Quilty, an AI startup that scores film scripts for commercial success, has faced skepticism after predicting a box office flop would outperform an Oscar-winning blockbuster.

Founded by film producers Simon Horsman and Daniel Wood, Quilty uses AI to analyze scripts and generate reports that assign a score from 0 to 100 reflecting narrative quality, commercial viability, audience resonance, and estimated production cost. The platform combines multiple widely available AI tools—Gemini for structure analysis, DeepSeek for financial modeling, and Claude and ChatGPT for narrative and character analysis—rather than training a single proprietary model.

When users upload scripts, Quilty's system outputs detailed reports within minutes, including estimated budgets, story beat outlines, and character analyses. The service costs $50 per individual analysis, with discounted rates available for multiple analyses.

The platform predicted the script for Christy would outperform the script for Sinners—but Christy ultimately grossed around $2 million while Sinners grossed $370 million. Quilty's founders attributed the mismatch to the platform's focus on Sydney Sweeney's star power and production cost differences, but acknowledged that Quilty cannot foresee unforeseen factors such as actor controversies or unexpected cultural phenomena that affect a film's financial performance or audience reception.
