The honest brief

GPT Researcher

Deep research you fully own and self-host, swapping in whatever model and search backend you prefer — no vendor lock-in.

  • Apache-2.0, free to self-host
  • Works with any LLM and search engine
  • Cited, long-form reports in minutes
  • Runs as library, API, or MCP server

  • Setup complexity for beginners
  • You pay your own LLM + search costs
  • Needs prompt tuning for niche domains
  • Basic built-in analytics

Perplexity

Pairs a consumer cited-answer engine with the Sonar API, so the same retrieval layer powers both.

  • Inline citations on synthesized answers
  • Cited search API for your own apps
  • Pro lets you pick a model per query
  • Strong on fresh, fact-based queries
  • Citations can misattribute or be wrong
  • Weak on niche topics with thin sources
  • Best features gated behind Pro
