Metadata Reactor

Metadata Reactor is an image generator tool. AI metadata generator that reads an uploaded image and writes titles, tags, descriptions, captions and hashtags for eleven platforms including YouTube, Etsy, Adobe Stock, Amazon and Shopify. Fields are editable and export to TXT, JSON, CSV or PDF, with batch runs of up to 50 images.

Metadata Reactor is a metadata generator built around image analysis. Instead of writing from a text prompt, it reads the visual content of an upload (subject, style, colors, mood) and produces the titles, descriptions, tags, keywords, captions and hashtags that a specific marketplace expects. The supported destinations are YouTube, Etsy, Amazon, Adobe Stock, Shopify, Pinterest, Instagram, TikTok, X (Twitter), Facebook and Redbubble. A single upload can feed all eleven at once, returning more than 50 fields, and the vendor puts the turnaround at under a minute per image. The practical case is volume. A stock contributor keywording a hundred files by hand is looking at a long day; Adobe Stock alone allows up to 49 keywords per image. An Etsy seller has a 13-tag ceiling to fill and a listing title that has to read naturally. Print-on-demand artists republish the same design across Redbubble, Amazon Merch and similar channels. Metadata Reactor collapses those repetitive jobs into one pass, and it enforces each platform's field limits so the output can be pasted into a listing editor without trimming or reformatting. Batch runs handle up to 50 images at a time. Every generated field stays editable in place, and results can be copied to the clipboard or exported as TXT, JSON, CSV or PDF. That matters because the tool drafts rather than publishes: the seller reviews tone and accuracy before anything goes live, and the output is treated as the user's own listing copy, the same as text typed by hand. The site is candid that its advantage over a general chatbot is the image reading and the built-in field rules, since a chatbot writes from whatever words it is handed and ignores platform caps. The audience is sellers and creators who publish the same asset in several places: Etsy shops, stock portfolios, print-on-demand catalogs, YouTube channels and social accounts. It is the least useful for someone with a single listing on a single platform, where hand-written copy and a keyword tool cover the job. The free tier removes the signup barrier, and pricing scales with monthly listing volume rather than seats.
