CaptionSmith turns the tedious work of captioning and keywording into a few taps. Point it at your photos, pick a style, and let AI write professional titles, descriptions, and keywords — then embed them straight into your image metadata, ready for stock agencies or your own searchable library. Built for stock photographers, and just as handy for everyday photos. WHAT IT DOES • AI captions & keywords — Claude, OpenAI (GPT), and Google Gemini analyze each photo and write accurate, natural descriptions plus 20–45 relevant keywords. • Stock Photography Mode — agency presets for Shutterstock, Adobe Stock, and Getty/iStock with the right keyword counts, title lengths, and editorial formatting. • Compare providers (new) — run one photo through Claude, GPT, and Gemini side by side and keep the caption and keywords you like best. • 13 caption templates — Descriptive, Concise, Stock Commercial, Stock Editorial, Product, Real Estate, Food, Travel, Portrait, Event, Artistic, Social, and a new Family & Everyday style. • People tagging — tag friends and family so their names appear in captions; on-device face detection helps you tag faster (no facial recognition, nothing stored). • Batch processing — caption 100+ photos at once with live progress. Minutes instead of hours. • Metadata embedding — writes to EXIF, IPTC, and XMP so captions are searchable everywhere and upload-ready; XMP sidecars for RAW/DNG. • Compliance tools — agency compliance checks, one-tap auto-fix, and AI-content disclosure for editorial. • GPS-aware captions — optional location context pulled from your photos. • Export to Photos, share anywhere, or import photos straight from other apps. TWO WAYS TO USE IT • Subscription — no API key required, with a free trial so you can try before you subscribe. • Bring your own key — power users can plug in their own Anthropic, OpenAI, or Google key. SUPPORTED PHOTOS JPEG, HEIC, PNG, and RAW/DNG (via XMP sidecar). PERFECT FOR • Stock contributors uploading to Shutterstock, Adobe Stock, Getty, and iStock. • Photographers who need consistent, agency-ready metadata in bulk. • Anyone building a searchable, well-captioned photo library. PRIVACY • Photos are sent only to the AI provider that captions them. • On-device face detection is used only to help you tag — there is no facial recognition, and no face data is ever stored or shared. • API keys are stored securely in the iOS Keychain. Requires iOS 17 or later. Subscriptions auto-renew unless cancelled; manage them anytime in your Apple account settings.
