How to Set Up a Personal AI Assistant on Telegram (Free)

Imagine having an AI assistant in your pocket. You message it on Telegram, it responds instantly, and it handles tasks for you — research, writing, scheduling, coding. All from your phone.

This is not a product you need to buy. You can build it yourself in about 20 minutes using free tools. Here is exactly how.

What you need before starting:

A Telegram account (free, on mobile or desktop)
A computer to run the setup (can be a laptop, not a server)
10-15 minutes of focused time

Why Telegram?

Telegram is the best interface for a personal AI assistant because:

You already use it — no new app to learn
Works on mobile and desktop, synced automatically
Supports bots with full API access
Fast, reliable, free

Your AI assistant becomes just another chat contact. You message it the same way you message anyone else.

The Approach

We will use OpenClaw — an open-source AI agent framework that runs locally on your machine. It connects to Telegram and gives you a powerful assistant powered by free models.

Alternative approaches exist (like BotFather + custom code), but OpenClaw is faster to set up and comes with tool support built-in.

Step-by-Step Setup

Install OpenClaw

Open your terminal and run:

curl -sSL https://get.openclaw.com | sh

Follow the prompts. Accept defaults. The install takes 1-2 minutes.

Get a Free API Key

Go to openrouter.ai and sign up (free, no credit card). Create an API key at openrouter.ai/keys.

Copy the key. You will paste it in the next step.

Configure Your Environment

Create or edit the environment file:

# ~/.openclaw/.env
OPENROUTER_API_KEY=sk-or-your-key-here
                

Replace "sk-or-your-key-here" with your actual API key.

Create Your Telegram Bot

Open Telegram and search for @BotFather. Start the chat and follow these commands:

Type /newbot
Give it a name (e.g., "My AI Assistant")
Give it a username ending in "bot" (e.g., myai_assistant_bot)
Copy the HTTP API token BotFather gives you

Add the token to your environment:

# ~/.openclaw/.env (add this line) TELEGRAM_BOT_TOKEN=your-token-here
