Claim extractor

When to use it

Before you buy from, sign with, or repeat something you read: a sales page, a job ad, a pitch deck, an article or a webinar transcript.

The prompt

Fill in the parts in square brackets, then paste it.

Paste this in

You help me find the factual claims in a piece of writing so I can check them. You extract claims; you don't judge whether they're true.

Below is [what it is: a sales page, an article, a pitch, a webinar transcript] from [who published it, and when].

Pull out every checkable factual claim about [the topic, company or product]. Skip opinions, slogans and predictions ("the best in the region", "will change everything").

Give me a table with these columns:
1. Number
2. Exact quote, copied character for character. Never paraphrase or tidy it.
3. The claim in one plain, neutral sentence
4. Type: price, performance, customers, credentials, legal, or other
5. Could it be checked against a public record? Yes or no, and which record
6. How sure you are that this is a factual claim, not an opinion: high, medium or low

If there are no checkable claims, say "none". That's a fine answer. Don't add claims that aren't in the text.

The text:

Then send something like this

A first message

Below is the home page of a bookkeeping service called Tidewater Books, copied today from their website: "Trusted by over 2,000 small businesses across New England. Our certified team catches 99% of errors before tax time. Rated number one by Coastal Business Review. The friendliest bookkeepers you'll ever meet. Plans start at $79 a month, no contract."

Be careful

A claim on the list isn't true or false yet. It's a list of things to check.
Use your browser's Find (Ctrl+F or Cmd+F) to confirm each quote appears in the original word for word. If it doesn't, don't trust the claim built on it. See Confident is not correct.
Paste only public text, or text you're allowed to share.

Then check the quotes

AI sometimes tidies or invents a quote. In the same chat, ask it to show where each one came from. Anything marked not found gets dropped until you've checked it yourself.

Second pass, same chat

For each quote in your table, show the full sentence before and after it from the text, exactly as written.
If you can't find a quote word for word in the text, write "NOT FOUND" for that row. Don't repair or rebuild it.

Where to paste it

Menus change, so look for the words below rather than an exact path. Saved once in one of these places, the prompt applies to every new chat there.

ChatGPT: For every chat, look for custom instructions in settings, often under personalisation. For one piece of work, look for Projects and the project's instructions. If your plan lets you make your own GPTs, look for creating a GPT and paste it in as its instructions.
Claude: For one piece of work, look for Projects and the project's instructions. For every chat, look for personal preferences in your profile or settings.
Gemini: Look for Gems: make a Gem and paste it in as its instructions. For facts about you that every chat should know, look for saved info in settings.
Copilot: Look for custom instructions or personalisation in settings, where your version has them. Where it doesn't, paste it as the first message of a new chat.

Any assistant, any plan: start a new chat, paste the prompt as your first message, then send your request.
