Story DNA Comparison Tool (Plugin + Guided Workflow)

A browser-based tool that writers paste their premise into, then systematically compares it against a curated database of 10,000+ published book/film premises using semantic similarity matching (not keyword matching). The tool returns a ranked list of 'closest comps' with a visual breakdown showing which story elements (character archetypes, plot structure, setting, theme) overlap vs. diverge, plus a 'Originality Score' (0-100) with specific guidance on which elements to modify or amplify. Writers see exactly what's been done and what hasn't in under 10 minutes.

Original Problem

Writers paralyze themselves with originality anxiety before starting projects

Aspiring and working writers obsess over whether their story ideas are original enough, causing them to delay or abandon projects entirely. They lack a practical framework to evaluate originality realistically, leading to endless second-guessing and comparison paralysis. Existing writing communities offer vague reassurance rather than concrete methods to move forward despite originality concerns.
