A developer has launched Online OCR Free, a browser-based tool for batch processing documents using Tesseract and AI models from Google Vision, Gemini, and OpenRouter. The platform addresses a gap for users needing free batch OCR capabilities without subscription fees or markup on API usage. Users provide their own API keys for premium services while Tesseract runs locally at no cost.

Built for handling large document sets, the tool supports export formats including TXT, JSON, XML, and PDF. AI engines allow custom prompts for tasks like translation, form field extraction, and structured output generation in a single step. The interface handles multi-page PDFs, batch uploads, and column-based layouts with preprocessing for improved recognition quality.

Available at onlineocrfree.qzz.io with source code on GitHub, the tool supports over 60 languages including Bangla with specialized character correction. Users can process multiple files simultaneously, configure concurrent threads, and receive results via email. No account creation is required as preferences are saved locally in the browser.
