50+ models, one login

Every model in one workspace. Nothing on our servers.

Switch between Claude, GPT, Gemini, DeepSeek and 50+ more — mid-conversation. Compare them side by side, branch any thread, and keep full control of how each one runs. Every chat lives in your browser, never on ours.

See it in action

Run the models against each other

Send one prompt to several models at once and watch the answers stream in together. Pick the best response on the merits — not whichever model you happened to subscribe to.

Branch a conversation like code

Fork any thread at any point and explore directions in parallel. Navigate it all through a visual graph — version control for your thinking.

Why Nsonia Gateway

Everything in one place — yours or your team's

One login, one bill, one dashboard. Full access to Claude, GPT, Gemini and 50+ more, with clear visibility into what you're spending.

Every model, one login

Claude, GPT, Gemini, Llama, Mistral, DeepSeek — 50+ models. When one provider rate-limits or goes down, switch to another without leaving the chat.

Your chats stay on your device

Conversations are stored in your browser, never on our servers. We track usage for billing — never your prompts or your responses.

One bill, total visibility

No more five invoices from five vendors. A shared credit pool, per-person usage, and an admin view that actually shows where the money goes.

$25/seat. Every model.

One predictable line item covers every model. Each seat includes generous monthly credits, and extra credits carry over month to month — no waste, no surprises.

Experts

Build a specialized Expert, tuned exactly how you want.

An Expert is a reusable, specialized assistant you build yourself — grounded in the documents only you have, with the model and parameters you choose. Set it up once for the work you do, and come back to it again and again.

Specialized in your knowledge

Ground it in the PDFs, Word, Excel or notes specific to your work — it knows what you know.

Tuned your way

Pick the model and dial in the parameters that fit the task — and swap the model anytime you like.

Private by design

Your documents are parsed and indexed locally in the browser — never uploaded to a server.

Build once, reuse forever

Set it up for a domain or workflow, then return to it again and again.

Power features

Built for people who push the models

The controls you wish ChatGPT and Claude exposed.

Plan in Opus, build in Mistral

Architect with a heavyweight model, then switch to something fast and cheap to do the work — same thread, full context carried over.

Chat with your documents

Drop in PDFs, Word, Excel or text files and ask questions across them. Everything is parsed and searched right on your machine — your files never leave the browser.

Talk instead of type

Dictate your prompts hands-free with built-in voice input and a choice of speech-to-text models.

Tune the model from the chat

Temperature, Top-P, sampling — the dials most apps bury, right where you're working. Precise control when you want it, sensible defaults when you don't.

System prompt library

Build reusable system prompts and carry them to any model. Craft your assistant once, use it everywhere.

Goldfish mode

Need a clean answer with no baggage? Goldfish mode forgets everything that came before — one-off questions, zero context bleed.

Instant local search

Because your chats live on your machine, search is instant. Find anything across every conversation in milliseconds.

A proper workspace

Markdown, syntax highlighting, code blocks, and an interface built for long working sessions — not a toy chat box.

How it works

Up and running in minutes

No API keys to manage. No servers to run. No security review to pass.

Create your account

Pick a model and go

Choose from 50+ models or switch mid-conversation. Build system prompts, branch threads, run models side by side.

See where it goes

Track usage and spend by model — just for you, or across your whole team — from one dashboard.

The difference

What changes with Nsonia Gateway

How one platform compares to juggling separate model subscriptions.

Separate subscriptions

✕A separate ~$20/mo subscription for every model you want
✕Hit a rate limit, open another app, lose your context
✕Several vendor relationships, several invoices
✕No idea which models you're actually getting value from
✕Conversations scattered across four different apps
✕Paying for seats nobody remembers they have
