    Frequently asked questions

    App Preview Kit uses Jina Reader to extract the text content of your product site — feature descriptions, benefit statements, testimonials, pricing context. This content is passed to the caption model with your app category and target audience as context. The output is captions that reference your actual feature names, not placeholders like 'Feature 1: Fast performance'.

    Yes. You can paste a PDF product brief, an App Store listing URL from a previous version, or type a freeform description directly. The URL input is the fastest path, but the caption model works from any text description of your app.

    Yes. Before export, a claim classifier reviews every caption for unverifiable superlatives ('world's best,' '#1'), competitor name-drops, and pricing statements that differ from the listed App Store price. Flagged items are highlighted in the editor with a suggested rewrite — you can accept the suggestion or override it.
