About Filtir

AI-assistants like ChatGPT offer tremendous benefits for content authors.

But there's a catch.

They "hallucinate" factual claims that are demonstrably false.

Filtir is a fact-checking ChatGPT Plugin (also available as a web app).

Filtir works by assessing whether there is public, auditable evidence to support the claims identified in written body of text.

When a claim lacks support, we let you know.

Frequently Asked Questions

How do you determine whether a factual claim is true?
We do not arbitrate truth. Instead, we provide evidence in support of factual claims made by a piece of text. Where we are unable to identify appropriate evidence, we flag the claim as "unsupported". This does not mean that it is not true, it simply means that we cannot readily find public evidence in support of the claim.

Which sources of evidence do you consider acceptable? How do you know if a source is "trustworthy"?
Our objective is to provide supportive evidence where we can find it. At present, we do not discard evidence based on reputation metrics - instead, we trust the user to make an assessment. However, we will be working closely with our users and may revise this strategy in future if we learn that a different approach better serves user needs.
