Close 40 tabs today. Reopen them tomorrow in one click.

Chrome firstmacOS + Windows

You don't lose time. You lose context.

You close 40 tabs.

You switch projects.

You return tomorrow and can't remember what mattered.

Browser history isn't context.

Chrona is.

How it works

Three steps to flow

01

Capture

Chrona records tab and navigation events locally on your device.

02

Organize

Sessions are grouped into intent threads automatically.

03

Resume

One click reopens the exact tabs so you can continue instantly.

Perfect for research rabbit holes, multi-project work, and "too many tabs" days.
