Convert Telegram voice notes into markdown journals with Groq Whisper and Gemini

Description

Telegram Voice Notes to Markdown Journal with Groq Whisper and Gemini

This workflow transforms Telegram voice notes and audio files into clean markdown journal entries using Groq Whisper, CloudConvert, and Google Gemini.

It automatically downloads incoming Telegram audio messages, transcribes them with Groq Whisper, cleans the transcript into a readable reflective journal using Gemini, converts the result into a markdown file, and sends the journal back to Telegram.

For better audio compatibility, the workflow also includes a CloudConvert fallback path. If Groq Whisper rejects the original audio file because of container or codec issues, the workflow converts the audio to MP3 with CloudConvert and retries transcription automatically.

An optional Google Drive section can also archive all generated journals automatically.

This workflow is useful for journaling, voice-based note-taking, personal reflection, idea capture, daily logging, and building a lightweight AI-assisted second brain.

Setup steps

Connect your Telegram credentials
Open the Transcribe Audio with Groq Whisper node
Replace the placeholder Authorization header with your Groq API key
Install the verified CloudConvert community node if it is not already installed
Connect your CloudConvert credentials for the MP3 fallback path
Connect your Google Gemini credentials
(Optional) Connect your Google Drive credentials
Test the workflow manually with a Telegram voice note or audio file
Activate the workflow
Send a voice note or audio file to your Telegram bot

CloudConvert Audio Compatibility Fallback

The CloudConvert path is included to improve reliability with different audio uploads.

Groq Whisper supports common audio formats, but some files may still fail because of unusual containers, codecs, MIME types, or metadata. When that happens, this workflow converts the failed audio file to MP3 with CloudConvert, then sends the MP3 back to Groq Whisper for transcription.

This fallback is especially useful for some uploaded M4A, OGG, OPUS, or recording files that may not be accepted directly.

If you only want to support files that Groq accepts directly, you can disconnect the CloudConvert fallback path.

Optional Google Drive Backup

The Google Drive section is fully optional.

If connected:
The workflow searches for a Personal Journal (n8n) folder
Creates the folder automatically if it does not exist
Uploads generated markdown journals automatically

If you do not want cloud backups, simply disconnect the Google Drive section.

Notes

This workflow uses:
Groq Whisper (whisper-large-v3) for transcription
CloudConvert for optional audio-to-MP3 fallback conversion
Google Gemini for transcript cleanup and journal formatting
Telegram Bot API for message delivery
Markdown file generation for portable journaling

The AI prompt is designed to:
Preserve the speaker’s original meaning
Keep the natural reflective monologue style
Improve punctuation and readability
Avoid summarization or hallucinated content

The generated markdown journals can easily be imported into note-taking tools such as Obsidian, Logseq, Notion, or any markdown-based system.
