Claimlight checks factual claims as you write, shows what current evidence supports, and helps you correct only what needs correcting.
I understand why people are skeptical.
NASA reported that 2024 was the hottest year on record. That means climate models have never been wrong.
We should take the evidence seriously without overstating it.
Climate models carry real uncertainty; their projections have been both accurate and inaccurate across metrics.
From draft to evidence
A finished sentence becomes a researchable claim. Claimlight traces the evidence, then gives the decision back to you.
Write naturally. Claimlight notices completed sentences that make factual claims.
See whether evidence supports, contradicts, or complicates a claim—and inspect the sources behind each verdict.
Accept the smallest correction in your voice, add a citation, or leave the draft as it is. You remain in control.
Sources, not verdicts from nowhere
Every decisive verdict links to attributable evidence, with source context you can read for yourself.
