Find your next obsession.

You buy a membership plan rather than individual courses. The plan grants a number of course slots — three slots means three courses open at a time — plus an allowance of previews and a stated amount of video, voice and chat tutoring per period. You choose which courses occupy your slots, and you can move that capacity to different courses over time.

A slot is locked for the whole billing cycle, so nothing is taken away mid-period. At renewal you decide slot by slot which courses to keep and which to free. A freed course is parked, not deleted: your progress, test results and summaries stay saved, and you can bring it back into a slot in a later cycle.

It depends on the plan, and every plan says so on its card. Plans state how many video and voice sessions they include per period and how long each session runs, along with the size of the chat allowance. Where a plan sets no ceiling on a feature, the card says so directly. If you need more than your plan carries, add-ons and session packs extend it.

A preview opens a course's full first chapter without spending a slot, so you can read a real chapter before committing one of your places to it. Your plan grants a set number of previews, and they are a lifetime allowance rather than a monthly one — a preview is spent once on a course and is not returned.

An author uploads a book or a PDF and Cavua structures it: reading the document, designing the syllabus, writing the lessons, then finishing up. The result is chapters, lessons and tests drawn from the author's own material. The author edits and approves the course before publishing it, so nothing reaches you that the author has not signed off.

You can claim a certificate once you have completed a course and passed its final test, and your chapter and lesson test results are saved along the way. They are not accredited by any external body, and we will not pretend otherwise — what a Cavua certificate records is that you finished the material and passed the tests written for it.

Authors earn royalties on their published courses, plus referral income on two separate streams: authors they bring to the platform, and students they bring. Producing a course costs upload tokens, which an author buys — so the cost tracks what is actually published. An author subscription reduces the rate paid per upload.
