Caption Hero is a local-first Windows app for turning messy image folders into searchable, organized libraries. It uses local AI to generate captions and tags, find duplicates, and search by meaning instead of filenames. Process single images or batches, browse everything visually, and export a catalog for advanced AI-agent workflows. Your images stay on your machine. No cloud image processing required.
Hey Product Hunt — I’m the solo dev behind Caption Hero.
I built it because I had a ridiculous number of image folders and got tired of manually digging through them every time I wanted to find something.
Caption Hero runs locally on Windows and uses local AI to caption, tag, search, dedupe, and organize image libraries. It can also export a catalog that you can hand off to an AI agent for more advanced workflows.
The privacy angle mattered a lot to me: your actual images stay on your machine.
I’m still early, so feedback is genuinely useful — especially bug reports, confusing UX, or anything that feels unnecessary.
I also made a 20% Product Hunt launch discount for the first 30 days.
Thanks for checking it out.
