- Perplexity Pro is built to search the web and cite what it found. ChatGPT Plus is a general assistant that also has Deep Research tasks.
- We could not read a limit for Perplexity Pro in a source we can cite, so the table leaves that cell empty instead of repeating a number from a blog.
- Both official pages block automated reading. Every figure in this comparison is third-party and labelled as such.
- If most of your questions end with "and where does that come from?", start with the search-first tool. If you mostly draft and rewrite, start with the assistant.
