Auto-Caption & Auto-Post Videos to Instagram & TikTok

This n8n workflow streamlines short-form video content creation and distribution. It triggers on new video uploads to a Google Drive folder, uses Submagic API to automatically add styled captions, polls for completion, downloads the enhanced video, generates optimized captions with OpenAI, uploads to Postiz for scheduling/posting to Instagram and TikTok, and logs all details including video links, captions, and status into a Google Sheet.

Benefits include hands-off automation from raw video to published post, ensuring engaging visuals with AI-styled text, brand-consistent captions, and centralized tracking for performance analysis. It saves hours of manual editing and posting, ideal for content creators, marketers, and agencies scaling social media presence.

Use cases: Daily Reels/TikTok production for e-commerce brands promoting products, influencers automating content pipelines, or marketing teams handling viral video campaigns. Requires Google Drive, Submagic API, Postiz, OpenAI, and Google Sheets setup for seamless operation.
