I had 40+ browser tabs open that I kept meaning to read. The problem wasn't saving articles — it was actually reading them. My Kindle is the only place I finish things, so I built WebToBook. Amazon's own Send to Kindle extension fails silently and has hundreds of 1-star reviews. WebToBook replaces it: open any article, click the extension, it's on your Kindle in seconds. No account dashboard, no subscription — just your email and Kindle address.
