How to summarize a web page with citations in Chrome
The short answer
Ask ProofJump's side panel to summarize the page: every line of the summary cites the exact sentence it came from, highlighted in place — click to verify. Lines the page doesn't support are flagged "no source on page", so the summary can't quietly drift from the source.
- 1
Open the ProofJump side panel on the page you want summarized.
- 2
Ask for a summary of the page, a section, or a specific angle.
- 3
Skim the summary — every line carries a citation to a page sentence.
- 4
Click the citations on the lines you'll rely on and read them in context.
- 5
Drop or independently verify any line flagged "no source on page".
Any AI can shorten a page. The problem is what a plain summary hides: which lines are the page's actual findings, which are the model's paraphrase, and which are inventions. In Chrome, ProofJump produces a summary where every line is tied to the sentence it came from — so a summary stops being something you trust and becomes something you can check.
Ask for the summary in the side panel
Open the ProofJump side panel on the page and ask for a summary — of the whole page, one section, or one angle ("summarize the limitations the authors admit"). ProofJump works only from the current page's visible text, invoked by you on that tab; it doesn't blend in material from elsewhere on the web.
Every line carries its source
The summary comes back as claims, each pinned to a verbatim quote from the page. That structure is what makes it auditable: there is no sentence in the summary you can't trace. Click any line's citation and Chrome jumps to the source sentence and highlights it in the original text, with the page itself left unmodified.
Spot-check the lines that matter
You don't have to verify all of it. Check the lines you're about to act on — the number you'll quote, the conclusion you'll forward. Jumping to the sentence shows you the claim in context, which also catches the subtler failure: a technically-quoted sentence whose surrounding paragraph reverses its meaning.
Unsupported lines are flagged, not smoothed over
If the model produces a line the page doesn't actually support, ProofJump marks it "no source on page". That's the line a normal summarizer would hand you undifferentiated — and the one most likely to embarrass you later. Here it arrives pre-flagged, so you can drop it or go verify it elsewhere.
Pick where the summarizing happens
Three processing paths, your choice in settings: on-device AI where your Chrome supports it, so the page text never leaves your computer; your own API key, sent directly to OpenAI, Anthropic or Google and never through ProofJump's servers; or ProofJump's Pro cloud. For the network paths, an optional local PII redaction switch replaces emails, phone numbers, card numbers and API tokens with placeholders before sending, and restores them on your device afterwards — the citation anchoring itself always runs locally.
