Chat with every AI,
from one Nexus.

Nexus gathers your AI providers into one private dashboard — one shared memory across all of them, automatic failover when a provider hits its limit, and a trace that shows exactly who answered, and why.

Everything in one place

One dashboard houses the whole conversation — whichever AI is best for the next message, it continues right where the last one stopped.

One shared memory

Start a conversation with one AI and finish it with another. Nexus carries the full conversation across providers — when a chat moves, the next AI is handed the story so far, not a blank page.

Automatic failover

A provider hits its limit or goes quiet mid-chat? Nexus moves down the line and the reply still arrives — no dead ends, no copy-pasting your question into five tabs.

A trace on every reply

Each answer shows its working: which providers were tried, which one answered, how long each took, and the honest reason the others didn't. No silent swaps, ever.

Your keys, your vault

Connect the AIs you already have — paste your own provider keys, or sign in with ChatGPT, Claude and Gemini. Everything is stored encrypted; chat prefers your key, and nothing is ever shown to anyone else.

Private by design

Nexus runs on its owner's own server, for a small circle of invited people. No public sign-ups, no ads, no tracking — your chats stay yours.

Perfect set of tools

The composer wears many hats. Pick a mode and Nexus routes the job to a provider that can actually do it — and tells you plainly when one can't.

Text

Everyday chat, writing and questions, answered by the strongest lane available.

Code

Code-first models for building, debugging and reviewing — with the whole thread as context.

Web search

Answers grounded in the live web when a question needs today's facts, not last year's training.

Image

Describe it and get a picture back — generated images stay in your chat when you save it.

Voice

Talk instead of typing, and have long replies read back to you.

Video

Short clips from a prompt, through the providers that generate them.

Agentic

Multi-step jobs — research, gather, then write it up — run as one task.

Auto

Can't decide? Auto reads the job and picks the lane, the model and the mode for you.

An API of its own

Your other projects can call Nexus through its OpenAI-compatible /v1 endpoint — one service key, and the same shared memory, failover and lanes answer behind it. Point any OpenAI client at Nexus and it just works.

Get your service key
curl https://nexus.130-210-56-74.sslip.io/v1/chat/completions \
  -H "Authorization: Bearer <your service key>" \

       "messages": [{"role": "user",
                     "content": "Hello"}]}'

Frequently asked questions

The short, honest answers — the same ones the app itself gives.

Is Nexus free to use?

Yes. Nexus runs on free tiers and its owner's own server — there is no subscription and nothing to buy. When a provider's free limit is reached, failover simply moves your chat to another lane.

Who can join?

Nexus is invite-only: the owner invites a small circle of people, and there is no public sign-up — by design. If you were invited, use Sign in above.

Which AIs can I use?

The ones Nexus routes to — ChatGPT, Claude and Gemini, plus a bench of providers like Groq, NVIDIA, Mistral, Cohere, OpenRouter and Pollinations. Connect your own accounts and keys on the Connections page, and chat prefers them.

Where do my chats and keys live?

On the owner's server, encrypted. Saved keys are never displayed back after saving, and your chats belong to you — other members of the circle cannot see them.

Your AIs are already here.

One sign-in, and every provider you use is sitting on one desk.
