Best for	—	Graduate students and PhD researchers Academics doing exploratory literature reviews R&D and biomedical teams scanning new science
Pros	Gives direct answers with cited sources rather than just a list of links Self-hosted and privacy-focused, with web search handled by a bundled SearxNG instance Works with local models (Ollama) and major cloud providers (OpenAI, Claude, Gemini, Groq) Multiple search modes plus focused sources (web, academic, discussions) and image/video results File uploads for asking questions about your own documents, under a permissive MIT license	Massive 280M+ paper index with multi-source search Copilot chat makes dense PDFs far easier to understand All-in-one: discovery review writing
Cons	Requires self-hosting with Docker and a working SearxNG setup, which is more effort than a hosted service Answer quality and cost depend on the LLM you connect; good results often mean paying a cloud provider or running capable local hardware The project was recently renamed to 'Vane', so docs, image names and URLs are in flux and can be confusing Authentication and some advanced features are still listed as upcoming rather than finished	No public API for custom research pipelines No dedicated mobile app Credit-based limits can constrain heavy users on lower tiers Prioritizes breadth over rigor vs systematic-review tools AI outputs still require expert verification
