Biggest opportunity: Swap “grammar” for “spellcheck”. “grammar” isn't earning its slot: you're not in the first 24 results for its own search. “spellcheck” sits at #16 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active

At least 2K of 53.4K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,771 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 4.0.38, well behind 6.8.

    You will find the settings in your USER Profile! (Not the first section, where I would seach for it…) I’m just curious: Does the plugin submit every post to an external server for spell checking or is this a completely local process?

    Everything worked great but it kept adding ” ” throughout my article’s HTML which I had to go back and delete.

    This screwed up all the code as well as other plugins. It screwed up spacing with a <span> tag listed every other word for nonexistent errors. AVOID THIS PLUGIN!

    Hi Matthew, thanks a lot for making this plugin available, because as you can see English is not my mother tongue and yet an need to write in it. So, thanks a lot for this plugin. I hope my blog will have less spelling errors from now on and less than this review 😉 [ link redacted, please do not post links in reviews ] So thanks again!

    Great to have a non-Jetpack spellchecker and the basic functionality works great. However since 3.9, the spellchecker leaves all kinds of < span class=”hiddenSpellError” > references in the HTML, the moment you switch it on; bloating the code, breaking shortcodes and embeds and much more. Therefore currently unusable unless you remove all of these Spans manually, which is a ton of work as all unknown words are marked as well.

    The plugin stopped working properly some time ago with important erros. It breaks all shortcodes, oEmbed and leave your content full os <span> elements. The problem was posted in the support forum but there is no reply from the author. See https://wordpress.org/support/topic/since-wp-v39-span-classes-are-added-in-the-code
