Telegram Voice Note transcribe to Google Doc + Summary document

This n8n workflow automates the process of transcribing a voice message received via Telegram, summarizing the transcription using an AI model, and then saving both the transcription and the summary to separate Google Docs in Google Drive.

Here's a breakdown of the workflow:

* Telegram Trigger: The workflow is initiated when a new message is received on Telegram.

* Telegram Node: It retrieves the voice message file from Telegram using the file_id from the incoming message.

* OpenAI Node: The retrieved voice file is then sent to OpenAI for transcription.

* Google Drive (for Transcription): The transcribed text is saved as a new Google Doc with the current time as its name in a Google Drive folder named "N8N Transcribes".

* AI Agent: The transcribed text is sent to an AI Agent (connected to a DeepSeek Chat Model) to generate a plain text summary. The prompt for the summary is set to "Generate A summary description from this Telegram message. Don't use or anything that emulates rich text. The description should be in plain text Expand on the title so that the description can be used in a report to my supervisor. Only provide one summary. Do not label it *Summary****, I already know it's a summary. Thanks.:{{ $json.text }}".

* Google Drive (for Summary): The generated summary is then saved as a new Google Doc with the current time as its name in a Google Drive folder named "N8N Summaries".

In essence, this workflow allows users to send a voice message to a Telegram bot, and automatically get both a transcription and a summary of that message saved as separate documents in their Google Drive.
