Catalyst puts today's best AI models in one place — and lets you switch between them with a tap. Chat with models from Anthropic, OpenAI, Google, and more in a single conversation, and bring your own API keys so you're never locked in. WHAT YOU CAN DO • Chat with multiple AI models — pick the right one for each question, or compare answers side by side • Generate images from a prompt, and create or animate short video clips • Run Python in a secure sandbox for calculations, data analysis, and charts • Search the web for current information, with sources • Attach photos and files and ask about them • Give the assistant a memory that carries useful context across conversations BRING YOUR OWN MODELS Catalyst is model-agnostic. Connect your own provider keys — Anthropic, OpenAI, Google, or any OpenAI-compatible endpoint — and use the models you choose at the provider's own rates. A better, cheaper model ships every few weeks; point Catalyst at whatever's best today. YOUR DATA, YOUR CONTROL Your conversations sync securely so your history follows you across devices. Export everything you've created at any time, and delete individual chats — or your whole account — from inside the app. Catalyst on iPhone and iPad is the companion to the full workspace at catalyst.voov.ai, where you can also build workflows, mini apps, and connect data sources.
