Designed by and for non-native English speakers. Reasonable for non-professional, innocuous use.

Despite the developers claim on their About Us web page that "We are a University of Cambridge spin-out", this application was clearly created by non-native English speakers for non-native English speakers. The company is based out of Zhejiang, China. (If you run a WHOIS check on their website, youre likely to come up with nothing using their DNS address. Instead use their source IP address, which is 42.121.128.165).

Since this is a web service run through an application, its important to keep in mind that text you submit into the application is passing through the Internet In-The-Clear (no encryption) and that it is specifically being sent to China. As such, I cannot recommend using their service for anything but innocuous text. By no means ever use the service for professional, important, private, copyrighted or patent applicable text. This is critical! Hopefully I dont have to explain why.

The quality of results from the service are NOT of professional quality. They are far better than many grammar checkers Ive used! Thats commendable. They are far better than average ChingLish text! Thats commendable. As such, this can be a very useful service, depending upon your expectations. But again, do NOT expect professional quality results. I provide some examples below, taken from their About Us web page. My comments are provided in brackets:

- "We are a University of Cambridge spin-out, specializing in Artificial Intelligence and Natural Language Processing (NLP) technologies. [Remove the comma.]
- "We are not a big team, at least not yet, but we want to deliver automated proofreading service differently:" [The correct word would be services, not service. The sentence is also incoherent with no connecting cause and effect.]
- "Frankly speaking, no grammar checker on the market previously is worth your money." [This sentence has bad syntax. Here is less confusing syntax: "no grammar checker previously on the market is worth your money"]
- "It is beyond our imagination that some grammar checkers only update once or twice a year." [This sentence approaches incoherence. Replace that with why.]

Summary: If the developers cant use their 1Checker service to provide them with perfect grammar, you cant either. The service is better than nothing and is much better than many other grammar checkers I have used. Remember to never use this service for professional purposes or for words you wish to keep private, confidential or proprietary. Promise me!
