Vantis Forge

Own your AI. Forge your worlds.

your next message is always ready

A workspace built around your own API key — parallel replies, protected caching, living artifacts, and a model tester, all in one place.

Assistant 1

Assistant 2

Five things it does that most wrappers don't

FlowChat

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.

Cache

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.

Artifacts

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.

Arena

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.

Prompts

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.
