It retrieves a note, extracts its content, and uses AI to generate a meaningful title, concise summary, and five relevant tags. The processed note is then saved to Notion, logged in Google Sheets for tracking, and a Slack notification is sent to confirm successful processing. Finally, the original file is moved to a Processed folder in Dropbox, ensuring each note is handled only once while maintaining an organized and searchable knowledge base.\n\n### Workflow Highlights:\n\n- Downloads Markdown notes from a Dropbox folder.\n- Uses AI to generate a title, summary, and 5 relevant tags.\n- Validates AI output with a structured JSON schema.\n- Stores processed notes in a Notion database.\n- Logs note details to Google Sheets for backup and reporting.\n- Sends a Slack notification after successful processing.\n- Archives processed notes by moving them to a Dropbox Processed folder.\n- Creates an automated, searchable note management workflow with minimal manual effort.\n\n### Quick Setup:\n\n- Connect your Dropbox, Groq (LLM), Notion, Google Sheets, and Slack credentials.\n- Update the Dropbox source and processed folder paths.\n- Select your Notion database and Google Sheets document.\n- Choose the Slack workspace and channel for notifications.\n- Review or customize the AI prompt and model (optional).\n- Run the workflow to verify everything is working, then activate it for regular use."
