What You Get
Debate Like Never Before
Six iconic personas. Live spoken audio. On-device AI. Everything you need to argue any idea from every angle.
Live Spoken Debates
Watch arguments unfold word by word with real-time voice playback and synchronized text reveal. Every debate is heard, not just read.
Challenge AI Directly
Enter the ring yourself. Type or speak your argument and have the AI persona respond to you directly — point by point, by name.
Neutral Moderator
An AI moderator wraps every debate with a structured analysis — strengths, weaknesses, winner verdict, and open questions left to explore.
iPhone & iPad Native
Built entirely in SwiftUI with layouts optimized for every screen size. Fluid animations, crisp typography, and a design that feels at home on Apple devices.
100% On-Device Privacy
Powered by Apple Intelligence FoundationModels. Your debates never leave your device. No account. No cloud processing. No data harvesting.
Debate History
Every debate is saved with a full transcript. Browse past arguments, revisit key moments, and re-run any saved debate with one tap.
Topic Suggestions
Stuck on what to debate? Get AI-generated topic ideas across politics, technology, ethics, society, and more — generated on-device, refreshed on demand.
Deep Customization
Choose voices per speaker, set round count, adjust AI temperature, pick any persona matchup, and toggle spoken vs. text-only playback.
Conversation Depth
Turn on Long Conversations for extended, argument-rich turns perfect for deep-dive discourse. Turn it off for snappier, punchier exchanges — same topic, completely different feel.
Re-Debate Instantly
Found a topic worth exploring again? Replay any saved debate with the same configuration — same personas, same topic, fresh arguments.
See It In Action
Beautiful on Every Screen
Fluid animations and crisp layouts designed for iPhone and iPad — every screen polished to feel at home on Apple devices.

Apple Intelligence
Runs Entirely On Your Device
Debate Companion uses the FoundationModels framework introduced in iOS 26 to give third-party apps direct access to the on-device Apple Intelligence model — zero latency to the cloud, zero data leaving your phone.
On-Device LLM
Apple Intelligence FoundationModels power every debate response. No API key, no server costs, no round-trip latency.
Private by Design
Your topics, arguments, and debate history never leave your device. Full privacy is the default, not an option.
Real-Time Streaming
Responses stream token by token directly from the on-device model, delivering the same fluid experience as cloud AI.
Works Offline
No Wi-Fi required. Debate on a plane, in a park, or anywhere — Apple Intelligence works wherever your device does.
