Perplexica pros and cons
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
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
