AI Content Automation System–Make.NotionMetricool Integration

I need an automation expert to build a multi-brand AI-powered social media workflow that runs from idea generation to content scheduling with minimal manual effort.
Everything must be orchestrated inside Make.com, connecting ChatGPT / Claude, Notion, Google Drive, Canva Pro, Metricool, Lex, and Otter.ai.

What I Want Built
1️⃣ Idea Engine
Aggregate content ideas automatically from Reddit, X/Twitter, YouTube transcripts, RSS feeds, Latestly.ai, Otter.ai, and trending hashtags.
Use AI to output structured ideas (Hook, Summary, Format, CTA, Score) to a Notion database.
Send Slack/email alert when new ideas are ready.
2️⃣ Content Factory
Triggered when a Notion idea is approved.
Generate long-form post, short-form video script, and carousel outline using ChatGPT/Claude.
Polish via Lex, auto-design with Canva API, store outputs in Drive, update Notion, and alert reviewer.
3️⃣ Repurpose & Schedule Engine
Convert approved drafts into platform-specific posts (LinkedIn, Instagram, TikTok, YouTube, X, WhatsApp).
Schedule automatically with Metricool.
Pull analytics weekly and feed results back into Notion to spark new ideas.
4️⃣ Video Add-On
Extend workflow using HeyGen + ElevenLabs to produce short AI videos and thumbnails automatically.
