A Telegram bot built with Python uses the python-telegram-bot library to handle incoming messages and an AI SDK to generate intelligent responses. The core loop is: receive message, send to AI API with conversation history, return response to Telegram. At aidowith.me, the Telegram Bot route covers 14 steps over about 3 hours. You set up the bot handler, connect to OpenAI or Anthropic, add per-user conversation memory using a dictionary that stores message history by chat ID, and deploy to Railway. By the end, the bot is live and handling real conversations. The route uses Python throughout and includes working code for each step. Conversation memory is the part most guides skip and where most bots fall short. The route covers the dictionary pattern that keeps context without a database, which is enough for most use cases.

The Problem and the Fix
Without a route
- Python Telegram bot tutorials often stop at basic commands. You want a bot that handles open-ended AI conversations.
- Managing conversation history in Python without a database is unclear from most guides.
- Deploying a Python bot to the cloud involves environment variables and webhook setup that's easy to get wrong.
With aidowith.me
- Use the python-telegram-bot async handler pattern that works reliably with AI API calls.
- Store conversation history in a per-user dictionary that keeps the full context without a database.
- Deploy to Railway with environment variables so your API keys stay out of the code.

How It Works
Set up the Python environment and bot
Install python-telegram-bot, create the bot via BotFather, and write the basic message handler.
Integrate the AI API with conversation memory
Connect the AI SDK, store message history per chat ID, and pass context with each new message.
Deploy to Railway
Push to Railway, set environment variables for API keys, configure the webhook, and test live.

"The hardest part was conversation memory. The route showed me the dictionary pattern and it worked. The bot's been running for 3 months without issues."- Backend developer, startup
Questions
Install python-telegram-bot and openai packages. Create a bot via BotFather, get your OpenAI API key, and write a message handler that sends the user's message to the OpenAI API and returns the response to Telegram. The aidowith.me Telegram Bot route covers this in 14 steps with working Python code at each step, including the conversation memory pattern that most guides skip.
python-telegram-bot is the most widely used and well-documented option. It handles webhooks, polling, message types, and async handlers out of the box. Aiogram is a good alternative with a more modern async-first design. The aidowith.me route uses python-telegram-bot v20+ with async handlers, which is the current recommended setup for production bots.
Store message history as a list per chat ID in a Python dictionary. With each new message, retrieve the history for that chat ID, append the new user message, send the full history to the AI API, and append the AI response before saving it back. This keeps context across the full conversation without a database. The route covers this pattern in step 8 with full working code.
