One shortcut. Four ways to get unstuck.

Lumen is an AI assistant that reads the screen you are on. Pick the tool that matches what you are stuck on.

  • Summarise

    An AI summarizer for PDFs, articles, and long documents

    Lumen reads the page you are already on and returns the key points, the definitions that matter, and the conclusions - with the fluff removed.

    PDFs · Articles · Docs
  • Solve

    A coding debugger that answers with the fix

    Highlight a stack trace or a broken function. Lumen finds the root cause and hands back the corrected code, ready to paste. Maths and formulas work the same way.

    Any Editor · Any Language
  • OCR

    Text extraction that runs on your device

    Text locked in an image becomes copyable text. Lumen recognises it locally, so it stays accurate on small type and never has to be sent anywhere to be read.

Code and errors

Highlight a stack trace, syntax error, or broken function and get the exact fix, ready to copy and paste.

Stealth Mode

Keep Lumen out of your screen shares and recordings entirely, without turning the overlay off.
