Local by default

Reading, search, editing, forms, and signatures stay on your device. AI is optional and only runs when you ask.

Light & Dark

Switch between themes to match your preference.

Readlet AI

It reads with you.

Ask about a sentence, a visual detail, or the whole document. Readlet brings the relevant pages into the conversation and keeps every answer anchored to its source.

  • Understands text, page images, handwriting, and your edits
  • Shows page references without interrupting the answer
  • Keeps separate, locally saved chats for each document

The reader works without Readlet Companion.

Companion is only needed for Readlet AI. It connects the extension to your existing ChatGPT account, checks for its own updates, and can be removed without affecting the core PDF workspace.

About Companion
The little things

Polished in the details.

Thoughtful interactions that keep the interface out of your way.

Smooth at any scale

Trackpad, mouse, touch, and pen gestures stay anchored to the content beneath you, even through fast zooming and long pages.

Page-by-page control

Rotate, duplicate, remove, reorder, or export an individual page without disturbing the original document.

Search without waiting

Results appear progressively, group themselves by page, and stay keyboard-navigable while local OCR handles scanned text.

Comfortable in every theme

Choose light or dark, then let Ambient Mode borrow subtle colour from the page when you want the document to set the atmosphere.
