From Google Drive to Social Media: Fully Automated AI Workflow

TL;DR

Upload photos to Google Drive and Make.com, N8N, or Claude Code automatically generates captions and posts them to LinkedIn, Instagram, or Facebook.

Key Points

• 1.The core workflow has four steps. Google Drive detects a new image, downloads it, sends it to OpenAI or Claude for caption generation, then posts to social media via Blotato — all without manual input.
• 2.Make.com is the recommended starting point for beginners. Connect Google Drive, add an OpenAI API key from platform.openai.com (separate from ChatGPT), and add Blotato via its settings API key to establish all three connections.
• 3.The system prompt is the biggest leverage point for quality. Adding business context — your offer, a CTA like a phone number or website, preferred tone, hashtag preferences — dramatically improves caption specificity versus a generic prompt.
• 4.Posting frequency is controlled by two parameters. The 'limit' field sets how many images are processed per execution cycle, and the scheduler (e.g. every 15 minutes, daily at midnight, or specific weekdays) controls when the automation runs.
• 5.N8N offers parallel branch execution that Make.com lacks. In N8N, binary image data can simultaneously feed the Claude image-analysis branch and the Blotato media-upload branch, then a merge node combines the caption and image URL before posting.
• 6.Blotato supports Instagram, Facebook, TikTok, and LinkedIn from one API key. Switching platforms requires only changing the account selector and post-type parameter (e.g. setting post type to 'story' for Instagram Stories).
• 7.A Claude Code custom web app adds a human-approval layer. Users drag and drop an image, review and edit the AI-generated caption in a GUI, then click one button to post — avoiding unreviewed auto-publishing and enabling multi-employee access.
