Turn your photos into captions in your voice for social media
A free iPhone app that generates editable social media captions from photos, with AI assistance and support for five platforms.
About this launch
Zup is a free iPhone app that helps you create social media posts from photos. Start by selecting a photo from your camera roll or writing an idea, then generate an AI-assisted caption in one of six tones: Natural, Heartfelt, Playful, Bold, Storytelling, or Polished. You can edit the caption to match your voice, adjust the length and hashtags, and apply photo editing tools like cropping and filters. Before sharing, preview your post on any of five supported platforms: Instagram, TikTok, X, LinkedIn, and Facebook. You have final control—Zup only publishes after your confirmation. For X and LinkedIn, you can schedule posts up to 30 days in advance. The app requires iOS 18.0 or later and is completely free to download and use.
