Your AI team, always on.

Mates are AI teammates with a name, a job and a memory. They work across your apps, hand tasks to each other and only ping you when a decision is needed.

A mate is a teammate, not a chatbot.

Each mate has one clear job and gets better at it. You set it up in plain words, like briefing a new colleague.

Inbox triage

Checks your inbox every weekday at 7:30 AM

How it should work

“Every morning, read my inbox, tell me what needs me and draft the replies. Never send anything without my OK.”

Plain words. No prompt engineering.

Remembers

Sara at Lumen Records prefers calls on Tuesdays. Invoices go in the Finance label.

You can read and edit everything a mate remembers.

Uses

Gmail, Google Calendar and its own browser

Connectors for Slack, Notion, GitHub and dozens more apps, plus any MCP server.

Asks first

Before sending an email or deleting anything

Anything that sends, publishes, buys or deletes waits for your OK.

Model

Your ChatGPT plan

Each mate can use a different model.

Questions

Anything else? Write to hello@nextmates.app.

What exactly is a mate?

An AI teammate with a name, a job and a memory. You chat with it like with a colleague; it uses your apps and its own browser to get things done, and checks with you before anything important.

Does my data leave my computer?

With the desktop app, your mates, chats, memory and files are stored on your computer. Conversations go only to the AI provider you pick to run your mates, and to the apps you connect. Nothing is stored on our servers unless you turn on NextMates Cloud.

Where does NextMates Cloud run?

On servers in the European Union. Each account runs in its own isolated space, and keys and tokens are stored encrypted.

Which AI models can my mates use?

Your ChatGPT plan (sign in with ChatGPT), GitHub Copilot, API keys from Anthropic, OpenAI, OpenRouter, Google Gemini, xAI, Groq, Mistral and DeepSeek, or local models through Ollama and LM Studio. Each mate can use a different model.

How much will it cost?

The desktop app is free. NextMates Cloud will come in two plans: Cloud, with your own API keys, and Cloud Plus, with AI credits included every month, so you don’t need an API key. Prices will be announced at launch; the private beta is free.

Will my mates do things without asking?

Only what you allow. Reading and research happen on their own; sending, publishing, buying and deleting wait for your OK, unless you tell a mate it can go ahead.

Does it work on Windows, Linux or my phone?

Yes: the desktop app runs on Mac, Windows and Linux. NextMates Cloud adds a phone app for iPhone and Android, so you can talk to your mates from anywhere.

How does the private beta work?

We invite people in small groups. Request access with the form above and we’ll email you an invite. During the beta things change quickly, and your feedback shapes what we build.
