Get Scolded for Opening Too Many Tabs!? Enjoy Organizing Tabs with Tab no Kimochi

For those who have so many tabs that they no longer know what's what.

Tab no Kimochi is a fun and unique Chrome extension that indicates tab status using cute character "mood icons". Small changes in expression displayed at the top-right of the screen let you see how crowded your tabs are at a glance.

Quick Overview of Key Features

  • Icon changes based on tab count Expressions change in three stages: 'few', 'normal', and 'many'.
  • Eight characters available in total (paid version) The free version includes two live-action characters (male and female). The paid, one-time purchase (¥690) unlocks characters such as a tsundere girl, a soothing type, a cat, a handsome guy, and more.
  • Choose from five modes Tab count thresholds include "Minimalist", "Relaxed", "Standard", "Power User", and "Limit Break", allowing you to match your preference and use case.
  • Blinking speed is also customizable (paid setting) Adjustable to slow (0.8s), standard (0.5s), fast (0.3s), etc.
  • Privacy-first, secure design It only detects tab count and does not handle history, personal information, or transmit data externally.

🛠 Admin's Hands-on Impressions

This extension was developed by a Japanese developer. Out of curiosity, I opened many tabs to see it scold me!

It was a bit disappointing that the free version only allows two selectable characters, but even the default older-man character will scold you!

Installation and Usage Steps

  1. In Chrome, go to the Chrome Web Store page for Tab no Kimochi (chromewebstore.google.com)
  2. Click "Add to Chrome" → install the extension
  3. Click the icon that appears in the toolbar to pin and enable it
  4. Select a free character and check your tab status by its expression
  5. If you want finer settings or additional characters, upgrade to the paid version (¥690)
  6. In the settings screen, adjust the blinking speed and threshold mode to your preference

Privacy and Functionality You Can Rely On in Tab no Kimochi

  • Completely offline design: detects only tab count and does not handle history or personal information
  • One-time purchase paid version (¥690): once purchased, you can use it indefinitely

Summary

Tab no Kimochi offers more than mere efficiency for those troubled by too many open tabs — it provides a slightly enjoyable experience. A single expression helps make tab organization more fun, and it's an excellent extension that emphasizes customization and privacy. Try the free version first to find your own tab management style!
