Who am I?
I'm Daniel Nguyen. In June, I quit my job to start indie hacking full-time.
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.
That's me and my daughter, trying to build a profitable Internet business
