One provider, or all of them
ChatGPT is an excellent product — but it gives you one company's models. Nsonia Gateway is a single workspace for every major model: the GPT family you already know, plus Claude, Gemini, Llama, Mistral, DeepSeek and more. Pick the best model for each task instead of the only one you're subscribed to — and switch between them without leaving the conversation.
When ChatGPT is the better pick
ChatGPT leads in a few areas we don't try to match: its large GPT Store of pre-built assistants, code execution and advanced data analysis, and its autonomous agent that completes multi-step tasks for you. If those are central to your work, stick with ChatGPT. Nsonia Gateway is built for the broader case — every major model in one place, a single bill across your team, parameter control, custom Experts whose knowledge stays on your device, and conversations that never leave your browser.
We think Nsonia Gateway is the better fit for most teams — but here's the honest case for the alternative, so you can decide for yourself.
Common questions
Can I still use GPT models on Nsonia Gateway?
Yes. The latest GPT models are included alongside Claude, Gemini, DeepSeek and 50+ others — all under one subscription, with no separate API keys to manage.
Does it have custom GPTs?
Yes — we call them Experts: a reusable assistant with its own system prompt, your own documents, and the model of your choice. Unlike ChatGPT's custom GPTs (GPT-only, with files uploaded to OpenAI), an Expert can be built on any model, and its knowledge is indexed locally in your browser.
How is the price different from ChatGPT Business?
It's in the same ballpark per seat — but instead of one provider's models you get every major model, plus side-by-side comparison, conversation branching, parameter control, and browser-only conversation storage.
Do you store my conversations the way ChatGPT does?
No. Your prompts and responses live entirely in your browser's local storage, and we only track aggregate credit usage for billing. ChatGPT stores conversations on its servers and, on consumer plans, trains on them by default unless you opt out.
Can my whole team use it?
Yes. Everyone shares one credit pool, with per-person and per-model usage visible from a single admin dashboard — no per-user setup.
Every model — including the one you already use
$25/seat. 50+ models. One login. Your conversations stay on your device.
