## What is Etona?

Write anything. Etona connects it.

The idea in the shower. The wine you liked. Where you parked. A link you already saved twice. Nothing is too small, and nothing needs a title or a folder. Write it as it comes. When you look back, Etona has found the themes running through your notes, and it answers from them, showing the note each line came from.

FREE TO WRITE
• Capture from anywhere: the Lock Screen, Control Center, the iPhone's Action button, and Share in any app.
• Saves on your device first, instantly, online or not. Nothing waits on AI.
• Notes, links, photos, screenshots, voice memos and files. Etona reads the words in your photos, PDFs and voice memos on your device.
• Search by a word, a name, or what you meant.
• Write in any language. Search and names were tested in English, Korean, Japanese, Chinese, Arabic and Hindi.

CONNECTED, WITH ETONA PRO
• Themes: notes that belong together find each other, each theme in its own color, like "Friday the Dog" or "Japan trip".
• Theme pages: what your notes say about a theme (what you know, what changed, what's still open). Every sentence has a number. Tap it to open the note it came from.
• Ask: ask a question in plain words. Etona answers from your notes and quotes the one it used. If your notes don't say, it tells you.
• Your week: the last seven days, told back as a short story in your own words.
• Sky: every note as a star, grouped by theme, in 3D.

ON IPHONE AND IPAD
• One account, and your notes on both. On iPad, your notes sit in a sidebar beside the one you're reading.

YOU'RE IN CHARGE
• Everything Etona finds is marked until you keep it. Rename or hide anything, wherever you see it.
• Bring your notes: Etona reads exports from Apple Notes, Obsidian, Evernote, ChatGPT and Claude, and Markdown and text files.
• Take everything with you as Markdown, with your theme pages and names, any time, free.
• Turn AI off in Settings and nothing goes to Google's Gemini. Delete your account there too, and your notes go with it.

WHERE YOUR NOTES GO
Every note saves on your device first. Search, reading the words in photos and PDFs, and transcribing voice memos happen on your device. Your notes back up to our cloud. If you allow AI, the text of your notes goes to Google's Gemini AI through our server, to find names and themes and to write pages, answers and Your week. Under the paid terms we use, Google doesn't train its models on it. No ads, no tracking, never sold.

WHY "ETONA"
