Supremo AI vs PDF Reader & Tools

Local LLM chats that run & stay on your device

PDFKit is the privacy-first PDF reader and toolbox that does everything on your device — no uploads, no accounts, no waiting in line. Open any PDF and read it like a book, with paginated turn animations, sepia/dark backgrounds, font-size and line-spacing controls, bookmarks, and highlights that sync across reading sessions. Or stay in classic document mode for forms, contracts, and reports. Then jump straight into the toolbox: merge multiple PDFs, split a single document by page range, compress a giant scan to email size, convert images to PDF (and PDF pages back to images), rotate, reorder pages, add a password, watermark a draft, or stamp page numbers. Every operation runs locally — your files never leave your device.
