Riff
Read full descriptionHide full description
Your best thinking happens out loud — on a walk, in the car, pacing the kitchen. Riff is where it goes. Talk. Riff turns what you said into a clean transcript, then a short recap with the action items pulled out, right in front of you. The rambling was the thinking. The recap is what you keep. And if the recap isn't quite what you meant, say so — every riff comes with its own agent. "Focus it on the budget." "Add an action about the dentist." "Shorter." It reshapes the recap while you watch, tells you exactly what it changed, and keeps versions so one tap steps you back. Ask it questions, too; it answers only from what you actually said. And it never rewrites your transcript — your words stay yours. Here's the part that matters: all of this happens on your iPhone. Not on "secure servers" — on the phone in your hand. Flip on airplane mode and Riff works exactly the same: recording, transcript, recap, agent. No account, no sign-in, and a privacy label that reads Data Not Collected, because nothing is. That's also why there's no subscription. No cloud means no cloud bills, so riff+ costs $19.99, once. And because the AI is Apple's on-device intelligence, Riff genuinely improves as iPhones do — buy it once, and it gets smarter every year. A thought can arrive anywhere, so Riff can start from anywhere — the Action Button, your Lock Screen, the Dynamic Island — before it gets away. Free, forever: recording, live transcription, editing, your full history with search, and export. Plus 5 recaps and 10 agent requests to try everything. riff+ simply makes recaps and the agent unlimited — everything else was already yours. Riff is for your own thinking — ideas, plans, the stuff you'd otherwise lose. It's a small, fast, private AI, and honest about it: treat a recap as a sharp first draft, not a legal document. Requires Apple Intelligence (iPhone 15 Pro or later, iOS 26+).
