Record the raw thought
Your original audio and transcript form a durable archive entry that serves as ground truth for all subsequent processing.
“How do I know what I thinkuntil I see what I say”— E. M. Forster
A private Voice journal
Built for Apple Intelligence. Coming soon.

VOICE, HELD CLOSE
Speak freely. Let the sentence trail off. Capture the walk home, the breakthrough, the messy middle. Flow preserves the original moment, then helps you see the patterns inside it.
From voice to clarity
Your original audio and transcript form a durable archive entry that serves as ground truth for all subsequent processing.
On-device intelligence works in the background to make sense of your transcript, generating a title, topic labels, and a summarizing reflection.
Search across titles, labels, and raw transcripts to find exactly what you’re looking for. Off by default, Flow notes can also become accessible to the new AI-powered Siri.

Private by design
Flow is built for the parts of life you would never hand to an algorithm in the cloud. Recording, transcription, and intelligent reflection happen on your iPhone using Apple’s latest secure on-device technology.
There’s no Flow account. No advertising. No analytics. No app-owned server. No voice recording or journal transcript sent to a cloud AI provider.
Designed around the device in your hand
Flow is designed for Apple Intelligence-capable iPhones, including iPhone 15 Pro and newer. Those devices provide the intended on-device intelligence experience today.
As Apple improves its on-device intelligence and hardware through future iOS releases, Flow is designed to benefit where the platform makes those capabilities available.
