✦ Your external memory for the internet
How many tabs are you keeping open just because you're afraid to lose them?
Pinity preserves everything important you discover online, so you can access it later from any browser, any device, anywhere.
The Hidden Cost of Open Tabs
Tabs are not open by accident.
There is a real phenomenon called Tab Hoarding: people keep hundreds of tabs open because each one represents something they don't want to lose.
One Firefox user kept more than 7,500 tabs open for over two years. Not because she needed them today. Because she was afraid of losing them tomorrow.
A tab stays open because there was a reason to open it, and you're not ready to lose it yet.
Over time, your browser becomes a storage system for ideas, research, projects, and knowledge it was never designed to hold.
The real problem
Every open tab is something you're afraid to forget.
And that fear is exactly what keeps your browser overloaded. Eventually your browser stops being a tool and becomes a fragile memory system. Because...
Browser crashed
One unexpected crash can wipe out hours of open research.
Closed the wrong tab
That one valuable page disappears right when you need it.
New computer
Switching devices often means losing your browsing context.
Changed devices
What you found on one device is hard to recover on another.
Cleaned history
Browser history is messy, temporary, and difficult to trust.
Too many tabs
You keep everything open because you're afraid to lose it.
Every open tab becomes an unplanned backup for ideas, research, and knowledge.
Why Pinity exists
Once upon a time, a browser with 317 open tabs...
Pinity started with a simple frustration.
Our CTO had hundreds of tabs open across multiple devices.
Not because he needed them today.
He kept them open because he was afraid of losing something important tomorrow.
Then one day, a crash happened.
Years of carefully preserved information disappeared.
That's when we realized the problem wasn't the browser. The problem was using tabs as a memory system.
For the first time,information could survive
without keeping the tab alive.
