LockIn
A browser lockbox for focused, distraction-free studying
LockIn is a browser extension built for focused studying. Basic Mode blocks a large list of AI websites, while Exam Mode takes it further by blocking AI plus social media, entertainment, blogs, and other distractions. Password protection makes it harder to simply disable when you're tempted. You can also add your own websites to a custom blocklist.
Hey Product Hunt!
I built LockIn because I wanted a simple way to study without constantly falling back on AI or getting distracted by the internet.
The idea is pretty simple: sometimes you want to solve a problem yourself instead of immediately asking ChatGPT, Claude, Gemini, etc. LockIn lets you block those sites behind a password.
It also has an Exam Mode, which goes further and blocks AI + common distractions like YouTube, Instagram, Reddit, blogs, and other sites that can pull you away from studying.
There's also a custom blocklist, so you can add any website you personally want to stay away from.
I'd really love feedback from the Product Hunt community — especially on the UX, features, and anything you think I should improve.
Thanks for checking it out!
