Everything you need, nothing you don't

Bring your own key

Use your existing API keys from OpenAI, Anthropic, Google, Groq, or any OpenRouter-compatible provider. No middleman fees.

Hot-swap models

Switch between GPT-4o, Claude, Gemini, and more mid-conversation. Pick the best model for the task at hand.

Incognito mode

Toggle incognito to prevent conversations from being saved. Your data stays yours — always.

Smart rename

Retitle conversations instantly with AI, keep important threads pinned, and keep your history easy to scan without clutter.

Tunable responses

Adjust temperature, max tokens, and system prompts per conversation. Fine-grained control without leaving the UI.

Built-in quiz mode

Generate interactive quizzes from any topic. Study, test, and learn — powered by the model you choose.
