Every aggregate figure on PlainSpell is counted from the live database. This page lists what you can download or cite today, under what license, and what would be required to diversify revenue beyond the current ad path. Documentation only; nothing here activates a paid product.

Revenue readiness (not activated)

This section documents what is already productized and what would be required to diversify beyond display ads. Nothing here launches a paid API, affiliate program, or alternate ad network. Every activation step is marked [operator].

Already productized

  • CSV download at /data/plainspell-corpus-statistics.csv (live DB counts).
  • Dataset JSON-LD on /statistics and this page (Google Dataset Search / passive citability).
  • Per-entity Markdown exports on word, confusable, homophone, and statistics routes.
  • CiteThis blocks and shareable OG images on entity pages (passive citability, no outreach).
  • Mediavine Journey display ads are active on approved inventory; AdSense account is in GETTING_READY review queue.

Affiliate slot rules (IF ever activated)

PlainSpell is a language-reference corpus, not tutoring or exam-prep advice. An honest affiliate test would only be considered on non-advice utility surfaces (for example dictionary apps or style-guide tools linked from the tools hub), never adjacent to YMYL spelling guidance, methodology prose, or entity verdict bands. Rules if activated: clear FTC disclosure next to every link; ranking order unchanged by payout; Module 36 density ceilings shared with ads; self-serve network only. [operator]: not applied.

Alternative ad network eligibility (paperwork only)

Mediavine Journey is already serving on this domain. A second network would require non-competing inventory rules and operator review. A paid data-licensing or API tier would need separate pricing, terms, and rate limits documented here before any keys ship. [operator]: no alternate network code or paid API filed from this note.

Activation checklist (all [operator]): pricing/terms for any paid data API · affiliate network application · second ad-network inventory split · any new ad script beyond the existing Journey path.
