New: 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, model-specific permission
• Gemini 3.7 Flash as the default TokenRouter model, with compatible 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.
Zup makes posting photos so much easier. I usually get stuck trying to come up with a caption, but here I can just add a little context about the photo and it gives me something that actually sounds natural. I also love being able to quickly adjust the tone depending on where I’m posting. Simple, fast, and genuinely useful.

I can now post in the moment
Swipe back smoothly from Compose and Your Voice with native iOS navigation. Larger photo sets now compress only when needed, making caption generation and publishing more reliable while preserving normal quality for requests that already fit. Instagram now shows direct posting only when an account is connected and keeps a clear caption-copy fallback available to everyone.
