Best for
  • AI users seeking high-quality prompts quickly
  • Teams wanting to build an internal prompt library
  • Learners interested in prompt engineering
  • Educators (for kids' prompt learning)
  • Enthusiasts of open-source and community-driven projects
  • Developers needing quick, API-key-free web search capabilities
  • Privacy-conscious users who prefer local search execution
  • AI application development with Claude Desktop or Claude Code
  • 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
  • Enterprises needing a dedicated private prompt management tool (unless self-hosted)
  • Users looking for specific proprietary prompt sets
  • Users needing fully offline functionality (remote mode requires network)
  • Enterprise applications requiring high-scale, reliable search APIs
  • Users needing advanced search features like custom ranking or filters
  • Accessing sites blocked by TLS fingerprinting without installing the optional browser backend
  • 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
  • May require network access for remote MCP mode
  • Local mode requires Node.js and npm installed (via npx)
  • Self-hosting requires a database (recommended PostgreSQL) and optional authentication configuration
  • Outbound network access to DuckDuckGo and other websites
  • Reads environment variables for SafeSearch, region, and CA certificates
  • Optionally reads a CA certificate file (for TLS-intercepting proxies)
  • 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
  • Prompts may contain biased or inaccurate content (community-submitted)
  • User prompts may be unfiltered; discretion advised
  • Self-hosting requires managing database and authentication, which may involve security configuration risks
  • Search endpoints may occasionally return empty results or errors, especially when blocked
  • Content fetching may be subject to SSRF protection, blocking private or loopback addresses by default
  • Misuse could lead to rate limiting or IP blocking
  • 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.
