Text Similarity (In-Browser AI)
AIRuns On Your DeviceCompare two texts for meaning similarity with sentence embeddings — MiniLM running in your browser, no uploads.
First use downloads a quantized model, cached afterwards — later sessions work offline. Your text is never uploaded.
Text Similarity Checker — Semantic AI in Your Browser
Paste two texts and see how similar they are in meaning — useful for spotting duplicate support tickets, near-duplicate product descriptions, paraphrased answers, or checking whether two drafts say the same thing. A MiniLM sentence-embedding model scores the pair from 0 (unrelated) to 100 (same meaning), with an honest verdict label.
The model (~23 MB, quantized) downloads once and runs locally in your browser using WebGPU or WASM — your text is never uploaded. This measures semantic similarity, not word-for-word overlap: "A man plays a guitar" and "Someone plays an electric guitar" score high even though almost no words match.
