CareerOS

Automatic study time tracker for interview prep. Counts only on the sites you choose: no URLs, no page content.

CareerOS measures the time you spend studying for technical interviews, automatically, on the sites you choose. Interview prep is spread across LeetCode, NeetCode, docs and videos. Timers get forgotten and screen-time apps mix study with everything else. CareerOS counts only what you call study. HOW IT WORKS • Pick your study sites (up to 12; subdomains included), for example leetcode.com or neetcode.io. • Study as usual. Time counts only while a study site is the active tab and you are at the keyboard. • Step away and it pauses after 60 seconds. A study tab playing sound (a video, not muted) keeps counting for up to 15 minutes without input. • Sessions are saved on your computer first and uploaded every few minutes; offline, they wait up to 30 days. • See your week on the web dashboard: time per day and per platform, across every computer you use. PRIVATE BY DESIGN • For your study it keeps only the site name, when you started and stopped, and a random ID for the computer. • It reads the active tab's address only to get the site name. It never stores or sends full addresses, page titles, page content or the sites you did not choose, and never tracks incognito windows. • No ads, nothing sold. The extension sends no analytics. Delete your account and your data anytime (see the privacy policy). Sign in on the dashboard with Google or GitHub, then connect the extension from there. Free, no paid plan.
