Biology
Chain Reaction
A cause-and-effect chain builds itself, then lets you trace it.
From the example lesson How vaccines train the immune system
Sample

- A lesson takes minutes to build, not seconds.
- English first. Other languages work but get less testing.
Questions
How is this different from asking a chatbot?
A chat answers one question at a time. Philocoursa plans a whole course first, then writes every lesson with slides, a handout and a quiz, in order, so you can study it through or teach from it.
Is the content accurate?
AI can be wrong. You review the plan before any lesson is built, every lesson shows its sources where it has them, and every download is an editable file, so you can correct anything before you use it.
How long does a lesson take to build?
A few minutes. You can leave the page while it builds.
Which subjects work?
Anything you can describe in a line or hand over as a syllabus. The example lessons are finance, biology and physics.
What can I download?
The handout as Word, the slides as PowerPoint, the quiz as PDF.
What does a credit buy?
A course plan costs 150 credits and covers up to 5 modules and 20 lessons. Each lesson's content costs 40; its handout 60, slides 25 and quiz 50 (up to 30 questions). A complete lesson is 175. Checking an attempt that needs AI grading costs 50. You get 400 free credits once, after you verify your email, while free places last. Credits never expire.
What happens when my credits run out?
Release 1 runs on free credits, and everything you build stays yours to open and download. Subscriptions, the better-value way to get credits, and one-off top-ups arrive once payments open. No card is needed until then.
Who can see my courses?
Only you. Nothing you make is public unless you share a download. The service providers we use to run Philocoursa, such as our AI provider and hosting, process it only for that purpose.
