Cerno
Sign in— A second brain that reads
Save anything.
Revisit everything.
Cerno reads what you save, files it into your library, and surfaces it back to you when it matters. Articles, tweets, videos, places — extracted, summarized, searchable, and yours.
— How it works
01
Save
Paste a URL, share from any app, drop a screenshot. Cerno fetches the page, extracts the article, transcribes the video, captures the tweet — and stores the raw text so you can read it later in your own library.
02
File
Every save gets sorted onto a shelf by your AI — Build, Queue, Life, Body, Style, TV/Movie, Location/Event. You set the shelves. Cerno learns your taxonomy and uses it consistently.
03
Ask
Chat with everything you've saved. Cerno cites titles, remembers what you've told it about yourself, and pings you proactively when something on your library needs attention — an event next week, an article you forgot to read.
— Not a bookmark tool
The web you saved, made readable.
Bookmarks die. Articles get paywalled, tweets disappear, blog posts go offline. Cerno saves the actual content — the article body, the video transcript, the tweet thread — at save time. Years from now it's still there.
— Yours, end to end
Private by default.
Your saves are private and accessible only to you. No ads, no algorithmic feed, no engagement metrics. Cerno is a personal library, not a social product. Export everything anytime; delete your account in one click.
