Perplexity AI launches its main search engine on December 7, 2022: an LLM composes direct answers with cited sources instead of returning a list of blue links.
https://en.wikipedia.org/wiki/Perplexity_AISolid dots mark events whose subject is this tool; hollow dots mark events that mention it. All entries come from this site's timeline, where every event carries a reachable source.
First release: not stated. Not derived automatically. The earliest timeline event mentioning this tool may be a version milestone, a different product with the same name, or a passing mention rather than a launch; each needs checking against an official source, so this is left empty.
Starting from one vague research question, build a complete workflow that ends in a traceable conclusion: break it into verifiable sub-questions, assign independent sources to each, record findings on evidence cards, cross-verify, mark uncertainty, and finally produce a cited conclusion page.
Breaks the investment research process into seven stages and judges one by one which can be handed to AI, which AI can only assist with, and which cannot be given up one step — with a ready-to-apply division-of-labor table and an implementation checklist that help you draw AI's capability boundary and responsibility boundary clearly.
