Three Processing Modes
Drop 1–5 reference JPEGs into the sidebar. MetaBrain analyses their visual style and applies consistent keywords and descriptions to every new image.
Create themed keyword sets for your niches — nature, business, lifestyle. The AI automatically picks the best-matching block for each image.
Drop an entire shoot at once. MetaBrain samples up to 8 images, detects the common theme, and generates a shared keyword pool for all files.
The problem
You shoot hundreds of photos.
Tagging them takes longer than the shoot.
Professional microstock photographers spend 3–5 minutes per image writing titles, descriptions, and keyword sets — just to meet stock agency requirements. For a 200-image shoot, that's up to 16 hours of repetitive, low-value work. MetaBrain eliminates that bottleneck entirely.
How it works
01
Drop your files
Drag images or videos directly into MetaBrain. Supports JPEG, PNG, TIFF, WEBP, MP4, MOV and more.
02
AI generates metadata
Gemini AI analyses your content and returns a scored title, description, and up to 50 keywords in seconds.
03
Review and export
Edit any chip, confirm the result, then write metadata directly to your files or export as CSV for bulk upload.
Optimised metadata for all major agencies
Features
Everything a microstock photographer needs
Correction Intelligence
MetaBrain learns from every edit you make. Remove a keyword 5 times and it gets permanently blacklisted — automatically excluded from all future prompts. The more you use it, the smarter it gets.
Write Directly to Files
No copy-paste workflow. MetaBrain writes Title, Description, and Keywords directly into your JPEG, PNG, TIFF, and video file metadata using exiftool — ready for immediate agency upload.
Confidence Scoring
Every keyword is scored 0–100. Green chips are high-confidence factual tags. Yellow are contextual. Red are abstract. You decide what to keep — at a glance, in seconds.
Four Languages
Full UI and AI output in English, Spanish, Portuguese, and Russian. Switch in one click — no app restart needed.
Privacy First
Your images are processed in memory and never permanently stored on our servers. We never use your content to train AI models. No selling your data. Ever.
Multiple Export Formats
Export as CSV (Shutterstock-compatible), XMP sidecar, JSON, or DOCX. Or write directly into file metadata with a single click.
