I built samemind, a lightweight memory system that stores an AI agent’s state as plain Markdown files in a Git repository, eliminating the need for databases, cloud storage, or API keys. The solution is engine-agnostic, supporting 12 popular LLM platforms such as Claude, Code, Cursor, and půOpenCode. By leveraging Git’s versioning, samemind provides persistent, tamper‑evident memory that can be accessed locally or via standard Git workflows.
