This is a Telegram bot that uses:

• OpenAI's ChatGPT, obviously, as "the brain"
• LangchainJS to constructs prompts, handle convo history and interact with Google
• OpenAI's Whisper API to generate text from voice
• Play.ht to generate voice from text and reply to voice messages

Prerequisite: You need Node 18, a Telegram bot token and an OpenAI API key with access to GPT-4. Optionally you can use other model by setting OPENAI_MODEL env var. Ask ChatGPT how to get these. You'll also need ffmpeg installed to use voice interactions.

1. git clone https://github.com/RafalWilinski/telegram-chatgpt-concierge-bot
2. cd telegram-chatgpt-concierge-bot
3. touch .env and fill the following:

TELEGRAM_TOKEN=
OPENAI_API_KEY=
PLAY_HT_SECRET_KEY=
PLAY_HT_USER_ID=
PLAY_HT_VOICE= # check docs for available voices https://playht.github.io/api-docs-generator/#utra-realistic-voices
OPENAI_MODEL=gpt-3.5-turbo # only if you don't have access to GPT-4
#SERVE_THIS_USER_ONLY=99999999 # uncomment this if you want to only serve this user id. The ID will be printed on stdout.

4. npm install
5. npm start
