You're comparing paper-skimming and structured-summary assistant (Scholarcy) to local-first reference library and citation manager (Zotero) — different categories (Paper tools vs Reference manager). The surfaces do not line up either (app vs API vs local). Little overlap on modalities or tracked capabilities. The stat bars still run — use this read for budget and privacy, not feature parity.
