Just shake.
Then talk.
Shake your iPhone and say what's on your mind. Furu files it as a clean, searchable note, entirely on your phone.
More than a voice recorder.
Furu is a privacy-first iOS app that turns spoken thoughts into a searchable personal knowledge base — entirely on-device. Voice memos give you a pile of audio files. Furu is a thought organizer: a journal that writes itself, growing into notes you'll actually reread.
furu · 振る
verb, Japanese
to shake, to wave. The only gesture between a passing thought and a kept one.
It writes the notes for you.
You ramble. Furu edits. On-device intelligence turns raw voice into a titled, tidy note the moment you stop talking.
- Word-for-word transcript, cleaned into a readable note.
- Automatic tags for topics, people, and places.
- A title it picks itself. No more "New Recording 47".
Every thought, instantly found.
Furu is your brain vault. That idea you mumbled on a walk six months ago is one search away. Look things up by what you said, who you mentioned, or where you were.
- Full-text search across every word you've ever said.
- Browse by person or place: everything you noted about Dana.
It catches the to-dos you didn't write down.
Say "I need to send Alex the contract" or "meeting with Dana Friday at 3" and Furu notices. Detection runs on-device — the entry goes straight into your own Calendar or Reminders, never a Furu server.
- Events go to your Calendar, one tap.
- Tasks go to Apple Reminders.
- Smart follow-ups nudge you at the right time.
Nothing ever leaves your phone.
Your brain vault stays in your pocket. Transcription and AI run on Apple Intelligence, on your device. No cloud processing, no account, no one reading your notes. Including us.
Don't take our word for it.
What early testers say about thinking out loud with Furu.
“I shake my phone at red lights, on trails, in elevator lobbies. Every stray thought actually gets kept now.”
“The transcript is cleaner than what I would have typed. It even titled the note better than I would have.”
“Finally dropped my $8-a-month recorder app. Furu organizes everything and nothing ever touches a server.”
“It's my brain vault. Six months of walking thoughts, all searchable in a second.”
“I say a messy ramble, it files a tidy note under the right people and places. Magic that respects me.”
“With ADHD, the shake gesture removes every step between thought and note. Genuinely life-changing.”
“Bought it once. Works offline, on a plane, in a tunnel. That's the whole pitch, and it delivers.”
“My best ideas used to die in the shower. Now they're tagged and waiting for me at my desk.”
“Voice Memos gave me 200 files named 'New Recording'. Furu gave me a personal knowledge base.”
“Our Kyoto trip journal wrote itself. Every place we mentioned along the way became a tag.”

Fair questions, straight answers.

Yes. Recording, transcription, summarizing, and tagging all run on your iPhone with Apple Intelligence. Airplane mode changes nothing.
Which iPhones are supported?
Furu needs Apple Intelligence: iPhone 15 Pro or newer, running iOS 26.

Yes — Furu is free, forever. Unlimited notes and every on-device AI feature, no time limit and no feature cut short. A one-time $29.99 payment adds Backup & Sync and encrypted backup, so your notes are never lost even if you switch phones.
Is it really a one-time purchase?
Yes. $29.99 once, through the App Store, and only if you want Backup & Sync. No subscription, no credit tokens.
What happens to my notes if I stop using Furu?
They're yours. Export everything as plain text at any time, free. Even if you never bought anything.
Do you see my notes?
No. Notes never touch our servers. There are no servers to touch. Your data lives on your device and, if you choose, in your own iCloud backup.
