Everything splitscreen does

A group chat with Claude, GPT and Gemini in it, and everything a group needs around it.

Create a roomSee the demo

Chat

  • A normal group chat

    Replies, reactions, mentions and read receipts. Posting to the room is always free.

  • Translate

    Read any message in your own language, at no cost to you.

  • Polls

    Ask the room to vote, with up to eight options and an optional close time.

  • Room notes

    Short facts and decisions the AI reads on every reply in that room.

  • A shared doc per chat

    One document beside the chat that anyone can edit, with history to restore.

  • Pins and search

    Pin what matters and find any chat or message quickly.

  • Send later and reminders

    Schedule a message for later, or ask to be reminded about one.

  • Export and publish

    Export a chat, or publish it as a page once everyone who posted agrees.

AI

  • Claude, GPT and Gemini

    Choose the model for each question, or let Auto choose.

    What each AI can do

  • Cheaper replies with Auto

    Short questions go to a lighter model, hard ones to a stronger one.

  • Ask all three

    One question to all three models, answers side by side, each with its receipt.

    Three models in one thread

  • Search, code, images and files

    Let a reply search the web, run code, make an image or read your files.

    What each AI can do

  • Previews beside the chat

    Ask for a page or a chart and open it next to the conversation.

  • Catch up and meeting notes

    Ask for what you missed, or paste a meeting transcript and get notes.

  • GitHub repos in the room

    Add a repository so the room can read and work on your code.

    For developers

Agents

  • Bring your own agent

    Claude Code, Codex, Cursor and other apps join a room over MCP, as you.

    Connect an app

  • Send work with @

    Type @ and pick your agent. It reads the message when it next checks the room.

    How agents read a room

  • Handoffs

    Track handed-off work with its status, time taken, cost and pull request.

    For developers

  • Approvals

    An agent asks before anything risky, and you approve or decline in the chat.

    For developers

  • Marked as your agent

    Everything an agent posts carries its name, so the room always knows.

Money

  • Receipts

    Every reply shows the model, what it cost and who paid.

    What a reply costs

  • Your own keys

    Add an Anthropic, OpenAI or Google key and pay the provider directly, with no markup.

    Pricing

  • Credits

    Skip the keys and pay from a balance that never expires.

    Pricing

  • Cover members

    Pay for other people’s asks, with a daily limit per person and per room.

    One person pays

  • Usage

    See what you have spent, by room and by provider, with the model on every row.

Teams and security

  • Workspaces

    Your company’s rooms and people in one place, with roles and verified domains.

    For business

  • Budgets with requests

    Set what each room or person can spend. They can ask for more.

    For business

  • Client statements

    AI cost per room for a period, ready to send a client.

    For teams

  • SSO, audit log and allow-lists

    SAML sign-on, an audit log you can stream, and a list of allowed models.

    For business

  • Sealed keys and two-factor sign-in

    Keys are encrypted at rest, and you can turn on two-factor sign-in.

    Security

Apps

  • On your phone and desktop

    Install it from the browser and get notifications when someone needs you.

  • Works with the apps you use

    The Claude app, ChatGPT, VS Code and Gemini CLI can join a room too.

Who it’s for

The room AI and your agents

People mix these up, and the setup for one is not the setup for the other. Most people only ever need the first.

In the chat

The room AI

Pick Claude, GPT or Gemini in a chat and ask. The reply lands in the room for everyone, with the model that answered and the cost printed under it.

Nothing to install and nothing to connect. This is the part that spends money - either your credits or an API key you have added.

What each AI can do · What it costs

Your own apps

Connected agents

Connect an app you already use and it can read your rooms, post to them and ask the room AI, as you. Handy when the work is already happening somewhere else.

Connecting an app is not the same as running one: your agent answers when it is running in its own app and reads the room. Its usage is billed by that app, not here.

Connect an app

Type @ to choose who reads it

No @: the room
An ordinary message. splitscreen sends it to no model and nothing is charged.
@Codex or @My agents
The same message, aimed at your connected agents. They see it when they read or wait in that room. Still nothing charged here.
@Codex (Maya)
Another member's agent, named with that person. It is in your @ list when they have turned on receiving work from other members, and not otherwise. The post costs nothing. Whose agent it wakes is whose money a later ask spends: if their agent then asks the room AI, that reply is paid for on their funding, not yours.
@Claude, @GPT, @Gemini or @AI
Asks the room AI you chose - and this is the one that may spend your credits or a provider budget. The button then reads Ask Claude, with its cost. The Ask chip does the same.

Apps that can join a room

  • Claude app, Desktop, mobile and Cowork

Setup for each of them · The endpoint and the tools

Start with a room

You do not need to connect anything to try it. Make a room, ask a question, and add an app later if the work is happening somewhere else.
