Nudge is a private journal and diary app for Windows that works 100% offline. Write a daily journal, lock it with Windows Hello, and let an optional AI companion that runs on your own PC ask the gentle question that keeps you writing. Try every feature free for 15 days. Your thoughts belong to you, not to the cloud. Nudge needs no account, shows no ads and collects nothing. Every entry is a plain Markdown file in a folder you choose, so your diary stays readable for life, with or without Nudge. 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. • Mood check-ins, tags, voice memos, sketches, quick capture and time capsule letters to your future self. • Kind insights: what you write about, when you write and how your mood moves, with streaks that forgive a missed day. FIND AND KEEP EVERYTHING • Fast search across every entry, a timeline, a calendar and On this day memories. • Import from Day One, Obsidian, Markdown folders or CSV. Export to Markdown, HTML or a printable book. • Several journals side by side, and revision history for every entry. • 49 interface languages, including right-to-left scripts. Write in any language you like. FREE 15-DAY TRIAL Try every feature free for 15 days. After that, Nudge is a one-time purchase through the Microsoft Store: no subscription, no add-ons, no ads. If you decide not to buy, the entries you wrote stay readable, searchable and exportable.
