Age-appropriate content and safety

Epivo's curriculum is authored by AI against a fixed structure: a course, its learning goals, and the specific topics inside each one. It is written and stored before any student sees it. The curriculum is fixed; the tutor's actual words are generated live in each conversation.

Before written lesson material can reach a student it has to pass:

• A fact-check in which an AI checks its key facts against independent published sources, and a second AI independently re-checks anything flagged as wrong. Errors are corrected or the material is removed; anything the two disagree about is withheld from students and not taught — it is not shown with a caveat.
• Mechanical checks on how it reads aloud: sentence length, explanation length, and no on-screen formatting.

What we do not do is have human teachers write or sign off on every piece of content, and we would rather tell you that than imply otherwise. The fact-check covers whether something is factually sound. It does not assess whether a topic suits a particular age.

History includes war, persecution and atrocity, and we teach it rather than skirting it. Film that is distressing but not graphic is for 13 and over. Film showing bodies, or people in severe distress, is for 16 and over.

Those two ages are our own judgement. No ratings board or curriculum sets them. If we do not know how old a learner is, they see only the gentlest level — not knowing always means seeing less, never more.

These limits apply to film. Still images are not individually age-rated, and we are not going to claim they are.

The tutor is told the learner's age and is instructed to keep its vocabulary and explanations suited to it. That is guidance to the tutor, not a filter on the material.

Grade level shapes which courses we put in front of someone who is choosing what to study. It does not hide anything: once a learner is enrolled in a course, all of that course's material is available to them. And where a learner is old enough that their own country does not require parental consent, we deliberately offer them the adult-written catalogue too — history and philosophy written for adult readers.

The tutor is instructed to teach from your enrolled course material and to prefer it over its own knowledge, to stay in the lesson and steer back to it if the conversation drifts, and to refuse harmful requests.

Those are instructions, not guarantees, and the difference matters. We do not inspect the tutor's replies as it writes them — we tried a keyword filter that did that and removed it, because it flagged ordinary teaching about the Cold War and Socrates while catching nothing real. What we do instead is grade recorded sessions against a quality rubric afterwards and act on what it finds.

If something the tutor says concerns you, report it from inside the app and it comes to us.
