Zup: AI Captions & Posts

Edit photos with Zup AI, write captions in your own voice for every social app, preview every post, and share in a few taps.

Your best photos should not stay buried in your camera roll. Zup turns the moments you choose into polished, share-ready posts while keeping you in control of every word and every share.

Select one photo or a set, then get a caption tailored for Instagram, TikTok, X, LinkedIn, or Facebook. Edit the draft, switch platforms, preview the result, polish the writing, or publish through a supported connected account.

Zup includes:

• Multi-photo selection and an in-app camera • Platform-aware caption drafts for Instagram, TikTok, X, and LinkedIn • Hosted vision captions with explicit permission before sharing with AI services • Google Gemini captions, with compatible AI model choices • Optional prompt-based Zup AI photo editing with undo and restore-original controls • A private Voice Profile for tone, length, emoji, and hashtag preferences • Direct Instagram Feed and Story publishing for supported professional accounts • TikTok publishing and native sharing options • Confirmed direct publishing for connected X, Facebook Pages, and LinkedIn accounts • A native iOS share sheet for other compatible apps • A calm, light glass interface that keeps photos and captions easy to read

Zup never publishes automatically. You review the caption and choose the destination every time. Photos remain local unless you explicitly authorize hosted captioning or photo editing, or choose to share a post with a social network.

Some sharing options require the destination app or an account with that service. Apple on-device captioning availability depends on the iPhone model, language, and system configuration.
