Two heads, zero waiting
Your message routes to whichever head is free. Two assistants stream side by side, each with full context, generating independently — stop either one without losing the other. Stay in flow instead of watching a spinner.

Five things it does that most wrappers don't
Your prompt cache, made visible
Every wrapper hides the provider's prompt cache and lets a model switch silently blow it up at full price. Vantis Forge shows a live countdown, keeps it warm on a schedule you set, and warns you before a switch would cost you the whole context over again.
Documents that live outside the wall of text
Character sheets, codices, story bibles — pulled out of the transcript into their own editable, versioned documents. They only re-enter context when they're actually relevant, so a long-running world doesn't mean a bloated prompt.
Know your favorite model in minutes, not weeks
Stop trial-and-error across separate chats over days. Send one prompt to up to six models at once and read every answer side by side — you'll know which one fits before your coffee's cold. Save the prompt, and testing whatever model ships next is one click, not a redo from scratch.
See exactly what gets sent, every time
Full control over the system prompt and behavior notes that shape every reply — named, segmented, independently toggleable, and fully visible. No mystery prompt injected behind your back.
