Read full descriptionHide full description
Turn voice memos into notes you can organize. Zen Slate brings rich-text notes, voice transcription and to-dos together, with camera scanning and Apple Pencil drawing on supported devices. WRITE, RECORD AND SCAN Use headings, bold, italics, quotes, code blocks, highlights and checklists. Add photos, PDFs and files. Record a voice note with on-device transcription, or scan a document with the camera on supported devices. Transcription availability depends on language, device and speech support. NOTES THAT TURN INTO ACTION Keep to-dos alongside your notes. Add a date, reminder, priority or repeat to a task, then see tasks together and plan them on a calendar. Checklists inside a note stay with that note. Optional Apple Reminders integration is off until you choose it. DRAW ON IPAD Sketch with Apple Pencil using pens, markers, a highlighter, eraser, lasso and ruler. Drawings remain editable after you save them. FIND YOUR WAY BACK Organize with nested categories, tags and smart folders. Search your writing, bookmark a note, and link related notes with double brackets. Backlinks show where a note is referenced. BRING YOUR NOTES WITH YOU Import Markdown folders with their structure, tags and dates. Import supported Evernote ENEX, RTF and HTML files. Export your library as JSON when you need it. YOUR DEVICE AND YOUR ICLOUD No Zen Slate account is required. Notes are stored on your device; sync uses your own iCloud account rather than our servers. Supported devices can protect individual notes with biometric authentication. CAPTURE WITHOUT THE DETOUR Use widgets, the share sheet, Shortcuts and Spotlight to reach your notes. Features vary by platform; camera scanning and Apple Pencil drawing require supported iPhone or iPad hardware. FREE AND PRO Start with five slates for free. Pro removes the limit and adds sync, widgets, backup and export. Choose a yearly subscription or a one-time purchase. The one-time purchase does not renew. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel in your Apple Account subscription settings.
