Nexiant Scribe is a free, local content editor (free-of-charge, closed source — see LICENSE). Read documents and any PDF, leave comments and annotations, and hand the marked file to anyone — no account, and opening a file uploads nothing.
This page is the reader itself, and it needs JavaScript.
Drag in a PDF, image or .zip document set. Page through it, search the text layer (OCR included for scanned sheets), draw markups — text, shapes, stamps — attach notes and RFI-style comments, and export a marked PDF that opens in any reader.
