Spaces

Your tabs, organized into Spaces

Pin the tabs you keep, file them in folders, and switch Spaces with a click.

Spotlight

Find anything. Run any command.

Search your tabs, pins and Spaces, or run a command, right from the keyboard.

Spotlight open over the browser window with “copy” typed. The results are the commands Copy URL and Copy URL as Markdown Link, an open tab whose title matches, and a web search.

Split view

Split view, pinned for later

Keep two pages side by side, and reopen the pair from a single pin.

Themes

Colors and themes for every Space

Give each Space its own colors, a gradient, and a light or dark look.

The theme editor open in the side panel of the Personal Space, which is tinted coral and pink. It has a color field, a row of preset colors and a light, dark or auto switch. A travel article is open beside it.

And more

The small things that keep a sidebar out of your way.

  • Live folders

    A folder that lists your Gmail inbox or a label, or your GitHub review requests, pull requests, issues and mentions, using the accounts you’re already signed in to.

  • Archive

    Temporary tabs you haven’t used for a while are closed and kept in the archive, ready to bring back.

  • Keyboard shortcuts

    Open the side panel or Spotlight, and copy the current URL or a Markdown link. Choose your own keys in Chrome’s shortcut settings.

  • Export and import

    Export everything to a file, and import it again whenever you need to.

  • Four languages

    English, Japanese, Simplified Chinese and Spanish.

  • The file is read inside your browser and never sent anywhere.

Privacy

Nothing leaves your browser

Katip has no server and collects nothing. Your Spaces, pins and settings live in Chrome’s own storage and bookmarks.

  • No server, no account

    There’s nothing to sign up for. Katip sends nothing to its developer or to anyone else.

  • No tracking

    No analytics, telemetry or ads, and no code loaded from the internet.

  • Live folders, when you allow them

    Live folders talk to Gmail and GitHub directly from your browser, with the sign-in you already have, and only after you allow access to that site.
