Features

Everything Nudge does

PRIVATE BY DESIGN

  • No account, no sign-in, no ads, no telemetry.
  • Diary with lock: unlock with Windows Hello face, fingerprint or PIN, and hide the page when you step away.
  • Encrypted backups (AES-256) that you can restore at any time.
  • Nudge works without the internet. The only download is the optional AI companion model, once, if you want it.

AN AI COMPANION THAT STAYS ON YOUR PC

  • A gentle opening question for a blank page and short follow-up questions when you pause. No advice, no judgement.
  • Ask your journal in plain words, for example "What have I written about sleep?", and get an answer that cites your own entries.
  • A weekly synthesis and reflective lenses, all written on your device.
  • Entirely optional: with the AI switched off, Nudge is a complete journal with a bank of human-written writing prompts.

A JOURNAL YOU WILL KEEP WRITING

  • Distraction-free editor with focus mode, typewriter mode, light and dark themes.
  • Guided journeys: six multi-day programs of daily writing prompts, plus templates for gratitude, morning pages, daily reflection and weekly review.
