No ads. No recommendation feed pulling them somewhere else. No strangers in a chat window. The only voice in the lesson is their Guardian's — and the only thing it wants is for them to get it.

Not screen time. Not a streak of green squares. Which topics they have mastered, which ones are still shaky, and what their Guardian is working on with them next.

Vektor for math. Polly for languages. Verdant for biology. Eight Guardians, each one built to teach their own subject — and to notice when your child is stuck before your child says so.
lessons they do, not watch.
A video plays whether anyone is paying attention or not. A Guildha lesson does not move until your child moves it — dragging the bond, drawing the proof, saying the word out loud. Attention is the mechanism, not the hope.

The moment
“I got it wrong again. I'm just bad at this.”

their guardian never gives up on them.
Two wrong answers? Verdant tries a different angle. Five wrong? He simplifies. Ten? He celebrates the effort and suggests another path in. No sighing. No moving on without them. No note home.

frequently asked questions.
No. There is no open chat and no public comment surface. The only conversation inside a lesson is with their Guardian. Guilds are opt-in study groups you can see, and they carry no free-text messaging to strangers.
None, on any plan — including the free one. We are paid by subscriptions, not by attention, so nothing in the product is designed to keep your child scrolling.
Which subjects and topics your child has worked on, what they have mastered, what is still shaky, and what their Guardian is working on next. Mastery, not screen time.
Learning data is used to adapt their lessons and nothing else. It is never sold, and it never trains an advertising profile. Guildha is built to GDPR, COPPA, FERPA and LGPD requirements.
Yes. Their first lesson is free and so is their hundredth. Core Guardian tutoring, streaks and the 99 question types cost nothing. Paid plans unlock unlimited AI tutoring and every Guardian.
Roughly 8 and up. Lessons adapt to the child rather than to a grade label, so a strong 10-year-old and a struggling 14-year-old can sit in the same topic and each get the version they need.
