Your voice-first home for frontier AI.
No more getting cut off.
Tap once and speak your mind. Riffie never cuts you off. Pause to think, keep going, finish when you're ready. You decide when a thought is finished.
The reply plays itself, the second it lands.
Tap to send, and you're hands-free while you keep walking, driving, or just looking away from the screen. As the text streams in, so does the audio. Full controls when you want them: scrub, change speed, share.
A few personas, each built for a specific job.
A definitive call without the clutter of overthinking. No options matrix, no qualifiers. Just a confident recommendation you can put into action.
Pressure-test your ideas like you would with a sharp friend. Push past easy answers, weak assumptions, and vague thinking. Strengthen your thinking.
A jazz musician's "yes, and" instinct, applied to your thinking. The half-baked thought you almost dropped might be the unlock two steps later. Cross-domain connections nobody asked for. You leave with more possibilities than you walked in with.
Warm, unhurried, with a light Stoic sensibility. Reflection without the therapy framing. The benefits compound: clearer thinking, less rumination, better sleep.
Opinions, tangents, dissecting trivial things for twenty minutes if that's the mood. Two people riffing, no agenda. Sometimes the rambling itself gives you what you need.
Hand over a topic that's hard to grasp: gaslighting, quantum computing, or why do cats love knocking things over. An explanation that builds understanding, piece by piece, like the best teachers do.
No persona layered on top, just the model's defaults coming through.
Memory you shape, not memory that decides for you.
Group related conversations into a project. Riffie gathers what matters across them and keeps only what you approve, so the next conversation picks up where the last one left off.
One polished audio experience across all of them. A model that fits the work, a voice that fits the moment.
Same chat, same memory, different model. Try one for a week, switch when the work changes.
Warm and reflective. Catches nuance, sits with a thought, and pushes back when something feels off.
Sharp and methodical. Breaks complicated things down and keeps the through-line tidy.
Quick and direct. Lands the answer without preamble. Strong at knowledge work without slowing down to deliberate.
Each persona ships with a default voice tuned to its role. Override anytime.
More to choose from in the app.
Talk things through wherever you are, in an app built for spoken thinking.
Other voice modes water down the model and tuck the real response behind a mode switch. Riffie gives you the same depth you'd get typing, read aloud automatically, with the transcript right there.
A lot of our best thinking shows up on walks, drives, between calls. Riffie meets you there. Record a thought as long as you need, hear the response back, hands free for the wheel, the leash, the coffee.
Free to download on iPhone and iPad.
More in the app, in Settings, or by email.
A voice-first AI app for iPhone and iPad. Tap once and speak as long as you want. Riffie replies in audio, with the full transcript right there. Built for thinking out loud, hands free.
There's a free tier with a small weekly budget, enough to get a feel for it. Pro is a paid subscription that unlocks a generous weekly budget for daily use. New accounts get a free trial at the Pro budget so you can try it before deciding.
iPhone and iPad, running iOS 26 or newer. No Android, no web app. At least not yet.
Not to try it. After the free trial ends, signing in is required so your conversations sync across devices and your subscription follows you. Sign in with Apple, Google, or email.
Riffie does not sell your data, run ads, or track you across apps. Speech transcription happens on-device. Conversations sync to your private iCloud, not to a Riffie server. Full details on the privacy page.
Yes. Pick the model that fits the work in Settings, and the voice that fits the moment per persona. Same conversation, same memory, different model. Switch anytime.
Because that's what it's for: a place to riff out loud, with an AI that doesn't cut you off.
