Building in public
How we built the quality gate
A model can write product copy, but someone else should decide whether that copy is ready to publish. In Mimir, a two-stage gate does that job.
Mimir team
Mimir writes product copy in the language of the market you sell in, in your brand voice. Writing is the easy part. The hard part is catching certain copy before it goes live: copy written in the wrong language, copy with passages left untranslated, and copy that adds a number the source doesn't contain.
Stage one: rule checks
The first stage runs rules, not a model. It rejects copy in the wrong language, sections left untranslated, and any number that isn't in the product source. Rules return the same result every time, so the same copy always gets the same verdict. Whatever the gate finds is passed to the second stage as notes, and corrected copy goes back through the gate.
Stage two: a native-speaker editor
A second model reads the copy together with the gate's notes and asks one question: would this read naturally to an editor who speaks the language natively? A rule can confirm “right language, right numbers.” Only a reader can judge tone and flow.
Passing the gate still means waiting for approval
Copy that clears both stages doesn't go live. It sits as a draft, waiting for your approval. The gate is there to sort the pile that lands in front of you, not to take the decision away from you.
