Learn a little. Try it yourself.
Work through an explanation, put it into practice, and return when you’re ready for more.
Practice is part of the lesson.
Read an explanation, follow an example, and make your own attempt. Use feedback to see what needs another try.
Read the teaching standard- Work you can revisit
- Your notes, practice, and progress stay in your account.
- Sources you can inspect
- Lessons distinguish source-backed material from AI general knowledge. A reference alone does not verify a claim.
- Progress that stays honest
- Finished work, graded work, and attempts you haven't reviewed are shown separately — your progress is never inflated.
Before you sign up.
What you can see, what an account changes, and how AI is used.
Can I inspect a course before creating an account?
Yes. Published outcomes, modules, lesson titles, prerequisites, time estimates, and assessment structure remain public. An account is required to open lesson bodies and save work.
What does a free learner account include?
A free account opens every published lesson and saves your progress, notes, practice, and review schedule across devices.
How does Filosage use AI?
AI helps draft explanations, examples, practice, tutoring, and courses. New courses are checked for structure, safety, language, and teaching quality. Course pages distinguish verified sources, AI general knowledge, and further reading.
Are paid memberships open?
Not yet — paid plans are in final testing. Leave your email on the pricing page and we'll tell you when they open.
