own reported figure
What EverMemOS is
EverMemOS is the memory layer of the EverMind project, which sets out to give AI continuous, almost unlimited memory and long term consistency. Most assistants forget earlier parts of a conversation, so every session starts from zero and users repeat themselves. EverMind tackles that with three pieces: EverMemOS, an open source memory operating system for AI that the team says scored 92.3 on the LoCoMo benchmark; EverMemBench, a standard for evaluating memory systems; and EverMemModel, an engine built around parameterized long context understanding. The memory system is available for free on GitHub right now, and the site also offers a waiting list for people who want the fuller experience as it develops. For developers, that means an assistant can remember a user's preferences, past decisions, and project history without everything being re-explained at the start of every session.
What you can do with it
- Plug an open source memory system into an AI app or agent
- Keep user context, preferences, and history across sessions
- Use EverMemBench style evaluation to check memory quality
- Follow the roadmap through the waiting list for newer features
- Study the open source code to see how memory is stored and retrieved
Who it is for
- Developers building assistants that should remember returning users
- Researchers who need to measure how well memory holds up over time
- Product teams tired of AI that forgets context in the middle of a project
- Teams running long projects where continuity matters more than speed
What to watch out for
The free GitHub access reflects the current stage of the project; terms, availability, and pricing can change as EverMind moves from open source release to a fuller product. Integrating a memory layer is real engineering work, not a drop-in widget, so plan for development time and testing. The 92.3 benchmark figure is reported by the project itself, so treat it as a vendor claim and run your own evaluation on your own data before relying on it. As with any early infrastructure, keep backups of important state and keep your own records of critical facts outside the memory layer so a bug or reset does not wipe context you depend on.
