Answer-style search with sources you can open and check

Open Perplexity

It sits between search and reading: ask a question, get a summarized answer with sources you can open one by one. Follow-ups re-run retrieval instead of only continuing the thread, which suits digging into a topic. A deeper mode splits the question into sub-queries for broader coverage at the cost of waiting. Citations do not always line up with the conclusion, so check each one against the original before using it in formal material.

What it does

  • Answers list sources you can open to verify
  • Follow-ups re-run retrieval instead of relying on context alone
  • A deep research mode for topic-focused work
  • Narrow sources by topic scope
  • Offered as an API for your own systems

Who it is for

  • You want a sourced answer without opening a dozen tabs
  • Entering an unfamiliar field and needing a question list first
  • Comparing how sources describe the same event
  • Feeding cited results into your own application

How to get started

  1. State scope, time frame and definitions in the first question
  2. Open the source list and keep only entries that support the conclusion
  3. Use deep mode for broader coverage, then merge by hand
