Face/Off mode is a game changer

Chaizon

Okay so the face/off mode is pretty great. It gives me 3 responses back from Claude and/or OpenAI and then judges the best. This has been a life saver for really nitty gritty detailed document work for me.

FACE/OFF MODE IS HERE

Generate 3 AI responses with different creativity levels (conservative, balanced, creative). Then an AI judge evaluates all 3, picks the winner, and tells you why it's superior.

Stop doing manual trial-and-error. Get the best response on the first try.

Perfect for critical tasks: business emails, complex code, research. When quality matters more than cost, Face/Off Mode delivers.

Why consumer apps will never build this: Subscription models want you messaging more, not getting perfect answers immediately. With pay-per-use, our incentives align with yours.

Uses ~5x the tokens, but when you need the absolute best response, it's worth it.

DOCUMENT WORKSPACE
Finally. Stop squinting at chat bubbles. Full-screen document interface for actual work. Edit AI responses inline. Read long outputs without wanting to throw your phone.

ICLOUD SYNC
Your conversations, API keys, and settings now sync across iPhone, iPad, and Mac via your personal iCloud. Not our servers—yours. Start a conversation on your phone, finish it on your Mac.

BETTER CONVERSATION EDITING
Edit any message—yours or the AI's—to refine context. Delete off-topic tangents. Fix the AI's mistakes mid-conversation. Better context = better responses.

And of course a bunch of bug fixes and little-bitty features.
