I kept losing time on vendor docs the same way: search the page, miss the breaking-change callout, copy an example from the wrong version, then debug for an hour.

Generic chat on a URL does not fix that. It summarizes the intro, skips the warning box, and invents a parameter that used to exist.

What actually helps when you are in a guide:

1. A TL;DR plus the traps, not a rewrite of the hero paragraph

2. Reordering the page for the job you have (understand / set up / fix / find an example)

3. Answers that cite a heading you can jump to

4. A clear “this is not on the page” instead of a confident wrong snippet

5. Not paying to re-parse a page that has not changed

That is the bar I built DocPilot against. Chrome side panel, your own Gemini key, no analytics pipeline for the page text.

If you live in Stripe, Tailwind, Docker, or internal wikis, try it on the last page that burned you and see whether the gotcha box matches what you actually hit.
