Grammarly1.5.69

It's great until you find out that everything you type has been sent to their server for review for your purposes as well as theirs, so now you have no privacy and they have as much information as they want on you.

If only there was a real, seriously competent grammar checker available for Mac. IMHO there isn't. To have Grammarly among the (IMHO) incompetents, bombarding the Internet with ads for its software as well as charging (IMHO) exorbitant subscription fees is (IMHO) very upsetting. And supposedly we've entered the era of 'artificial intelligence'. Nope! Not in the field of grammar checking! Is English really so chaotic that no one can create a decent grammar checking program? *annoyed*

It has been updated

I was considering the upgrade to premium because I've been writing a lot more, but I write in Google Docs and it is not functional. Does anybody know of a way around that or if Grammarly is planning on adding this soon?

Grammarly would become a 'must have' IF: 1) the price would be fair (say 10 times lower) 2) it would work on Mail, Skype and any other program which uses text, not just text editors 3) if the suggested corrections would be less stubbornly presumptuouse, near imposing to lower the language AND PUNCTUATION level to a cheap one, good just for the crowd!

I have Mac OS 10.5.8 and need a program but can't find compatible one.

I suggest you beware this product. Not only the Company activates automatic renewals without consulting the user and without reminding that the expiration date is getting close, but the service rendered is fairly modest and is not worth the yearly 139.95 USD that they will surreptitiously charge you. Those charging policies are discouraged in the EU, but it appears that you may adopt predatory behaviours towards users in the US.
Also, there is no trace of actual development in Grammarly. Contrarily to Windows, there is no way to make it work on any word processor for the Mac although the release of a plug-in for Word has been promised for a long time now. I believe it is fair to claim that Grammarly is merely a beautifully marketed package that overcharges you for a service with little R&D.

It may be useful to know that while they automatically charge you full price, they litter your inbox with offer discounts.

The free version is more of a trial version that performs 150 checks. For a full featured product, with significantly more capability, the price of the subscription can range from $140-$360 a year, depending on the plan length.
