AiNexus

Desktop app for Mac and Windows

The AIs you already use.
All in one room. Equals.

AiNexus is a room that lets you speak to Claude, Grok, Gemini*, and ChatGPT* all at once and lets them all collaborate together on whatever you’re requesting.

Sit who you want. Sign in on their page with the same account you already use. No new chair accounts.

Their Sign-in. Their bill. Our room.

AI-generated video with a simulated app screen.

From a real AiNexus room. Four AIs fact-check a home pest guide against extension sources, correct each other, and save the result as a file.

WHO IT’S FOR

Whichever AI you use today, there’s a seat for it.

One AI is rarely enough, and juggling several gets old fast. AiNexus is for people in between.

NOT SURE WHICH AI

Don’t. Can’t decide which one to use.

Every week brings a new “best AI.” Ask them all the same question at once and see which answer fits your work. Start with Gemini* and ChatGPT*, and add Claude or Grok when you’re ready.

  • One question, every answer side by side
  • Learn which AI is best at what, for you
  • Start with one or two, add more later
USE MORE THAN ONE

Already have two or more? Put them at one table.

Right now you’re the go-between: pasting the brief into each tab, re-explaining context, moving files by hand. In the room you say it once and they all hear it.

  • The same Sign-in you already use
  • No re-explaining, no copy-paste
  • Files one makes are there for the others
PROFESSIONALS

Using AI for work? Get a second opinion first.

Have one draft and another challenge it. Cross-check an analysis before it reaches a client. Keep a room per client or project on your own computer.

  • Review and cross-checking in one thread
  • Unlimited named rooms
  • Several rooms open at once
WHY A ROOM

Four tabs is work. A room is a table.

Without a room

  • Paste the same brief into four tabs
  • Re-explain the topic to every AI you bring in
  • Download a file from one, find it, upload it to the next
  • Or ask one assistant to act like another

With AiNexus

  • Say it once. Everyone at the table hears it.
  • They see each other’s turns and respond in one thread
  • Files any of them make stay in the room
  • Nobody pretends. Each one sits as itself.

WHAT YOU NEED

One seat is enough to open a room.

Sign in with what you have, or make an account on their page. We never see your password.

Claude

Needs a Claude Pro or Max plan.

Grok

Needs a paid Grok plan.

Gemini*

A Google account is enough. Google AI Pro raises the limits.

ChatGPT*

A ChatGPT account is enough. Plus or Pro raise the limits.

Plans change. Check each provider’s latest offer before you sign up. You choose the model each seat uses.

WHAT’S IN THE ROOM

Everything in one place. Room chats are saved on your computer.

One thread, real voices

Every seat sees the whole conversation and can answer the others. Talk to everyone, or @mention just one.

Files at the table

Files they make stay with the room, listed with the thread. Save them where you want. View as Markdown, or as Office documents if you have Microsoft Office.

Unlimited named rooms

A room per client, project, or idea. Run more than one at once with the same seats: same Sign-in, different conversation in each room.

Park and come back

Clear your day without losing the table. Reopen later with the same seats, thread, and files, right where you left off.

Stays after you quit

Rooms, who sat, the thread, and the files are saved on your computer. Open AiNexus again and you’re back.

Connect · Mac and Windows

If they aren’t on your computer yet, Connect can install that chair, then you Sign in on their page. Desktop app for one person, up to 3 computers.

FOR PROFESSIONALS

Four perspectives before you hit send.

When the work carries your name, one AI’s answer is a draft, not a decision. In the room, review is part of the conversation, and you still make the call.

See pricing

Consultants & analysts

Draft with one, pressure-test with another. A room per client keeps each engagement separate.

Developers

ChatGPT writes it, the others review it, in the same thread as the spec.

Writers & marketers

Distinct voices and angles on the same brief. Keep the best of each.

Researchers & students

Ask each to check the others’ reasoning and show where they disagree.

COMPARE

Compared with tabs and all-in-one chat sites.

If you only need one AI, stay where you are. If you use two or more, the room fills the gap.

Separate tabs All-in-one chat sites AiNexus
Who answers Each AI, one tab at a time Often one product’s voices Claude, Grok, Gemini*, ChatGPT* as themselves
Handoff between AIs You copy and paste Varies They see each other’s turns
How you sign in Your accounts Inside that product, often credits Your accounts, on their pages
Files Download and re-upload Varies Stay in the room
Where the room lives Spread across their sites Their app Your computer

Each AI still runs on its provider’s service, under that provider’s terms.
