Best conversion quality
I believe that simplicity should not come at the expense of quality. KTool turns web articles into high quality e-books.
I love the quality of KTool article conversion, much better that what I had built, which was better than other solutions!

@daniel\_nguyenx This is dope

Just thought of using my Kindle again before going to sleep today and tried KTool of @daniel\_nguyenx, it’s awesome and makes a lot sense now! 🤩 Now I want to send many things to my Kindle to read before going to sleep, without being hooked to the platforms 🪄👌
Alex@AlexCharlesGoff[](https://twitter.com/AlexCharlesGoff/status/1509280263955755017)
I have a constant list of things I should read, while also a Kindle with nothing in it. @daniel\_nguyenx built a easy way to ping things to it in a second. It's flipping great.

1 year ago I gave away my Kindle because ktool.io by @daniel\_nguyenx didn't exist. Today I'm looking into buying a new one.
Louie Bacaj@LBacaj[](https://twitter.com/LBacaj/status/1545785398466695168)
I finally got a kindle and it’s pretty cool. But the best part, by far, is to be able to read my newsletter and some of my other favorite newsletters on it. @ktool\_io pulls everything in surprisingly cleanly too, just text and images none of the web junk.
Samuel Nygren@nygrensamuel[](https://twitter.com/nygrensamuel/status/1554447422193078272)
Innovative tool of the week #2 @ktool\_io, a tool that let you send web articles, blog posts, Twitter threads and newsletters to Kindle in a good looking way 👌🏽
Dave@dasalter[](https://twitter.com/dasalter/status/1528339228832169990)
Just purchased a lifetime license for @ktool\_io to send longform articles to my Kindle app on my Boyue Likebook eReader. It's the best 'To Kindle' conversion I have come across so far. Looking forward to seeing this app progress.
Dominik Sumer ✨@dominiksumer[](https://twitter.com/dominiksumer/status/1509520137149456398)
finally had the time to give @ktool\_io a try .. @daniel\_nguyenx is creating a stellar product there! if you have a Kindle this is a no-brainer - read any website (e.g. blog posts) on your Kindle! I'd highly recommend to grab yourself a lifetime deal as long as it's available 🔥
Dan Rowden ⚡️@dr[](https://twitter.com/dr/status/1498348987161751554)
@daniel\_nguyenx @ktool\_io Looks awesome. I had two long blog posts in tabs today that I closed because I just wasn’t going to read them on my computer. Sending them to my Kindle would have been awesome
Ayush@Ayushpokh[](https://twitter.com/Ayushpokh/status/1503462769491947524)
shoutout to @daniel\_nguyenx and his product @ktool\_io . I've been trying to read more on my kindle (off social media) and his tool makes it super easy to send articles and links directly to my kindle (reader formatted too!) It's really amazing how easy it is.
Jamie Madden@dcwhatwhat[](https://twitter.com/dcwhatwhat/status/1504025612347842561)
Finally got around to signing up for @ktool\_io guess who’s sending long form web articles to his kindle from now on? This guy.
Tom Fallowfield 💡@tomfallowfield[](https://twitter.com/tomfallowfield/status/1527257051986010112)
Just used the free tier of @ktool\_io to send a "long read" article to my Kindle and the entire process was streamlined and beautiful. Absolutely love it. Great work @daniel\_nguyenx!

@daniel\_nguyenx @ktool\_io now that's a cool project idea. kindle always feels very relaxing to read.
Who am I?
I'm Daniel Nguyen. In June, I quit my consulting job to start indie hacking on the side.
The idea of KTool first came to my mind when I was reading Ask HN: I'm a software engineer going blind, how should I prepare?
I've been wearing glasses since I was 5. My right eye is basically blind. Doctors said there is no chance to cure it.
I was genuinely scared. Like holy sh\*t, if my left eye stops working, my life is done. Since then I've been very conscious about time spent on computer screens.
That's when I started using Kindle-related products: to offload as many reading materials as possible to the Kindle.
Then I ran into multiple limitations which led me to build KTool: a tool to send anything online to Kindle. Blog posts, Twitter threads, Hacker News discussions, RSS, newsletters, your favorite manga... you name it.
If you're a Kindle owner and read a lot of online content, give KTool a try.
