Riffn is your hands-free voice-link to any model, any agent, anywhere. Local or cloud. Your best ideas don't happen in front of a screen. Vibecode while you walk the dog. Drive any agent, or chat with any model, by voice without touching your phone or your keyboard. Write code, build a business, prepare for work presentations, or develop ideas from anywhere. Riffn is voice-first, hands-free and eyes off: Enjoy a conversation riffing on your favorite topics while you drive, walk, run, do weighs, do chores, or even lie down with your eyes closed. Switch seamlessly between coding agents by voice. Talk to your own cloud agent on your mac-mini then switch by voice command instantly to requesting edits from your favourite repo agent on your laptop then switch again to developing ideas on a separate project with one of 17 Riffn models or use your own API keys and speak with any model you have set up. Never touching your phone once. Voice and audio prompts and Riffn's Assistant Mode ensure you know which agent you're connected to and what your options are. You're in control. Hands-free, eyes off. Full control, No Interruptions: Talk fast, or pause often. Think it through mid-sentence. You decide when the AI responds. Super low-cost: Turn-based conversations at a fraction of the cost. Chat with your agents: Speak with your own custom agents or local models from anywhere instantly. Terms of use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

  • This app hasn’t received enough ratings or reviews to display an overview.

Faster, steadier conversations • Riffn now recovers from network dropouts mid-conversation instead of going quiet. • Connections warm up as you start speaking, cutting the pause before the first reply. • A new voice is the default for standard speech, with clearer, more natural delivery. • If speech is interrupted, the on-device voice now picks up where it left off rather than starting the sentence again. Fixes • Riffn's own voices now work when you're using your own API keys for reasoning. • Managing your API keys is clearer: one screen per provider, with an option to reveal a key so you can check what you pasted. • "Surprise Me" no longer re-introduces the same project at the start of every reply. • Turn timing under the text box can now be split into provider, network and playback, so you can see where a slow reply actually came from.
