One-Click Dataset Preparation Agent
Upload a ZIP of raw game assets or manga scans. Our agentic pipeline automatically extracts characters, tags every sprite, filters truncated images, and packages a LoRA-ready dataset — all in a single job.
Upload ZIP
Drop a ZIP archive of raw sprites, game screenshots, or manga panels — any size, any mix of formats.
Agent Processes
The pipeline detects truncated images, clusters characters, extracts sprites, and auto-generates Danbooru tags in sequence.
