Why Another AI Chat Platform?

Multimodel Chat is a bring-your-own-key (BYOK) AI chat workspace that brings GPT, Claude, Gemini, Grok, and 500+ models into one interface. Instead of stacking multiple $20/month subscriptions, you pay a $2 monthly platform fee and use your own API keys to pay AI providers directly at their actual rates.

You're paying $20 for ChatGPT Plus, $20 for Claude Pro, and maybe another $20 for Google AI Pro. That's $60+ a month before you've used the APIs directly.

See the full cost breakdown.

Multimodel Chat works differently: bring your own API keys, use any model, and pay providers their actual rates, not marked-up prices.

What is BYOK? Bring Your Own Key means you use your own API keys from AI providers like OpenAI, Anthropic, and xAI instead of paying a platform subscription. You pay the provider's API rates directly while the platform charges a small infrastructure fee.

How BYOK Pricing Works

Instead of charging $20/month per AI provider like traditional platforms, Multimodel Chat keeps it simple:

$2/month platform fee — covers infrastructure, encryption, and the multi-model workspace
You pay AI providers directly at their API rates with no markup
Zero lock-in — stop anytime, your keys stay yours

Can I switch between models mid-conversation?

Yes. Multimodel Chat lets you switch between GPT-5.6 Sol, Claude Opus 5, Grok 4.6, Gemini, and more without leaving the conversation.

Is my data private and encrypted?

Yes. Provider API keys are encrypted with AES-256 in your browser's vault and sent per request over TLS. Conversations are stored in your browser and you can delete them at any time. For more on AI chat security, see our guide on platform safety.

What if I already have API keys?

Perfect. Enter them during setup — Multimodel Chat encrypts them with AES-256 and never shares them. You can revoke them anytime from your provider's dashboard.

How is Multimodel Chat different from ChatGPT Plus?

ChatGPT Plus charges $20/month regardless of usage. Multimodel Chat charges $2/month for infrastructure, and you pay the provider directly at API rates — often $3-15/month depending on usage. The BYOK model means you're never paying for someone else's API credits.
