Information Gain

A semantic analysis tool that measures how original your ideas actually are. Enter a topic, write your thesis, and the app fetches the internet’s consensus via Brave Search, vectorizes both texts locally in the browser using Transformers.js, and computes a composite originality score — cosine similarity, Jaccard index, and a negation heuristic for detecting genuine contrarian positions.

The entire pipeline runs client-side. Embeddings are computed in a Web Worker via a quantized MiniLM model. Knowledge nodes persist in SQLite WASM with a Voy sidecar for vector similarity search. Scores range from “Absolute NPC” to “Complete Wildcard” — the internet consensus is waiting to humble you.
