Minimal white card with a claim under review and muted Supported, Unclear, and Unsupported labels on a quiet gray-white canvas.

Bring the claim and the evidence

News fact-checkers judge public statements against published reporting. This fact checker is for your draft: paste the exact sentence under review plus quotes, data, or notes you already trust. Empty “is this true?” prompts force guesses. For long background reading first, use the PDF Summarizer or Text Summarizer.

Single white result card with four plain fact-check sections and short bullets on a soft off-white background.

Sort claims by evidence strength

Ask for supported facts, weakly supported lines, missing context, and open questions in separate lists. That structure makes revision faster than a single yes-or-no answer and mirrors how editorial teams review launch copy. Sharper review prompts follow How to Write AI Prompts That Actually Work.

Two quiet white cards comparing an overstated claim with strikethrough and a cautious rewrite on a pale gray canvas.

Rewrite without hiding uncertainty

Request cautious alternatives that preserve the useful point while removing overstated numbers, universal language, or unnamed sources. You remain responsible for what ships. Before publishing, align final copy with the Press Release Generator or Headline Generator if needed.

What you can do with Ottermind

Frequently asked questions

What does this fact checker do?

It helps you review a claim or draft against the sources you provide, then sort supported facts, weak evidence, missing context, and safer rewrite options. It is a review aid, not a guarantee of truth.

Is this the same as Snopes or factcheck.org?

No. Those sites evaluate public claims against published reporting. This page helps you review your own draft copy against the evidence you supply in the prompt.

Can it browse the web to verify everything?

Treat this page as working from the claim and evidence you supply in the prompt. If you need live source checks, add those findings to the prompt before you ask for a review.

Will it always say true or false?

Often the useful answer is more nuanced: supported, unclear, or unsupported with reasons. Ask for structured output instead of a single verdict when the claim depends on context.

Can it replace editorial or legal review?

No. It helps you spot risky claims faster, but final responsibility for published statements remains with you and your review process.

What should I do after fact-checking?

Apply the cautious rewrite, then continue with the Press Release Generator, Headline Generator, or AI Email Generator as needed.
