Raindrop.io is the best place to keep all your favorite books, songs, articles or whatever else you come across while browsing.

We're not trying to reinvent the wheel; we're working on a tool that does everything you expect from a modern bookmark manager.

Collections of links. Folksonomy tags. Filters. Finds duplicates and broken links for you. Full text search. Automatically makes copies of every page you bookmark to prevent link rot.

Unlimited bookmarks, collections, and devices indefinitely at the free level. Additional features (probably collaboration) at paid tiers.

Online service that does text-to-speech as a service. Free at the low end, cheap at the high end. If you can send it text (even an RSS feed!) it will read and turn it into recorded audio with a synthesizer. Supports 26 languages.
