Best for
  • Developers using Claude Code or other AI coding agents to incorporate real-time information.
  • Developers needing to resolve rare errors or lacking documentation.
  • Developers needing design review or complex problem-solving support.
  • Privacy-conscious developers who want local data storage.
  • Researchers who need AI-assisted management of large note collections.
  • Users of Markdown editors like Obsidian.
Not for
  • Users who don't want to depend on OpenAI API or lack an API key.
  • Users needing search capabilities via non-OpenAI models.
  • Users needing offline search or local search abilities.
  • Users needing cloud sync and mobile access (unless using the paid cloud service).
  • Minimalists who want zero configuration.
  • Scenarios requiring large-scale vector databases and complex retrieval (local SQLite may be insufficient).
Required permissions
  • Requires a valid OpenAI API key, and possibly API tier 4 or organization verification for o3 model access.
  • Network access to OpenAI API.
  • Write permissions for configuration directory during installation.
  • Read and write to the local filesystem (default: ~/basic-memory).
  • Perform file and directory operations (create, edit, delete).
  • Access local SQLite database (or Postgres/Milvus if configured).
Risks and side effects
  • API key leakage: ensure key is kept secure and not committed to public repositories.
  • API usage may incur costs; monitor usage.
  • AI agent may provide inaccurate info; verify critical results.
  • Dependency on OpenAI service availability and potential rate limits.
  • Tools have write operations that may unintentionally modify or delete notes.
  • Edit operations may overwrite existing content, though there are protections.
  • Semantic search and reranking features may require model downloads, adding latency.
  • Local data backups are the user's responsibility.
