Summary
Daniel Nguyen founded KTool, a tool allowing Kindle users to send news articles, newsletters, and RSS feeds to their Kindle, bundling content into a daily magazine format. KTool was developed to reduce screen time and provide a convenient reading experience on Kindle. The idea originated from Nguyen's personal concern for his eye health and the limitations he encountered with existing Kindle-related products. KTool achieved $1K in monthly recurring revenue (MRR) and was initially promoted through building in public on Twitter.

Unique Aspect
KTool's unique feature is its ability to bundle various online contents into a single daily magazine format specifically for Kindle, addressing a niche market.

Approach to kick off
Nguyen validated his idea on Reddit, then shifted from a macOS app to a browser extension focusing on sending articles and Twitter threads to Kindle, gaining better traction.
