Generate multi-slide carousels for LinkedIn, Instagram, Threads, and TikTok using AI copy and design. Start from a topic or your knowledge base, refine in a canvas editor or AI chat, then publish directly to your connected accounts.

​
Pipeline

1

Generate copy

Provide a topic, URL, or knowledge base. AI produces slide titles, body text, and CTAs optimized for your target platform. Cost: 15 credits.
2

Generate design

AI builds full slides from your copy. Choose Template mode (structured layouts) or AI design mode (fully generated design). Cost: 15 credits.
3

Refine

Edit in the canvas editor or send natural-language instructions to refine individual slides without regenerating the full deck. Cost: 10 credits per refinement.
4

Export and publish

Export slides as PNG/JPEG, upload assets, and create a scheduled post draft — entering the standard publishing pipeline.
curl -X POST https://app.autoposting.ai/api-proxy/carousels/generate \
  -H "Authorization: Bearer sk_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "topic": "5 reasons to automate your social media",
    "platformPreset": "linkedin",
    "slideCount": 7,
    "brandSlug": "brand_slug"
  }'
