Best for
  • Individual developers who want Perplexity search/reasoning in their coding environment
  • VS Code users who benefit from auto-configuration
  • Users who want to integrate Perplexity features across multiple IDEs
  • 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
  • Enterprise users who need official support or reliable APIs
  • Users without a Perplexity account to login
  • Users who prefer the official API key approach
  • 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
  • Access to your local browser profiles (e.g., Chrome profiles)
  • Automate browser sessions, including login and cookie management
  • Read and write local files (config, vault)
  • Network access to Perplexity endpoints
  • 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
  • Violates Perplexity's Terms of Service, potentially leading to account rate-limiting, suspension, or termination.
  • Browser automation may be flagged as abusive by Perplexity.
  • Experimental project: APIs and behavior may change without notice.
  • Vault encryption may cause lockouts due to OS keychain issues.
  • 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.
