Import in n8n: Workflows → ⋯ → Import from file, then add your credentials. Free to use — no signup needed.

How it works

Telegram Trigger receives the message — the workflow fires on every incoming Telegram message via webhook.
The AI Agent reads the message — it takes the message text and sends it to the chat model with a Telegram-friendly system prompt.
OpenAI generates the reply — gpt-4o-mini writes the answer (cheap and fast; swap it for any model).
Window Buffer Memory keeps context — the last 10 messages are remembered per chat, keyed by Telegram chat ID, so every user gets their own continuous conversation.
Send Reply posts the answer — the agent’s output is sent back to the same Telegram chat.

You’ll need:

n8n (self-hosted or cloud) with webhook access
A Telegram bot token — message @BotFather on Telegram, send /newbot, and copy the token it gives you
An OpenAI API key — get one at platform.openai.com → API keys

Download the workflow JSON using the download button on this page.
In n8n, go to Workflows → ⋯ → Import from file and select the JSON.
Create your Telegram credential — in n8n go to Credentials → New → Telegram, paste your bot token, and save. Then open the Telegram Trigger node and the Send Reply node and select your credential in each.
Create your OpenAI credential — in n8n go to Credentials → New → OpenAI, paste your API key, and save. Then open the OpenAI Chat Model node and select your credential.
Activate the workflow (toggle, top-right), then send your bot a message on Telegram.

Change the model — open the OpenAI Chat Model node and pick gpt-4o or any other model.
Change the personality — edit the system message in the AI Agent node.
Longer memory — raise Context Window Length in the Window Buffer Memory node.
Restrict access — add an IF node after the trigger checking {{$json.message.chat.id}} against your own chat ID, so only you can use the bot.
