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!
