DescribeThat

DescribeThat is a productivity tool that turns photos and PDFs into structured data using your own Claude key. DescribeThat is a free web tool that extracts structured details from photos and PDFs, including people, objects, vehicles, text and scenes. It runs on Claude Sonnet 5 through the user's own Anthropic API key, stored only in the browser.

DescribeThat is a free extraction tool from Iacoletti Software that reads photos and PDFs and returns structured information about what they contain. According to its listing, the output covers people, objects, vehicles, text and finer scene details, so a single upload can produce a broad inventory of everything visible or written in a file. The version shown on the homepage is 5.2, and the engine behind it is Anthropic's Claude Sonnet 5. The tool runs on a bring-your-own-key model. On opening the app, a visitor is asked to paste a Claude API key, which can be created for free in the Anthropic Console. The key is saved locally in the browser and, as the page states, does not leave the device. Before the interface unlocks, the key is verified with Anthropic. Until that step is completed the app shows a "System Restricted" notice and keeps the extraction engine switched off. Help, license and privacy links sit beneath the key form. In practice this suits people who need to turn unstructured visual material into organized notes: researchers cataloguing images, analysts reviewing scanned documents, investigators or administrators who want a detailed written breakdown of a photograph, or anyone who wants text pulled out of a PDF alongside a description of its visual content. The homepage does not describe export formats, batch limits or output schemas, so those details would need to be checked inside the app. Among alternatives, DescribeThat sits between general chat assistants that accept image uploads and dedicated document OCR or data capture platforms. It is narrower than a full document automation suite and has no visible integrations, but it removes subscription cost from the tool itself. The cost that remains is the usage billed by Anthropic against the user's own key, which makes it a lightweight, transparent option for occasional or technical users comfortable managing an API credential.
