LedgerMind is a GitHub project that gives AI agents a long-term memory stored on your own machine. It records conversations, pulls out knowledge worth keeping and settles conflicts when stored facts disagree.
The saved context can then be reused across different agent clients, so an agent does not start from zero each time. Because it is local-first, your data stays with you. The project is free and open source, and is best suited to developers comfortable setting up tools from a repository.
