khoj
Khoj is a self-hostable “AI second brain” that provides chat and research-style Q&A over local and web/document sources using semantic search and LLMs. It supports multiple frontends (web, desktop/editor integrations) and can run agents and automations.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
From provided materials: TLS enforcement and secret-handling practices are not documented. Dependency list includes several security- and parsing-related libraries (e.g., defusedxml), but also many heavy ML/web dependencies (transformers/torch) with a non-trivial attack surface. Auth and fine-grained scope details are not provided, so scores are conservative.
⚡ Reliability
Best When
You want a self-hosted assistant that can index many document formats and answer questions using retrieval plus an LLM, optionally using different LLM providers/models.
Avoid When
You need a clearly specified, documented public API contract (OpenAPI/SDK) or strict operational guarantees (SLA, idempotency/retry semantics) documented for programmatic use.
Use Cases
- • Private chat over your documents (PDFs, Markdown, Notion exports, etc.) via semantic search/RAG
- • Building custom agents with specific tools/knowledge personas
- • Automating research and delivering newsletters/notifications
- • Using local LLMs for offline/self-hosted assistant capabilities
- • Integrating the assistant into tools like Obsidian, Emacs, and mobile experiences
Not For
- • A fully managed SaaS-only solution if you require zero self-hosting
- • A strict “API-only” product with guaranteed stable external REST/SDK contracts (no API spec provided in supplied content)
- • High-compliance environments where you need clearly documented enterprise security controls from the provided materials
Interface
Authentication
The provided materials confirm MCP is included as a dependency, but do not provide concrete auth mechanism details (e.g., OAuth flows, API keys, scopes). Assume authentication exists in the full product but cannot score it precisely from given content.
Pricing
README mentions a cloud app and that there is a “Get started - free” claim in repo description; no concrete limits or billing details were provided in the supplied content.
Agent Metadata
Known Gotchas
- ⚠ Provided materials do not include MCP server details (tools, schemas, error codes, pagination), so agent integration may require manual exploration of the running server and its tool contracts.
- ⚠ RAG/chat systems can produce non-deterministic outputs; agents should not assume stable response schemas without explicit tool-level guarantees.
