Spellmatic is a WordPress Plugin Directory app by Cary Molyneux.
AppRanks verdict
Generated from live marketplace data — refreshed daily
Spellmatic is a newly-listed WordPress app with a limited review volume. Category data on the canonical marketplace listing is currently incomplete, so AppRanks falls back to platform-wide rather than category-relative comparison for this listing. no published reviews yet means feature claims are unverified by the wider merchant base. Without a published review base, the only fit-signal available is the developer's own documentation plus the marketplace's listing-quality audit (linked below). Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
Pros
- +Published by Cary Molyneux — established developer track record
Cons
- −No public reviews yet — fit and reliability are unverified

Privacy First The free tier uses Harper WASM — a blazing-fast, privacy-respecting grammar engine that runs entirely in your browser (client-side WebAssembly). Zero external API calls. Zero data sent anywhere. Your content stays yours.
The optional BYOK AI layer uses your own API key. Your key is stored encrypted on your server and all API calls go directly from your server to your chosen AI provider — Spellmatic never sees your content or your key.
External Services This plugin connects to the following third-party services. Full details are also available on the Open Source & Services page inside the plugin (Spellmatic → Open Source).
Grammar Engine — Harper (Bundled) The Harper grammar engine (Apache 2.0 licensed) is bundled with the plugin and runs entirely in your browser. No external connections are made during scanning.
You may optionally update the grammar engine to get improved dictionaries and grammar rules. No external connections are made by the plugin for grammar engine updates — all updates are performed manually by the site administrator:
Download the latest harper.js from the Harper npm package at https://www.npmjs.com/package/harper.js — the file is located in the dist/ folder of the package.
Upload the file to wp-content/uploads/spellmatic/harper.js on your server (create the spellmatic folder if it does not exist).
The plugin will automatically detect and use the uploaded file on the next page load.
To revert, simply delete the file from wp-content/uploads/spellmatic/ — the plugin will fall back to the bundled version.

AI-Powered Grammar Analysis (Optional, BYOK) When you enable the BYOK AI feature and initiate an AI scan, post and page text is sent to your chosen AI provider for contextual grammar analysis. This only occurs when you explicitly click “Scan” with AI enabled. API keys are encrypted with AES-256-CBC and stored on your server.
