Deep Dive: Switching from Perplexity to Khoj
Trade-offs, installation & data architecture
What you trade away
It is a broader personal assistant, but its web-search freshness, source coverage, and answer-engine polish are weaker than Perplexity's managed index and research modes.
How to deploy Khoj
Use the hosted app, or self-host the server with Docker or pip and optionally install its desktop/browser/Obsidian clients
What it takes to run
The hosted app is immediate, but private self-hosting requires Docker or Python, PostgreSQL/pgvector, model configuration and an initial document index
Where your data lives
Hosted accounts store chats and indexed documents in Khoj's cloud; self-hosting stores application data and vector embeddings in the operator's PostgreSQL/pgvector database while original synced files remain at their source
Why fork Khoj instead of vibe-coding a Perplexity clone?
A retrieval-plus-LLM answer engine is buildable, but Perplexity's search stack, source ranking, UX, mobile/browser surfaces, and model access make full parity hard.
