Fact checker for journalists: check claims against current web sources

Paste up to five claims. Byline searches current web sources for each, gives a verdict with its reasoning and lists the links, so you can verify before publishing.

How it works

Open Fact Checker in your workspace and fill in what you know. Rough notes are fine; required fields are marked.

You giveExample
Claims (one per line) Enter each claim on a new line: The government allocated $850 million to health 3.2 million people live with HIV in the country The currency fell 40% this year
Context (optional) (optional) 2026/27 national budget debate, Ministry of Finance

Press Write and the result appears as it is written.

How to use the verdicts

  • Treat each verdict as a lead to check, not a final ruling.
  • Open the source links and confirm with the original documents.

Accuracy first

Byline writes only from the facts you give it. It never invents quotes, sources or figures, and when something important is missing it marks the gap, like [CHECK: name of the spokesperson], for you to fill. You check every fact before publishing.

Questions

Is the fact check final?

No. It speeds up checking; the journalist confirms with primary sources.

Is the Fact Checker tool free?

It is included from the Solo Journalist plan. New accounts get a free trial with every template.

Which AI models can I use?

You can choose Claude, GPT, Gemini, Llama or Mistral, depending on your plan.
