What is Pensyve?
Pensyve stores facts, conversations, observations and action outcomes so an agent can retrieve them in later sessions. A Rust engine uses SQLite and local embedding models, and you can use it through Python, an MCP server, a CLI or a REST API. Local use needs no account or API key.
Pros
- Local use needs no account or API key
- Many interfaces: Python, MCP, CLI, REST
- Searches memory by meaning
Cons
- Licence is not a standard one GitHub recognises
- Young project
Who should use Pensyve
Developers who want local, persistent memory for their agents.
Who may not need it
