# Limen

> Limen is an answer engine optimisation (AEO) tool. It reads a website the way
> AI answer engines do — ChatGPT, Claude, Gemini, Perplexity — scores how visible
> the site is to them (0–100, where 80 is the threshold), and explains in plain
> language exactly what to change. Limen scans and scores your own site; it does
> not monitor what AI assistants say about you.

Limen is a service of Temu AG, incorporated in Switzerland. The free check runs
20 checks on a homepage in about a minute, no card required; the visibility score
and re-scanning come with a subscription. The full analysis is
a subscription in two sizes: Solo ($35/month, or $29/month billed $348 yearly)
watches one site with 1,000 credits a month; Duo ($69/month, or $58/month billed
$696 yearly) watches two sites with 2,000 credits in one shared pool. A full site
scan is 75 credits, a Janus question is 5, and both plans carry a cancel-anytime
promise. Janus is Limen's resident guide, who reads a subscriber's own scan and
answers in plain words.
