About chunks.md
Drop your files, get clean markdown, feed it to your AI — your files never leave your device.
Why chunks.md exists
Most online OCR tools are cluttered with ads, paywalls, and upload-to-our-servers dark patterns. Converting a PDF to text shouldn't require signing up, watching ads, or trusting a stranger's server with your documents.
chunks.md is simple and to the point. Drop your files, get clean markdown, feed it to your AI. All OCR engines run directly in your browser, so your files never leave your device. No account, no upload limits, no data collection.
Built for turning documents into knowledge — ready for RAG pipelines, vector databases, and AI workflows.
