Lightkey Reviews in June 2025: User Ratings, Pros & Cons

"A very happy user"

What do you like best about Lightkey? Obviously it's great for improving the spelling in my documents, but what I really love is the facility to predict my most commonly used text, such as email opening sentences. I'm not a great typist (or speller) and it saves me work, and minimises my mistakes.

"Lightkey sets a new standard when writing articles, book summaries and E-mails."

What do you like best about Lightkey?
