Use every major AI model in one workspace.
One workspace that knows how to talk to GPT, Claude, Gemini, and Grok — plus 100+ more through OpenRouter. Pick the best model for the moment, and pay only the provider.
Any model. One workspace.
GPT-5.6 Sol, Claude Fable 5, Grok 4.6, Gemini 3.1 Pro — and 100+ via OpenRouter. You pay each provider at cost. We add nothing on top.
Web search included
200 app-funded searches a month on Pro — 10 during the trial. Lifetime uses your own LinkUp or Exa key.
Drop any file in
PDFs, images, code, documents. We extract the text so the model can actually read it.
Branch any reply
Don't like the answer? Fork the conversation and try a different model, without losing the thread.
Keys encrypted at rest
Choose hosted encrypted storage or local browser encryption. Hosted keys are decrypted for requests; local keys are used ephemerally.
Bring custom endpoints
OpenAI-compatible? Ollama? Azure? Anything speaking that protocol plugs right in.
No training on you
We don't train on your conversations, don't resell your data, don't even look at it.
Every major AI model.
One workspace.
Connect your API keys from any provider and access all models from a single interface. Switch mid-conversation without losing context.

Built for people who
use AI seriously.
Model switching mid-conversation
Start with GPT for a first draft, switch to Claude Opus for review, then use Grok for real-time research — all without losing conversation context. One click to switch, zero friction.
AES-256 encrypted API keys
Choose hosted encrypted storage or local browser encryption. Hosted keys are decrypted server-side for provider requests; local keys are sent over TLS for one request and used in memory.
Zero markup on AI usage
You pay OpenAI, Anthropic, xAI, Google, LinkUp, and Exa directly at their published rates. Multimodel Chat never marks up usage. Pro is $4/month; Lifetime Access is $39 one time.
Web search integration
Search the web directly from your chat using App Search, your own LinkUp key, or your own Exa key. Get real-time information and cite sources. Pro includes 200 app-funded searches; Lifetime uses your own search key.
File uploads and document analysis
Upload images, PDFs, documents, and code files. Models with vision capabilities can analyze images. Text is extracted from documents for AI processing.
Conversation history and branching
Your conversations are saved and searchable. Branch from any message to explore different directions. Pick up where you left off across devices.
