Score a submission to see the breakdown.
Frequently asked
- How does the spam score work?
- It's a deterministic heuristic: keyword blocklist, URL/link density, excessive capitalization, content entropy (gibberish detection), suspiciously short bodies, and HTML/script injection attempts. Each signal adds points toward a 0–100 score.
- Does it send my data anywhere?
- No — the scorer runs entirely in your browser. Nothing is uploaded.
- Is this what FormLoom uses on real submissions?
- Yes — this is the exact heuristic scorer FormLoom runs on every submission by default. When an LLM key is configured, FormLoom adds AI classification on top, with this heuristic as the always-available fallback.
- Can I stop spam without a CAPTCHA?
- Yes — honeypot + this AI spam score catches most spam without a CAPTCHA wall that hurts conversion. You can still add Turnstile or hCaptcha per form if you want.
