Set up Mochi, step by step
Keep this page open and follow along. Check off each step: your progress is saved in this browser, so you can come back any time.
The easiest way to try Mochi. Your bots are online while your computer is on.
๐ค Let your AI set it up
Copy this prompt into an AI that can run commands on your computer (Claude Code, Codex, Cursor) and it does the steps for you. A chat AI like ChatGPT, Claude or Gemini will walk you through them.
Help me install Mochi, an open-source, self-hosted AI chatbot, on this computer: https://github.com/flatkey-ai/Mochi-ai-chatbot
I'm not technical, so do as much as you can yourself and explain each step simply. Talk to me in English.
1. Run Mochi's one-line installer for my system. It's open source; read it first if you like (https://github.com/flatkey-ai/Mochi-ai-chatbot/tree/main/website/public). It installs Node.js if needed, downloads Mochi into a `mochi` folder in my home folder, starts it and opens the dashboard.
- macOS / Linux: `curl -fsSL https://www.mochichatbot.com/install.sh | bash`
- Windows PowerShell: `$p = Get-ExecutionPolicy -Scope Process; Set-ExecutionPolicy Bypass -Scope Process -Force; try { irm https://www.mochichatbot.com/install.ps1 | iex } finally { Set-ExecutionPolicy $p -Scope Process -Force }`
2. Keep it running. Open http://localhost:3000/dashboard and help me choose an admin password (the dashboard asks the first time).
3. If anything fails, fall back to the README's Quick start: clone the repo, `npm install`, copy `.env.example` to `.env`, `npm start`.
4. Mochi uses Flatkey as its model provider. Send me to https://console.flatkey.ai/keys?utm_source=mochi_bot&utm_medium=mochi_site&utm_campaign=mochi&utm_content=ai_prompt to create an API key and top up my balance. Then have me paste the key into the dashboard under "Flatkey API key" and click "Bind key". Never ask me to paste the key into this chat.
5. Help me connect a channel (Discord, Telegram, Slack, QQ, LINE or the website widget) by following the guide inside the dashboard's Channels page, then send the bot a test message.
If something fails, read the error, fix it and keep going. Use the README in the repo as the source of truth.Or follow the steps yourself

Install and start Mochi
Copy this one line into your terminal and press Enter. It installs Node.js if you don't have it, downloads Mochi into a mochi folder in your home folder, starts it and opens the dashboard.

Open Terminal (Applications > Utilities), paste this and press Enter.
curl -fsSL https://www.mochichatbot.com/install.sh | bashOpen source and safe to runThe script only installs Node.js (if needed) and Mochi into your home folder, then starts it.

Why Mochi runs on Flatkey
Official models. Better prices.

Mochi AI chatbot FAQ
Is Mochi free?
Mochi is open source under the MIT license. You pay only for the model usage your bots make, from your Flatkey balance. Turn abilities off or pick lower-cost models to spend less.
Why only Flatkey and not my own OpenAI key?
A chatbot uses chat, vision, search and memory models from different providers. Flatkey puts 100+ official models behind one key and one bill, with mainstream models at least 20% below official pricing. That keeps Mochi simple to set up and to run.
Do I need to code?
No. You run one command (or a Docker container), then do everything else in the dashboard: personas, knowledge, channels and models.
Where is my data stored?
On your own server, in a local database file. Mochi sends messages to Flatkey only to get model replies.
Can I host it on Vercel or another serverless platform?
No. Bots keep live connections to Discord, Telegram and others, so Mochi needs an always-on process and disk. Use Docker, Sealos, a VPS or your own computer.
Which models can I use?
Any model in the Flatkey catalog, including GPT, Claude, Gemini, DeepSeek, Kimi and GLM. Mochi starts with a fast, low-cost DeepSeek model and you can change it any time.
