# OneChater

> OneChater is an AI chat app that runs GPT, Claude and Gemini in one place with a persistent, per-user memory that travels across every model. It is bring-your-own-key (BYOK): users connect their own provider API keys and pay OpenAI, Anthropic and Google directly, with no markup from OneChater.

## Key facts

- One interface for multiple AI models: GPT (OpenAI), Claude (Anthropic), Gemini (Google), plus Groq, Amazon Bedrock, Azure OpenAI, Replicate and any OpenAI-compatible endpoint.
- Persistent memory: a private, editable, per-user memory profile that follows the user across every model. Encrypted, tied to the account only, never shared.
- Fusion: send one prompt to multiple models at once and merge their best parts into a single answer.
- Pricing: bring your own API keys and pay each provider directly with no markup. Free to start; upgrade for all models and persistent memory.
- Privacy: users keep full control — review, edit or delete stored memory at any time.
- Languages: English and Spanish.
