What does this workflow do?

Drop your image — the pipeline runs 3 automated steps: Pillow (image→image) → LLM Reasoning (image→text) → Pillow (image→image) — and delivers image. Every node is visible, auditable, and replaceable.

System flow

1. Pillow — Image pre-processing — deskew, denoise, crop and normalise before analysis 2. LLM Reasoning — Large-language-model step that extracts, classifies, validates or writes structured output 3. Pillow — Image pre-processing — deskew, denoise, crop and normalise before analysis

FlowSync proprietary

How is this different from n8n or Zapier?

Unlike generic workflow builders, FlowSync workflows ship pre-configured with AI skills baked into every node — OCR, LLM reasoning, transcription, super-resolution — not just webhook triggers. Each node is white-box auditable: you see input, output, and config. Deployment is instant — no self-hosting, no API-key per node.

Use cases

  • YouTube thumbnail production
  • Course video preview images
  • Social media video covers
  • Livestream highlight thumbnails
