Dropbox Note Summarizer: Groq to Notion & Google Sheets

Turn a Dropbox Markdown note into a Notion page—with Groq-powered summarization and Slack confirmation

This n8n workflow pulls a Markdown note from Dropbox, summarizes it using Groq Chat (OpenAI gpt-oss-20b) with a strict JSON output, saves the results to Notion, logs a backup in Google Sheets, posts a Slack status message, and then archives the processed file back in Dropbox.

What this workflow does

• Manual start: You run the workflow manually inside n8n.
• Dropbox download + parsing: It downloads a specific Markdown note (e.g., /Notes/sample.md), converts the binary into text, and captures filename, MIME type, and a timestamp.
• Groq summarization (JSON-only): The note text is sent to Groq Chat (model: gpt-oss-20b) to generate:
  • a JSON-only title
  • a summary
  • exactly five tags
  It also validates the response against a strict schema.
• Notion page creation: It maps the AI output into a structured record and creates a new page in a Notion database using note metadata, summary, and Tags (multi-select).
• Google Sheets tracking: It appends a tracking row with the processed note details for backup/auditing.
• Slack notification + Dropbox archive: It posts a Slack message with processing status and the Notion page reference, then moves the original file from /Notes/ to /Processed/.

Use cases

• Convert daily research or meeting notes stored as Markdown in Dropbox into searchable Notion entries.
• Maintain a lightweight audit trail in Google Sheets whenever notes are processed.
• Keep teams informed via Slack whenever a summary has been saved to Notion.
