Stop writing social captions by hand. Drop images into a Google Drive folder, and these three n8n workflows post them automatically to LinkedIn, Facebook, and Instagram — each with a unique, on-brand caption written by Gemini Vision based on what's actually in the image.What's included:- LinkedIn Auto-Poster (native LinkedIn REST API — image upload + publish, the fiddly 2-step upload flow already solved for you)- Facebook Auto-Poster (Facebook Graph API)- Instagram Auto-Poster (official Graph API 2-step media flow, no community node)- Full setup guide (credentials, LinkedIn URN lookup, Facebook/Instagram IDs)- Editable AI prompt — tune the writing style to your brand in one field, no need to touch the Gemini nodeRequirements: a self-hosted or n8n Cloud instance, Google Drive, a free Gemini API key, and LinkedIn/Facebook/Instagram developer app access.Why this instead of building it yourself: LinkedIn's native posting API requires a 2-step image upload most tutorials skip — this template has that already wired and tested.
