Yes, you can evaluate both Cloud and Server versions of the WebSpellChecker products for free within 30 days.
There are three types of products available:
As soon as you defined which type of the product you need, you can subscribe to 30-day trial version from our website accordingly.
The base annual price for the Cloud service is $150. It covers the service usage up to 20 million words per year. The services calculate the total number of words, which were processed, no matter their correctness level.
However, there is one thing that you should keep in mind. There is a mechanism of “caching/remembering” previously checked words during this active session (until the page reload). Thus, the products remember already checked words and won’t send them again for spell checking.
For example, if you have text something like “Hello, how are you” and the user adds at the end of the sentence a word “today”, so a new sentence is “Hello, how are you today”, then the only one word “today” will be sent to the server for checking. After that, the user adds “. Hello” and pauses for a few seconds, so a new sentence is “Hello, how are you today. Hello”. In this case, no requests will be sent as all these words have been already checked as we know that “Hello” is a correct word.
You can check your usage statistic for the previous month and since the previous payment date from your subscription management panel on our website. When you sign up for Cloud services you receive “WebSpellChecker subscription” email. There you can find your initial credentials to login.
If you end up exceeding the limit, the service will stop working. However, our team monitors the usage, and notify customers beforehand with the proposal to purchase another set of words. In this case, the price depends on the potential customer usage (per year) and the price of the appropriate usage plan.
Please see the complete Terms of Service for the Cloud services.
