My website exceeded word usage quota. What does it mean?

Both the Free and Pro versions of the plugin have usage limitations. One of them is the aggregated number of words checked during a certain period.

The Free version is limited to 10,000 words for a single website aggregated for all users per day. Once the aggregated usage for a website exceeds this number, the plugin stops checking text until the next day (00:00 UTC-0) and the next error message will be shown on the plugin’s settings page: “Word usage quota for the free plan exceeded. Contact support for more details.“

Below is the example explaining how the usage is calculated. The plugin doesn’t run in a background or doesn’t generate false data usage. If the plugin is enabled, it works only when a page or blog post is in the editing mode.

Let’s assume you have a page which contains 1000 words. You open it for editing and this is when the plugin starts. All the text from this page will be sent for checking. Thus, 1000 words are checked and recorded as usage. You still continue editing, let’s say you decided to make some changes in the 2nd paragraph which contains 100 words. Since there were some changes, the plugin needs to recheck this part. As a result extra 100 words will be sent for checking. We can’t send individual words as checking relies on sentences. So, now 1100 words are recorded in usage. Later you decide that you want to save the page as a draft and preview changes. After previewing changes, you decide to go back to editing and open the page for editing again (again this is when the plugin starts). The plugin doesn’t know that this is the same page and does rechecking again. As a result plus 1000 words are added to the general statistics. The total is now 2100 words. Also, let’s imagine that while editing mode is ON you have to reload a page a few times, the whole page will be rechecked after each reload of the page or browser.

It says the free version only handles up to 6 lamguages, and I only wanted a simple basic spellchecker for and English blog. Installed yesterday and it just worked, pretty simply, a lot like Microsoft spellcheckers with the words underlined and click on them for suggested spelling. However that was yesterday - today it tells me I have reached the trial limits! So its not a free version, its a 1 day limited trial...

I tried a different plugin first and was shocked when it left highlighted text on my published page simply because it didn't have British English! This plugin does understand British English and highlights unknown and misspelt words simply with a red underline. I like it!

Installed the plugin, navigated to the settings page to make sure all relevant post types were checked, and... nothing. I literally have NO idea what this plugin actually does, or how it is supposed to work. Post and page edit screen show absolutely nothing. Seems to me this is a bit of a half-baked and not very well coded plugin. No offense to the dev team, but really: if your basic version of the plugin doesn't even work properly, it might be a good idea to leave the option of buying a premium version off the table - at least until such a time that you've fixed ALL relevant bugs. Not good for business selling something which is clearly broken - take some advice from a veteran plugin developer. I'll just code my own, but for what it's worth: WordPress 5.8.2, using Blogable theme, PHP v7.4 (ea-php74) Thanks.

I need it for my Blog in German, even if i have changed it to German in the Settings it swaps German Words with English Words. No sense in using it for my German Website then. If you cannot manage it to use it in German don't offer it.

This installs a settings panel, but no spell check tool shows up. It wasn't clear how to run a spell check on the site. I looked through the documentation which covered architecture, hardware requirements, configuration, and other confusing and seemingly irrelevant topics. In short, I was unable to use this plugin to perform a spell check on my site.
