About this extension

Kiku Hours is a comprehensible input tracker. It counts the hours you spend listening to the language you're learning, accurately, so you always know where you are on the road to fluency.

Other trackers count minutes watched. That includes ads, pauses and videos in your own language. Kiku Hours works out the language of every video by listening and counts only the ones you're learning.

How it works

Say which languages you already speak. Everything else counts.
Watch as normal on YouTube, Twitch, Netflix and the other supported video sites.
Kiku Hours listens to the audio, identifies the language of each video and counts the time you listened.

What counts

Time is measured from the video player, so ads, pauses and skipping don't count. A tab in the background still does.
Videos in a language you already speak are recorded, but left out of your total.
If a video's language can't be identified, its time isn't counted. Nothing is guessed.

What you see

Today: your hours so far, your daily goal, your streak, and every video you listened to.
Progress: all-time hours, a chart of the year, a calendar of every day, and achievements.
Your data: everything stays in your browser. Export a spreadsheet, back up to a file, or restore on another computer.

Free, with no account and no subscription. 106 languages, from Japanese and Spanish to Arabic and Thai. The full list: https://kikuhours.com/languages

Works in Google Chrome, Brave, Edge and other Chromium browsers on a computer.

Audio is analysed on your computer to identify the language and then discarded. Nothing is recorded, stored or sent anywhere. Privacy policy: https://kikuhours.com/privacy

Coming next: more streaming services, and a way to correct a label by hand.
