Quick,
Lightkey works completely offline.
All browser comments are strictly for GOTD registration.

Lightkey Dev,
Thanks, Installed successfully!
(much simpler and quicker than some confusing comments that scared me)

Chris,
To activate your license using the GOTD provided key:

Open Lightkey’s Control Center from its tray icon => Click on the 'License' tab at the bottom left corner => Click on 'Activate Lightkey' and select the 'lifetime option' => Enter the provided key to activate the license

Fadi, You're welcome to check our technical support guide: https://lightkey.blob.core.windows.net/documents/Lightkey.TechnicalSupport.pdf

Martin, unfortunately, Thunderbird is currently not supported.

Replying to myself. No, it does not. A really nice piece of software but this make it virtually useless for me.

Peter, The Same Exact Thing happened to me. But I saw a comment that said be sure to paste the www in the same browser that you downloaded the program with. I downloaded in my AVG Secure Browser, and then copy and pasted the URL into that browser and it worked so easy. PLEASE NOTE: When I added the Extension to my Chrome Browser, then copied the URL into that browser, it didn't work and showed the same Initial Screen (as you said) because it was a different browser. Use Same Browser for Downloading and for Getting Key. It is a Cookie Thing, I think. This Looks Promising!!

HMarx, thanks for bringing this to our attention.
Indeed, the lifetime license provided here today does not include future updates.

HMarx, i am a user. Lightkey Control Center/Dashboard > Preferences >License. There are 3 windows for choose. Choose the "lifetime" and click and to put into key. Do not put it into the last "website license" or any other. Right choose, pls. And everything will be OK.

Lightkey Dev,

It seems to be working well, as intended -- thanks yet again (and for your clarification reply).

However, I notice that even though "Exit" is chosen from the right-click menu of the Control Center's taskbar icon, only the Control Center app process/task itself stops. The "Lightkey Background Service" and "LightkeyNeuralService" continue to run (no doubt by intended design).

If possible, I think it would be nice to add a Preference option (or perhaps a "confirmation" on exiting) to totally exit all aspects of Lightkey upon "exiting" the Control Center; and/or also to have a choice to launch those background services upon Windows boot or to run only while the Control Center is also running.

Lightkey Dev, Thank you I've installed and registrated it into notebook. It doesn't want to install into desktop system, from unknown reason. I'll test it. Blessings and thank you for work.

Dale Royer, did you try to put both keys in two programs? Or try to use VPN for it, at least. I am a user, not admin. Try, if you'd like it.
I installed into notebook also. No problem was.
Kind regards,

senzai6293, License migration is possible, but indeed requires to first uninstall from the original machine before activating on the new machine.
You're welcome to follow the instructions in our dedicated guide:

Lightkey Dev, thank you very much.

Lightkey Dev, It tried to do that but It failed, It keeps prompted me conflict and mulitple activation, but i have completely uninstalled It from my previous device

Jan Aguilera, open the Control Center and then click on "License" in the bottom left, the rest is self-explanatory, just make sure you select "Lifetime" to activate.

Jan Aguilera,

BeGee, Thanks for sharing your feedback. 
Please see our answer below:
Installation location- indeed, this is not customizable by default, in order to allow the smoothest experience on as many configurations as possible and avoid potential permissions issues. That said, it's important to note that deploying deep technology that's comprised of several core Windows services as well as neural networks (that actually run locally on your machine!), has its system prerequisites and limitations (one of which being the installation location).

Bob McKelvy, well, that's exactly what I try. But the link in the readme.txt just redirects instantly to this page, the download page. This happens on three different computers, with 3-5 browsers each as well as with three different mobile devices.

Maybe there's a restriction for Germany. Might try it again with a proxy...

Andi05, no restriction for Germany nor any other locations... Please make you use the same browser for the archive request and registration page visit. Also, make sure your browser saves the cookies!
Esther added some useful tips here-below as well.

Eran B, the website is whitelisted, so all scripts, ads and cookies are allowed. But I got in running eventually. Funnily, by using a *different* browser and an online proxy, which redirected my request via the USA.

I still might uninstall this program again as I'm typing faster than the software could suggest the right words. It's doing latter pretty awesomely, tho. But hitting a key (like Tab) in order to fill in the whole word takes longer than typing it and it also stops the "flow" while typing.

Andreas Bischoff,
Thanks for sharing this feedback!
Please note that you can configure the prediction interactivity to best fit your typing speed, in which case you will only get more impactful / multi-word predictions (no matter how fast you type, getting 5 or even 10 (up to 12) words ahead using a single click is faster...). Depending on your typing patterns and how often you use repetitive sequences, it may take anytime between a few hours to a few days/weeks for Lightkey to learn it and suggest more meaningful predictions.

Andreas Bischoff, I saw a "wishful TAB" feature and which priorities are to be suggested - may be of help?

Pankaj Vijay, ther website says the plugin only works with Edge & Chrome.

Esther IT co, That's the problem! The link from the readme.txt redirects me instantly to this page. No matter which PC I use, which browser, even mobiles are getting redirected to here.

Andi05,
please read the official GOTD comment at the top of the page.
There are no restrictions for any countries and Esther is not working for the company or our site, she is the usual user.

GOTD team

Helen , YES! I am a simple user. Helen is right. I only wanted to help.

Andi05, after downloading pack put, pls, link from readme file in the same windows and you will get needed page. If you will put it into another browser window you will redirect on the front page. PUT IN THE SAME from which you've done downloading. What` s a problem? Download and put link in the same page.

Esther IT co, as stipulated in the product features here-above and in Lightkey's privacy policy on its website, none of the user content ever gets sent to any cloud.

Eran B, Thank, you for the explaining. Blessings.

Neil, No choice of which HD to install to, = Deal breaker for me

Neil,
+1
It's definitely a deal breaker. And, just for an add-on like this (automation of typing), 300+ MB of drive space, meh!!! Browser based Gmail or Outlook pretty much does automated typing nowadays. And, I use free WPS office, can't afford MS office (fairly heavy for my old lowly specced laptop, too). This program neither supports WPS nor is compatible with LibreOffice. I would say no to it.

Mukhi, Neil - thanks for sharing your feedback.
A few comments to clarify-

Installation location- indeed, this is not customizable by default, in order to allow the smoothest experience on as many configurations as possible and avoid potential permissions issues. That said, it's important to note that deploying deep technology that's comprised of several core Windows services as well as neural networks (that actually run locally on your machine!), has its system prerequisites and limitations (one of which being the installation location).

Resource consumption- considering the compute power necessary to deliver relevant predictions and spelling corrections in a variety of applications under 10ms, Lightkey's use of memory and/or CPU is extremely efficient and conservative.

Privacy - Lightkey is a local solution and thus your content never gets sent to any cloud (unlike many browser/cloud based tools that have complete visibility into anything you type). In addition, being local means it doesn't rely on internet connectivity (again, unlike browser-based tools that take perform their compute on the cloud).

Chuck, check your Windows 10 settings:
https://www.minitool.com/news/move-programs-to-another-drive.html

There you can read how to tune your Windows that all new software is stored on D. You can change this anytime you want.

Steven, would you, please, to describe more concretely in which features is it good? Thank you in advance.

h, Good day, You need to put link from which you've downloaded program pack in the same window and write needed information into the windows. You'll get the key.

2) Sorry, did not understand firstly. ^) Lightkey Control Center/Dashboard > Preferences >License. There are 3 small windows for choose. Choose the "lifetime" and click and to put into key. Do not put it into the last "website license" or any other. Right choose, pls. And everything will be OK.

Joe T, I am a user. Lightkey Control Center/Dashboard > Preferences >License. There are 3 windows for choose. Choose the "lifetime" and click and to put into key. Do not put it into the last "website license" or any other. Right choose, pls. And everything will be OK.

Congratulation! You rock.

Sam Richmond, Good day, You need to put link from which you've downloaded program pack in the same window and write needed information into the windows. You'll get the key.
