I built Folio because I kept getting distracted by notifications when trying to read on my phone. Folio takes your open tabs, RSS feeds, and newsletters, and turns them into a cleanly typeset digest. You get a private email address for newsletters, and it strips out the ads and menus. Then it automatically delivers a custom PDF or EPUB directly to your reMarkable, Kindle, or Google Drive. The idea is to move your reading to an e-ink device, so you can actually focus.

Every memorial gets a shareable page, visitor roses, permanent plot adornments, and a weekly honors leaderboard. It turns the useful truth at the end of a project into closure, a launch asset, and a path to the founder’s next chapter. $12 per obituary; no account needed to browse.

An animated pixel-art map of the solar system with every body at its real current position, computed from published orbital elements rather than copied from a list.
