"Significant productivity boost"
What do you like best about Lightkey?

I’ve been using Light key for almost two years now and I can’t imagine writing without it. I feel like Lightkey already knows me so well that it literally completes all my sentences.

What do you dislike about Lightkey?

No downsides that I can think of. It’s very unobtrusive and you don’t have to accept the predictions, but very quickly you’ll find that you will.

What problems is Lightkey solving and how is that benefiting you?

Productivity and speed in writing.

"A second nature productivity tool"
What do you like best about Lightkey?

I find Lightkey is super smart and adapting.

What do you dislike about Lightkey?

Nothing comes to mind. I know it's not compatible with Mac.

What problems is Lightkey solving and how is that benefiting you?

Lightkey quickly adapts to my style and the content I'm working on. I get much more writing done in short periods of time. For some of my more repetitive emails or documents, I hardly type anything at all.

"Perfect tool for creative thinkers"
What do you like best about Lightkey?

Best of all, you can use it without having to open a separate piece of software. The app works flawlessly with Microsoft Office and Google Chrome, and you can trigger the Lightkey Anywhere function to have it humming along in any application. Compatible with more than 80 languages, the program is also available offline—removing any concern your work will be uploaded to the cloud.

What do you dislike about Lightkey?

pricing is a little steep i dont think i'd want to pay 30-50 dollars for a text editor where there is alot of sublime text with dev packages achieving the same thing

What problems is Lightkey solving and how is that benefiting you?

Used it and gave it a try when finalizing one of my projects internally and tried it out. It is a good tool to play around with but totally upto the user what they find fit.

It also corrects grammatical errors and suggests interesting words. Also, often you don't need to enter full text; just by pressing 'enter' the whole word is written automatically

What do you dislike about Lightkey?

None so far. Every feature has been very useful to me.

What problems is Lightkey solving and how is that benefiting you?

Helps me make less mistakes, and write faster

"Lightkey sets a new standard when writing articles, book summaries and E-mails."
What do you like best about Lightkey?

As someone who spend a lot of time typing out extensive summaries of educative books, writing articles and too many E-mails (as of late), Lightkey.io is a blessing since I discovered and implemented it about two years ago. Since Lightkey keeps track of how much time you have saved literally, by using the suggested words and combination of words, it is astonishing to see the saved up time after a few months. It takes a short bit of time to use Lightkey to its full potential due to my old typing habits, but I have come to the point that I feel I waste precious time typing E-mails and notes on other devices without Lightkey installed. I am always looking for ways to improve my knowledge, my efficiency, my routines. I am always looking for ways to automate tasks work- and not-work-related. With the features Lightkey offers, Lightkey has become an essential cogwheel in my system.

What do you dislike about Lightkey?

There is not much to dislike, but if I have one suggestion for improvement it is this: As someone with the luxury of an extensive set-up of devices (3 Desktop PC's, 1 Laptop, 1 Surface Pro Tablet and 2 Smart Phones) I really wish there is a more friendly subscription option for one sole user available. To make use of Lightkey on more than one device you are required to buy additional licenses for each device on which you want to make use of Lightkey. I understand the business model completely. Although I can only be active on one (or two including my phone) devices at a time. Personally I do not want to purchase more than two licenses because of that. Especially when it is for devices I make use of only a few days a year effectively and incidently. There are different other-related software products (e.g., Evernote, Netflix) out there with a subscription plan which gives the consumer the option to make use of a product on additional devices with 1 license, 1 subscription fee. That said, Lightkey offers really affordable lifetime subscription plans. And 1-year subscription plans with discounts for more multiple (2-10) devices.

What problems is Lightkey solving and how is that benefiting you?

I decreased the time between words forming in my head and generating the words as output on screen! Repetitive lines and words are suggested c.q. auto-completed with just a keystroke (TAB), resulting in a significant increase in productivity and output. I make less mistakes with the spelling of complex business-related research terms since Lightkey auto-completes what I am aiming for.
