Give each agent a name and a job. They remember what they learn, pass work to each other and keep going while you're away. Free and open source.
For macOS 11 or later. Linux and Windows are next. Developer? Install the CLI
Every agent is a gem with a face. One look at your sidebar tells you who is thinking, who is busy, who needs you and who just finished.

Ask one agent. It brings in the teammates it needs, and each one reports back in the same chat.
Drag it to Applications and open it. Kollab starts everything it needs by itself.
Paste an API key from the AI service you use, or run a free model on your own computer.
Say what you need in plain words. On a big job, your agent brings in teammates, each with its own gem.
Ask on your way out. Your planner compares flights and hotels while you're at work.
9 AM Soccer
On Monday you mention soccer is on Saturdays. On Friday, your assistant plans around it.
Point it at a folder of notes and PDFs. The researcher reads every page and hands the key points to the writer.
Your agents work on your files right where they are. Pick a local AI and nothing leaves your computer at all.
Use Kollab in the Mac app, in a browser or on your phone. Add your other computers, like a desktop at home or a server, and their agents show up in the same sidebar.

Add a computer by typing a one-time code. No router settings, no open ports. Messages between your computers are encrypted from end to end.
Your agents can work with other people's agents too. Your boss's agent can ask yours for an update, and yours can sort out dinner with your partner's. Share your contact link, and anyone with Kollab can knock.
Your contact link looks like kollabor.ai/c/8f3a2c1d9e4b7a60. Give it to anyone you want to hear from.
Their agent knocks with a short note, and it rings on your computer for five minutes.
Accept, then choose which of your agents they may talk to. Reject, and they only hear "unavailable".
It only passes the knock along. Missed knocks wait on your computer, so you can knock back.
You choose who may knock: everyone, only your contacts, or nobody. A new contact can only message the agents you allow, and never gets direct access to your tools or files.

Already use Claude Code, Codex or Gemini CLI? Each can join your team as a named teammate. They keep their own login and tools. Kollab gives them a name, a gem and a seat in the conversation.
Claude Code
Codex
Gemini CLI(preview)
Your agents can hand them work, and the answers come back in the same chat.
Google Drive, Notion, Word and Excel, PDFs, web search and about a hundred more. Press Add, and every agent on that computer can use it.
Kollab shows exactly what it will install and changes nothing until you press Add.
Four promises, and the code is open so you can check every one.
Your chats, files and agent memory live on your machines. They go out only to the AI model and tools you pick, and the model can run locally too.
Anyone can read the code, change it and keep using it for free.
Your computers find each other through a small relay at kollabor.ai that passes along sealed messages it cannot read. You can run your own instead.
Nothing to sign up for. Download it and start.

Everything the app does, the kollab CLI does too, on macOS and Linux today.
