How to find where an article says something in Chrome
The short answer
When Ctrl+F fails because you remember the idea but not the wording, ask ProofJump's side panel "where does this article say …?" — it anchors the answer to the exact sentence and jumps you to it, highlighted in place. If the article never actually says it, you get "no source on page" instead of a stretch.
- 1
Open the ProofJump side panel on the article.
- 2
Ask where the article says the thing you remember, in your own words.
- 3
Click the citation to jump to the exact sentence, highlighted in the page.
- 4
Step through next/previous if the point is made in more than one place.

If it's flagged "no source on page", the article doesn't say it — don't cite it.
You're sure the article said it — that the trial was unblinded, that the feature is deprecated, that the deadline moved. But Ctrl+F comes up empty, because find-in-page matches strings and you remember a meaning. Here's how to find the sentence in Chrome by asking for the idea, and how to be sure when the article genuinely never said it.
Why find-in-page keeps failing you
Ctrl+F needs the author's exact words. If the article says "participants were aware of their assignment" and you search "unblinded", you get nothing — not because the claim isn't there, but because you and the author phrased it differently. The longer the article, the worse the guessing game gets.
Ask for the claim instead
Open the ProofJump side panel on the article and ask directly: "Where does this say the trial was unblinded?" ProofJump reads the page's own text — only that page, only after you invoke it there — and looks for the passage that actually supports the claim, however it's phrased.
Jump to the exact sentence
The answer comes back anchored to a verbatim quote. Click it and Chrome scrolls to that sentence and highlights it in the original text, without modifying the page. If several passages are relevant, step through them with next and previous — useful when a claim is built up across sections rather than stated once.
Trust the "it's not here"
The more valuable result is often the negative one. If the article never actually says what you remember, ProofJump flags the claim as "no source on page" rather than stretching a vaguely related sentence to fit. That's exactly what you want before you quote, cite or repeat something: confirmation that the source says it, or a clear signal that it doesn't.
Where the lookup runs
You choose the processing path in settings: on-device AI where your Chrome supports it (the article's text never leaves your machine), your own OpenAI, Anthropic or Google API key (sent directly to the provider, not through ProofJump's servers), or the Pro cloud. An optional local redaction switch replaces emails, phone numbers, card numbers and tokens with placeholders before anything is sent over the network — the matching back to the page always happens locally.
When to still use Ctrl+F
If you know the exact wording — a name, an error code, a quoted phrase — find-in-page is instant and unbeatable. Reach for ProofJump when you're searching for a meaning rather than a string, or when "not found" needs to mean "the article doesn't say it" rather than "I guessed the wrong words".
