Recent updates and features
A preset now controls whether keywords, the stock title, and your IPTC profile are written at all — so "Client Delivery" delivers exactly that. Stock titles also survive XMP-sidecar exports for RAW shooters, iPhone sharing sends the photo and its caption together, and error messages finally say what went wrong in plain words.
Caption unlimited photos free with a local Ollama model on your Mac — your photos never leave your machine. Plus a free taste of Stock Mode and a first-run sample batch to try before importing anything.
Stock mode now writes a short agency title and a full description to their own metadata fields — matching what Adobe Stock, Shutterstock, and Getty each expect.
No API keys needed! Subscribe and start captioning instantly on both macOS and iOS. Choose from Basic, Pro, or Unlimited plans.
13 professional presets including Stock Commercial, Real Estate, Food Photography, Travel, and more. Create custom templates on macOS and iPad.
Automatically extract location data from photo EXIF and incorporate it into captions. Perfect for travel and landscape photography.
Optimized presets for Shutterstock, Adobe Stock, and Getty Images. Includes compliance validation for editorial vs commercial content.
