What is MangoTart?

A small computer that runs your own AI agent on hardware you own — and keeps your data on the box.

A private AI agent, on hardware you own

MangoTart is a small computer — a Raspberry Pi 5 in an aluminium case — that runs an AI agent called Hermes. You talk to it from the chat apps you already use (Telegram, Discord, WeChat, and more), and it can read email, draft texts, browse the web, remember things, and run tasks on a schedule.

The whole point: it's yours. The agent's memory, your conversations, and every key it uses live on the box on your desk — not on our servers.

Bring your own AI provider

We don't sell tokens or run a model proxy. The box's job is to get your own AI provider working. During setup you pick one:

  • A ChatGPT subscription (recommended) — use your existing ChatGPT Plus / Pro / Go account. No API key, no extra cost.
  • Any provider Hermes supports — your own API key (OpenAI, Anthropic, DeepSeek, Gemini, and more), an OAuth login, or a custom OpenAI-compatible endpoint.

Billing always stays on your own provider account — we never see it and never charge you for usage.

Why this matters

Because the model is yours and the data is on the box, there's no middleman between you and your agent. We bind the box to your MangoTart account for warranty and support only — never for billing.

What you can do with it

  • Chat from Telegram, Discord, Slack, WeChat, Lark, and a dozen other apps.
  • Email — let the agent read and draft from your own mailboxes. See the Email tool.
  • Texts — have the agent draft SMS for you to approve and send. See the SMS tool.
  • Browse — sign the box's browser into your accounts so the agent can act on the web.
  • Remember — a memory file the agent keeps about you and the people and projects you mention.
  • Schedule — recurring tasks, like a morning briefing delivered to your chat app.

How setup works

The box has no screen, so you set everything up from your phone or computer.

1

Plug in

Connect power and an Ethernet cable. The box comes online by itself — no configuration needed.

2

Open it

Visit the address printed on the box's sticker (http://mango-xxx.local). Can't reach it? Open the find page and enter the short code on the box to get a clickable link.

Onboard

A guided wizard binds your account, picks your model provider, sets your timezone, and connects your first chat app. That's it.

Once setup is done, open Telegram (or whichever app you connected) and start chatting with your agent.
