Your work,grounded in primary sources.
Meet triff
triff (truth-diff) spots the difference between what your content says and what primary sources record.
How it works
triff isolates each factual claim in your content, locates the primary source most likely to record it, and shows you what that source says — alongside your draft.
You decide what to do with the difference.
With triff, you get one of five findings for every claim.
Verified
The primary source confirms the claim.
The receipt is on file.
Delta
The claim and the primary source record different figures.
You see both — and decide which stands.
Conflicting
Primary sources disagree with each other on the same fact.
Make the editorial call with all the records in hand.
Under-specified
Primary sources are clear, but the claim is too loose for one fair comparison.
Tighten the claim so readers know exactly what is being asserted.
Unverified
The evidence isn't conclusive.
Rather than guess, we hand you the sources we found and where we looked.
Every finding tells you exactly where to look. When we can't reach a conclusion, we say so — and show you what we found.
A triff summary is an at-a-glance view of the findings. Example: ////\\~~??- means the run found 4 verified claims, 2 deltas, 2 conflicting, 2 under-specified, and 1 unverified.
triff works where you work.
In your doc, without leaving it.
triff works as a Google Docs add-on. Leave a comment to trigger a verification — findings come back in the same document, no context-switching required.
On the web.
Upload a document or paste the text you want checked. triff returns findings with full evidence for every claim and saves each run to your account — so you can review results, share a report, and return to earlier work without starting over.
Built into your pipeline.
triff can run as part of an automated workflow — verifying content generated by AI systems, flagging claims before publication, or integrating into existing editorial pipelines. If your workflow produces content, triff can ground it.
Slack and CMS integrations are on the roadmap.
Every finding, fully shown.
triff doesn't ask you to trust a verdict. For every finding, you can see:
- The exact primary source consulted
- The data triff retrieved from it
- How that data compares to the claim in your content
- The full reasoning triff used to reach the finding
If something looks wrong, the references are there. triff is built on AI, and AI makes mistakes. Always verify with the provided sources before acting.
