Why one sentence matters this much
When an AI engine answers "what is [brand]?" or "best tool for X", it doesn't paraphrase your whole homepage - it lifts a sentence. If your site never states plainly what you are, who it's for and what it costs, the model guesses, hedges, or quotes a competitor's clearer page instead.
Where to put it
Paste the sentence, in plain text, where crawlers and models read first: your homepage hero, the intro of your docs, and near your pricing table. Mark the page up with schema so the facts are machine-readable too, and drop the same line into your llms.txt.
Keep it factual
No superlatives - "the best" and "leading" get discounted. Category, audience and price are the facts a model can safely repeat. The duller and truer it reads, the more likely it gets quoted verbatim.
