What’s New

Coherence Scorer — scores logical flow between adjacent sentences using mean cosine similarity (Semantic assist) or keyword-overlap Jaccard (heuristic fallback). Sentence-pair breakdown table sorted by weakest pairs first.

• Coherence Scorer

Outlier Sentence Detector — embeds all sentences, computes the topic centroid, and flags the bottom quartile by cosine-distance as potential off-topic or padding candidates. Copy-out of flagged sentences included.

• Outlier Sentence Detector

Relevance Scorer — scores query–passage topical alignment via embedding cosine similarity mapped to 0–100. Keyword-overlap Jaccard fallback when Semantic assist is disabled. URL fetch supported.

• Relevance Scorer

AI Content Detector now blends multi-signal heuristics (lexical diversity, sentence uniformity, repetition, AI-phrase density) with an optional dual-anchor embedding assist — toggle Semantic assist on the tool page; stays fully local when disabled.

• AI Content Detector

API POST origin checks accept any-port localhost in dev and the default production origin on Vercel, fixing false 403 Forbidden on custom domains and preview hosts.

API routes now read JSON bodies with a strict byte cap (DoS mitigation) instead of unbounded req.json().

Outbound URL helpers enforce a maximum URL length; multi-URL checks reject overlong strings early.

Fetch/headers/redirects error responses avoid leaking raw low-level exception messages for unknown failures.

Public brand HSL env vars are validated so unsafe tokens cannot slip into CSS custom properties.

PostCSS bumped and npm overrides pin a patched glob (supply-chain advisories in the dev/tooling graph).

Windows: npm run clean retries removal of .next so a half-deleted cache (and missing vendor chunks in dev) is less likely.

Shipped a What's New page so every release notes update lives in one visible place.

Site and footer now show the app version from package.json (semantic versioning).

Tool cards and tool pages can display highlight ribbons: New, Hot, Trending, and Updated for noteworthy modules.
