TextUnbox
TextUnbox runs printed and handwritten OCR, DALL-E image generation, speech-to-text, translation, and background removal from one web portal and a shared REST API. Upload or paste an image in the browser to extract text, generate visuals from a text prompt or voice recording, transcribe WAV audio, or strip a photo background. A single license key unlocks every browser app and API endpoint, with usage counted per successful operation rather than by monthly seat.
Most OCR tools stop at text extraction, and most image generators ignore document scanning entirely. TextUnbox ties both workflows to the same prepaid unit pool, so a team can OCR a batch of receipts and generate marketing art without buying separate subscriptions. The REST API at hello.textunbox.app accepts multipart image uploads and JSON prompts, with OpenAPI specs and Postman collections published on the docs site.
Developers building document pipelines, mobile capture apps, or internal automation can call standardized HTTPS endpoints with an x-textunbox-licensekey header. Casual users get the same capabilities through responsive browser pages, including clipboard paste for quick scans. Free trial keys are available by email without a credit card, though ongoing use requires buying prepaid extraction units through Gumroad.
