RedLetter
PDF-first reading survival app
Upload
Bring your reading into RedLetter your way.
Version 1 now supports two equal input paths: Upload PDF for standard reading files, or Paste Text for copied material from phones, notes, or anywhere else you can grab the words.
Bring in your reading
Choose the input path that matches what you already have. PDFs and pasted text are both first-class ways to start RedLetter.

RedLetter should treat the uploaded PDF like the center of the app, not just a file attachment. This flow starts that handoff.

Before you start
Upload a PDF and let RedLetter extract the reading, build context, and open the reader flow.
