Marketing Claim Evidence Reviewer

Gavin McKew built a reviewer using Jev that reads a marketing site on every PR and identifies sentences making claims without evidence beside them.

Every company writes copy rules. Nobody enforces them after launch week. So I made the reviewer that never gets tired. It reads your marketing site on every PR and names each sentence that makes a claim with no evidence beside it. It's using Jev from @typesafeai It doesn't know your facts. It knows what a claim without proof looks like. https://t.co/bHrzAWVicC @MParakhin don't hate me

The reviewer is intended to enforce copy rules after launch week. It does not know the company’s facts; it identifies what a claim without proof looks like.
