A Note on Pricing & Future Plans
Currently, JustInfer is entirely free, offering everyone the opportunity to learn, practice, and teach formal logic without any charge, ads, or selling of personal data.
However, data storage and server costs make it infeasible to maintain completely free access to all of the site's capabilities.
The current plan is that future users would need to pay a one-time fee of approximately $10 to access course related features.
This would not affect users who have already created an account and enrolled in or created at least one course before this plan launches. You'll continue to enjoy free access to all course-related features indefinitely, including the ability to make and enroll in additional courses.
Moreover, all other parts of JustInfer, including logic textbooks, tutorials, practice problems, and custom settings, will remain permanently free for everyone! I am committed to keeping this an ad-free, privacy-respecting, and affordable platform for learning and teaching formal logic.
If you'd like to help me continue offering course capabilities for free, please consider supporting JustInfer through a donation.
Thank you for your understanding and for supporting JustInfer!
