GPT, Claude, Gemini, Llama — plus image generation and natural-sounding voice — in a single fast, private chat app. Free to start. No credit card. No noise.

What you get

Everything you actually need from an AI app.

Every model. One subscription.

Talk to GPT-5, Claude, Gemini, Llama, and the best open-source models without juggling five accounts. Switch models mid-thread to see who answers best.

Built-in image & voice

Generate images, edit them, and turn any reply into natural-sounding speech — without leaving the conversation.

Personas & system prompts

Save reusable personas (writer, coder, analyst, support agent) with your own instructions, tools, and memory so you stop pasting the same brief every time.

Fast, distraction-free UI

A clean, keyboard-driven interface that opens instantly on web, mobile, and tablet. No ads. No upsells in the middle of your work.

Search the web

Toggle web search per message to pull in fresh sources, cited links, and live data — without losing your conversation context.

Your conversations are yours. We never train on your data and you can delete any thread permanently with one click.
