What Sophia does, and what it costs. Anything not covered here: hello@bytexy.com.

How does Sophia build a course?

Give Sophia a topic or your own material. It can read the sources you provide, research the open web, structure the subject, write the lessons, and draw useful diagrams.

Sophia designs the curriculum first. It works backwards from what you should understand by the end and builds a path there: fundamentals before advanced material, the shape of the whole before its parts, intuition before formalism. Use Preview to review this outline before starting generation.

Then it writes the lessons against that plan, reading your sources in full and pulling live web search and page fetch as it goes. You get a course that covers the subject and still reads as one course, each lesson landing where it belongs.

Is the content accurate?

Sophia grounds every lesson in material it can read: your sources, plus live web search and page fetch while it writes. A course reflects what’s findable today, not whatever the model absorbed in training. When a lesson leans on a video it links back to that timestamp. When it can’t ground a claim, it drops the claim, and a lesson with no usable material behind it fails the course instead of inventing one.

It is still AI and it can still be wrong: a misread figure, a confident sentence about something it half-knows. None of it is professional advice, legal, medical or financial. Check anything you plan to act on against the primary source. And when accuracy on a particular body of material matters, hand Sophia that material. A course built on your own sources beats one built on a topic name.

What can I build a course from?

A topic is enough on its own. “Teach me everything about Formula 1 aerodynamics” is a complete request. Sources are optional, and they pin a course to something specific: a link, a PDF, a video, an image, or a mix of them. Give Sophia a paper and you get a course about that paper, not about the surrounding field.

Can I use Sophia from Claude, Cursor, or another AI assistant?

Yes, through MCP: connect Sophia to your assistant and it can plan and queue courses from a conversation, signed in with the same Apple or Google account you use in the app. The setup guide covers Claude, Claude Code, Cursor, VS Code, Codex, Gemini CLI, ChatGPT, and Windsurf.

How long does a course take to build?

Usually a few minutes, and you don’t have to wait on it. Keep using the app or close it, and you can have several courses building at once. A big course built on something heavy, like a two-hour video, takes longer.

Are my courses private?

Yes. The topics, prompts, sources, and courses you build are not visible to other users. You cannot publish or share them through Explore. The Privacy Policy explains which providers process that material while building your course.

Explore is a separate, read-only catalogue of courses curated and published by Sophia. Saving one creates an independent frozen copy in your private library. If Sophia later takes the catalogue course down, your saved copy stays in your library.

Delete a course you built and it’s gone: the lessons, the sources you gave it, the images generated for it, its chat history, and the search index built from it. We delete the stored files themselves, not just the records pointing at them. We keep purchase and subscription records where legally required. We also retain limited credit, usage, generation-report, and anti-abuse records for refunds, support, cost auditing, and fraud prevention. Removing a saved Explore copy from your Library deletes your copy, not Sophia’s catalogue course.

The Privacy Policy covers what we collect, who processes it, and what deleting your whole account removes.

How are credits calculated?

Sophia runs on credits, and only two things spend them: planning a course outline and generating the course itself. Saving a course from Explore spends none.

  • Planning a course outline costs 15 credits, with or without Preview. The outline includes the course title, sections, and planned lessons. Choose Preview if you want to review the outline and generation total before starting generation.
  • Generating the course starts at 10 credits per planned lesson. A 20-lesson course costs 200 credits before any source charges.
  • Courses built on large sources cost more. Sophia carries a long video or a big PDF into every lesson rather than skimming it once, which keeps the material grounded and costs more per lesson. A video also adds a one-time fee for reading it through. You pay that fee once per course, ever, however much work the course needs later. Links to web pages add nothing.

Add course can start generation automatically after planning. It starts only if your credits cover the full quote and you have no outstanding debt. Otherwise, the course waits in Library until you add enough credits and press Generate.

You won’t be charged more than 10 credits per lesson plus any source charge for that course. We cover provider retries, generated images, and repair work within that price. Running out of credits cannot stop generation once it starts, but provider or system failures can still prevent delivery.

Where do credits come from?

  • A one-time free grant when you create an account, so you can build something real before paying anything.
  • A monthly plan. Basic, Plus, Pro, and Max each grant a set number of credits on every successful billing cycle. The App Store or Google Play shows and charges the price in your local currency.
  • Top-up packs, if you run out mid-month. A top-up requires an active paid plan and must match your current tier; it adds credits without changing or extending your subscription.

Credits are for use inside Sophia. They have no cash value, and you can’t redeem them for money or transfer them between accounts.

Do credits expire?

Credits granted by a subscription expire at the end of the following monthly billing period, so you have the current cycle plus the next one to use them. The app’s Usage screen shows the exact amounts and dates.

Free-grant credits and top-up packs never expire, including after you cancel or downgrade.

What happens if a course fails to generate?

A course becomes readable only once every planned lesson has generated. If a provider, safety, or system problem stops it partway:

  • We release any credits that were reserved but not used.
  • Credits already consumed by lessons that did succeed stay charged, pending support review.
  • You can report the generation from the app, with or without asking for a refund, and we’ll look at it.

A delivered preview stays charged even if you discard the draft, since the curriculum work was already done. The same goes for a preview you cancel or change after it starts reading a video.

Can I get credits back?

If a generated course is bad or broken, submit a refund request from the app. A human reads every request, so your balance and your access don’t change straight away. On approval we restore the credits that course consumed and revoke your access to it. Refunded credits expire two calendar months after approval.

Store-level refunds are separate. If Apple or Google reverses a purchase we remove the value it granted, and if you’d already spent those credits you’re left owing the balance, which blocks new generation until you clear it. When the refunded purchase is a subscription, any top-up credits you still have go towards that balance first.

How do I cancel my subscription?

Through your Apple or Google account settings, the same place you manage your other subscriptions. We can’t cancel it for you. Cancelling stops future renewals; it doesn’t change the expiry of credits you already hold, and courses you generated stay readable.

Deleting your Sophia account does not cancel a store subscription. Cancel it in the store as well.
