Where we diverged: WebVideoCreator was built against the old headless mode on the main chrome binary. Since then, Chrome split the old headless mode into a separate chrome-headless-shell binary with a different API surface (starting with Chrome 120, fully removed from the main binary in Chrome 132). We also needed tighter integration with our cloud infrastructure (Cloud Run, GCS uploads, Datadog tracing), stricter security (SSRF protection for rendering untrusted URLs), and more control over the video element pipeline and audio extraction. So we rewrote it in TypeScript with modern Puppeteer and adapted the architecture for our deployment model.

The “Knocking on Wood” Wikipedia page mentions Roud’s conclusion, and this claim of a 19th century origin has circulated online as the final say on the matter.

For the web version’s accuracy, I tested different feature limits. I prioritized performance and kept 500k features—stored as JSON, it’s 107MB (though gzip on server reduces it to ~38MB). I tried smaller versions (50k, 80k)—accuracy only dropped 3–4%, but final AI detection rates varied significantly, especially for human texts, with relative errors up to ±50%, leading to false positives. So I stuck with 500k.
