ChatGPT Telegram Bot

A pet project for integrating ChatGPT into Telegram with two launch modes: via Bot API as a bot or via MTProto as a user. The bot supports live response updates, dialog history, system prompts and RU/EN localization.

Open project

Inside

  • Two modes: as a Telegram bot or as a user through MTProto.
  • `/system`, `/history` and `/clear_history` commands for behavior and context control.
  • The answer is updated in real time by editing the message, with configurable update interval.

Product view

ChatGPT Telegram Bot

The interface works directly inside Telegram: the user sends a prompt, the bot progressively updates the answer message, and in history mode it includes previous dialog context. This makes the project feel less like a one-off command bot and more like a full chat assistant inside a familiar messenger.

Functionality

Features

Bot API and user mode

The project can run as a regular Telegram bot through a BotFather token or as a user client through API_ID/API_HASH and MTProto authorization.

System behavior

The `/system` command changes assistant behavior: for example, translator, editor or domain assistant modes.

Dialog history

`/history` enables chat mode with previous messages included; `/clear_history` forces stored context cleanup.

Token limits

`MAX_MSG_TOKENS` controls the maximum tokens sent to the model: message history plus the new request.

Workflow

User flow

  1. 01

    Choose launch mode

    Bot mode requires a BotFather token, while user mode requires API_ID, API_HASH and a Telegram phone number.

  2. 02

    Add OpenAI API key

    The key and Telegram settings are added to the `docker-compose.yaml` environment.

  3. 03

    Run with Docker

    Basic launch uses `docker-compose up -d`; user mode additionally requires `node tglogin.js` and pm2 restart.

  4. 04

    Configure in Telegram

    After launch, behavior and history are controlled by commands directly in the chat.

Under the hood

Technical side

Telegram integration

`node-telegram-bot-api` is used for bot mode, `@mtproto/core` for user mode.

OpenAI streaming parser

`eventsource-parser` helps process response streams and update the message while text is generated.

Localization and config

RU/EN localization is controlled by `APP_LOCALE`; model version is switched through `MODEL_VERSION`.
