Storeboard/Apple Intelligence vs Claude

Apple Intelligence vs Claude, measured on a real listing

Storeboard localizes your App Store listing with AI — and you choose the engine. Apple's on-device model is free and runs offline. Or you add your own API key and a frontier model does the writing, billed by the provider at cost. To find out what that choice is worth, we ran the same localization twice on a live App Store listing: 36 languages, the same nine screenshots, the same description, the same checks.

The result, field by field

Each run wrote an app name, subtitle, promotional text, keywords and description for 36 languages, plus a caption and supporting line for every screenshot. "Complete" means every field present and inside Apple's character limits, counted the way App Store Connect counts them.

The copy is the real difference

Both engines read the same screenshots and the same live description for a period-tracking app. Apple's subtitle for the whole run was "Period Tracker" — the app's own name repeated, spending the store's second-heaviest keyword field on words the listing already had. Claude wrote "Cycle & Fertility Companion" — new indexed keywords and an actual positioning — and then carried it coherently into every language:

The same pattern held for promotional text and screenshot captions: Apple's lines are accurate labels; Claude's read like a marketer wrote them, in every script — including correct Devanagari, right-to-left Arabic and Hebrew, and CJK that fits Apple's limits.

Our recommendation

Start free. Apple Intelligence is genuinely useful: 30 of 36 complete languages at zero cost is a better listing than most apps ever ship, and Storeboard's retry button recovers most of the dropped fields.

Bring a Claude key for the listing you'll actually publish. A whole 36-language run costs about what a coffee does, completes every field on the first pass, and the copy itself is a tier better. In Storeboard: Settings → AI, pick Anthropic (Claude), paste a key from console.anthropic.com, and choose claude-sonnet-4-6. The key never leaves your Mac's Keychain, and there is no markup — you pay Anthropic exactly what the run costs.

Method: one free ASO review action plan for a live period-tracking app, applied twice through the shipping Storeboard build on the same Mac — once with each engine pinned. Numbers are from the saved projects, not from logs; character limits verified in UTF-16, the way App Store Connect counts them.
