New in v5.0.0: • AI writing assistant: tap ✨ in any note to summarize it, pull out the key points, turn it into bullet points, fix spelling and grammar, or finish a half-written thought. • Tone & translation: rewrite a note in a formal, friendly, kind or playful voice, or translate it into any of 14 languages. • Works on your selection: select a passage and only that part changes. Replace the note with the result or add it to the end — and undo it if you don't like it. • Title & tag suggestions: stuck for a title? Get three, plus tags that fit the note. • Your own commands (Premium AI): "Turn this into an email", "sort by date", "keep only the numbers"… whatever you can think of, applied to your note. • Privacy first: only the text you're working on is sent. Locked notes are never sent, and you can exclude any note from AI entirely. • Transparency: everything the AI writes is marked, and you see how much of your allowance an action will use before you run it. • Try the writing assistant a limited number of times with a free account. You don't need an account to take notes or keep a journal — the app works fully offline. Signing in is only needed for cloud sync and AI. More highlights: • Journal mode: your days on a calendar, a page for each one, a timeline and a gallery of the days with photos. Free on your device, cloud sync with Premium. • Writing prompts & streak: a question for the days you don't know what to write, themed packs, and a count of the days you write in a row. • Mood tracking: log your day with one tap. Monthly summary free, month-by-month trends with Premium. • On This Day: read what you wrote a year ago today. • 5 retro color palettes to make the notebook yours — all free. • Cloud sync: keep your notes identical on every device. • Note version history: last 3 versions free; 30 days of history and side-by-side comparison with Premium. • Share links: share a note through an open or password-protected link (Premium). • Backups: free to your device as JSON or PDF; a cloud copy and the full history with Premium. • Focus Mode: write on a clean, full-page screen. • Checklists for to-do and shopping lists, multiple tags and pinned notes. • Rich text: bold, italic, underline, strikethrough, collapsible headings and lists. • Add images, drawings, links and voice notes to any note. • Reminders, home screen widgets and ready-made templates (Meeting Notes, Shopping List, Recipe). • PDF export: turn one note or all of them into a notebook-style PDF (Premium). • Lock the app with a password or fingerprint; lock individual notes with Premium. • Advanced search: filter by date, tag, category and attachment type. • Document scanning (OCR): photograph text on paper and turn it into editable text. • Trash, list or grid view and colorful categories; font size, color and typeface are up to you. • Tablet layout: your list on the left, the open note on the right.
