Paste a function or snippet in any common language. The structural breakdown below is instant, deterministic, and always accurate about what it detects — no download, no AI, no upload. There's also an optional experimental AI mode further down if you want a plain-English summary attempt.

🧪 Try AI explanation (experimental, on-device)

Downloads a real small AI model to your device and asks it to summarize the code in plain English. Click to expand.

⚠️ Experimental. This downloads and runs a genuine (small) AI model locally in your browser — it never uploads your code anywhere. Small models can misread or invent details, especially on long, obscure, or multi-file code. Treat the summary as a starting point, not ground truth, and always sanity-check anything important. The structural breakdown above is more reliable for exact facts.

Not loaded yet. First load downloads the model once; it's cached by your browser after that.
