Someone built a TikTok slideshow factory that runs on $5 and a Pinterest account. Here is the exact 4-step pipeline. STEP 1: Scrape Pinterest instead of generating everything. 500 to 1000 images per aesthetic. Tagged by mood, color, subject. Stored in Supabase. This is the cost killer the whole system is built around. STEP 2: Drop 10 viral slideshow screenshots into Codex GPT-5.5. It reverse-engineers the format into a reusable JSON schema. Hook. Setup. Payoff. CTA. Visual layout. Build 20 to 30 schemas and you have infinite variation templates. STEP 3: Hybrid image generation. Slide 1 (hook) = ChatGPT Images 2.0. Custom scene. Full AI. Slides 2 to 6 = Pinterest image plus local text overlay. Slide 7 (CTA) = Pinterest or reused template. Result: 1 AI image instead of 7. Cost drops 85%. Visual quality often goes UP because human-curated beats AI-generated for aesthetic content. STEP 4: Post via Postiz. Self-hosted. Official TikTok Content Posting API. 3 to 5 posts per account per day. Staggered across accounts. The whole pipeline runs without you touching it. Note: GPT-5.5 is not on API key auth yet as of April 2026. Use GPT-5.4 API until rollout if you want fully autonomous. Bookmark this.(CyrilXBT)
