Capture ideas with Speech to Text, revisit edits with Version History, and export documents to Word or PDF to share or keep writing. Designed for Writing • Switch between Source, Focus, and Live modes — Markdown users can type raw syntax directly, while everyone else gets a WYSIWYG experience just like a regular document app • Use headings, bold, italics, inline code, quotes, lists, and to-do lists • Insert links, dividers, tables, image references, and language-tagged code blocks • Undo, redo, document outline, and code syntax highlighting are all supported Plain Text, Too • Create .txt documents and write in a lightweight editor with no syntax markers and no formatting tools • Renaming, find and replace, and sharing are all still there Speak Your Ideas • Use Speech to Text to write directly in Markdown or plain text documents • Choose a recognition language, and pause or resume whenever you need Revisit Your Edits • View before-and-after changes in Version History and choose the content to restore • Lock important versions to prevent automatic cleanup Organize Your Library • Create folders and nested folders • Jump back into what you're working on via Recents • Add notes, sort, move, rename, or batch-manage items • Deleted items go to Trash first and are kept for one month Take Control of Files and Display • Export documents or folders as Markdown, TXT, Word, or PDF — easy to share, print, or continue editing in other software • Customize font, font size, default editing mode, and save behavior • Follow system appearance, or choose Light or Dark theme • Available in 28 languages Extra Access Protection If needed, you can add in-app access verification to specific folders using a password, Face ID, or Touch ID. Face ID / Touch ID verification is handled entirely by the system — the app itself never accesses or stores your facial or fingerprint data. This feature does not modify or encrypt the files themselves. Your words, clear, focused, and in your control.

After the trial ends, your subscription will automatically start and renew at the price shown on the page.
