A professional web utility for AI filmmakers, directors, and designers. Automatically detect panel boundaries, lock frames to 16:9 or 9:16 aspect ratios, edit labels in-canvas, and batch export your storyboards in seconds.
StorySplitter AI is a free, serverless web application engineered for AI filmmakers and visual artists to extract, aspect-lock (16:9, 9:16), and batch-export individual panels from Midjourney, Stable Diffusion, and Flux storyboard sheets. It processes 100% locally in-browser with zero server uploads and full offline security.
Drag & drop one or multiple storyboard images here, or click to browse
Drag and drop your AI-generated sheets from Midjourney, Stable Diffusion, or pencil sketches into the browser.
Run boundary auto-detection, adjust aspect locks (16:9 for film, 9:16 for shorts), or customize grid alignment.
Name your sequence, optionally burn labels onto images, and export all cropped panels as high-resolution PNGs or JPEGs.
Detect borders and drawings dynamically. Our smart computer vision model learns from your corrections to recommend optimal thresholds.
Instantly lock crops to standard cinema formats (16:9) or vertical smartphone formats (9:16). Or, resize panels freely.
Your work is completely secure. No files are uploaded to any server; everything processes locally in your browser. Works offline.
Export entire work sessions as a .storysplitter bundle. Drag it back in to resume edits with full undo/redo stack recovery.
