Still from the clip posted with this case; watch it in the original post on X.

Built a Chrome extension that fills 15 form fields in 1.2 seconds using Jev for the input decisions.

The original post, translated

【Entering 15 fields completed in just 1.2 seconds】 I've always thought, "Why do I still have to type everything else manually when there's autofill for account information?" for tedious form entry. So, I tried making my own Chrome extension using the talked-about TypeSafe AI "Jev"... and I'm amazed by its unimaginable speed.

【15項目の入力が、わずか1.2秒で完了】面倒なフォーム入力、アカウント情報の自動入力はあるのに「他はなんで手入力のままなの？」とずっと思っていました。そこで、話題のTypeSafe AI「Jev」を使ってChrome拡張機能を自作してみたのですが……想像を絶する爆速で感動しています。

Numbers are a snapshot taken from X when the case was added to the library (schema v1, collected 2026-09-19); they will not match today.

Where this case fits

Filed under browser & computer use. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the browser & computer use page.
