Transcribe & summarize Telegram voice notes with OpenAI and DeepSeek Chat to Google Docs

This workflow automates the process of transcribing voice notes from Telegram and then summarizing them, finally saving both the transcript and the summary to Google Drive.

Here's a step-by-step breakdown of what the workflow does:

• Triggered by Telegram Message: The workflow starts when a new message is received on Telegram.
• Get Audio File from Telegram: It then retrieves the audio file from the Telegram message.
• Transcribe Audio with OpenAI: The audio file is sent to OpenAI for transcription.
• Save Transcript to Google Drive: The generated transcript is saved as a new Google Doc in a designated "N8N Transcribes" folder within Google Drive. The document is named after the original audio file.
• Summarize Transcript with AI: The transcript is then sent to an AI agent (which uses DeepSeek Chat Model 1 as its language model) to generate a summary description. The prompt instructs the AI to create a plain text summary suitable for a report to a supervisor, expanding on the title and avoiding rich text formatting.
• Save Summary to Google Drive: Finally, the generated summary is saved as a new Google Doc in a "N8N Summaries" folder in Google Drive, also named after the original audio file.
