Pin takes directly onto the page.
No free lurking—real discourse requires real skin in the game. Pin your thoughts to any sentence, image, or video across the internet. Cheaper than bad coffee, kills 100% of bots.
Why It Is So Hard to Concentrate Anymore
How Pinuu works
A lightweight extension that turns the entire internet into a shared pinboard.
Highlight anything to comment
Select a sentence, click an image, or pause a video. A clean popup lets you write your note directly on the page in two clicks.
See notes from people you follow
As you browse articles, recipes, or documentation, little pins appear in the margin showing notes from writers, curators, and friends you follow.
Save private notes for yourself
Need notes just for your own research? Flip the toggle to private to build your own personal notebook across every website, accessible anytime from your browser sidebar.
Why is Pinuu $2.99 a month?
Free social platforms are overrun by fake accounts, spam bots, and rage-bait because creating an account costs nothing.
At $2.99 a month (or $30/yr), running a 10,000-bot spam farm costs $29,900 every month. That simple price filter keeps Pinuu 100% human. Cheaper than bad coffee, kills 100% of bots. And because members pay for the service, we never show ads or sell your browsing data.
