Four open-source tools for students preparing for exams, teachers building assessments, and anyone who believes learning software shouldn't come with a subscription.
Education has enough gatekeepers. These tools have none.
Liberated.Info is a collection of free, open-source educational software — built to be used, forked, modified, and shared. No subscriptions. No paywalls. No data collection. No accounts. Just tools that work.
These are built for students sitting high-stakes exams, teachers who need flexible tools in the classroom, and institutions that want capable software without vendor lock-in. Take them. Use them. Make them better.
