Create narrated Google Slides videos with Gemini TTS, Shotstack, Slack, and Drive

Quick overview Turns Google Slides speaker notes into a narrated video and re-voices only the slides that changed. A Gemini agent checks each slide against its notes and proposes pronunciations for a reading dictionary. Gemini TTS voices it, Slack approves it, and Shotstack renders captioned MP4s to Google Drive. How it works Starts from an n8n Form submission (with a Google Slides URL and options) or a weekday 8:00 schedule run. Loads the Google Slides presentation, fingerprints each non-skipped slide (including speaker notes and voice settings), and compares it to previously stored slide records in an n8n Data Table to identify which slides changed. For each changed slide, fetches a thumbnail, uses a Google Gemini agent to rewrite speaker notes into a narration script and flag issues, and looks up pronunciations in an n8n Data Table dictionary tool.
