A comparison written by one of the two

Clareza Academy vs CTC Math

We make one of these, so read this the way you would read any comparison written by a seller. What we can do is be specific about our own product, accurate about the shape of theirs, and honest about where they are the better answer. Their current price is on their site, not on this page, and the reason is at the bottom.

What CTC Math is

CTC Math is an online math program covering kindergarten through high school. Each topic has a short video lesson followed by practice that is graded automatically, with progress reports for the parent.

The pricing difference that actually decides it

They offer individual and family memberships. Check their site for current terms.

Clareza is $29 a month for every child in the household, month to month, with no per-child seats and no course limits. That is $348 a year whether you have one child or four, or $290 a year on the annual plan. The first 30 days are free, a card is taken and nothing is charged until day 30, and cancelling before then costs nothing.

The comparison to run is the same either way: monthly price, times the number of children, times twelve.

When CTC Math is the better choice

  • You only need math and like short video lessons. That is exactly what they are built around. Clareza has no lecture video.
  • You want a math course beyond Precalculus. Check their catalog. Clareza math ends at Precalculus.

Where Clareza is different

Every subject, not only math

Clareza covers English, science, history, health, PE, art, music, computer science and world languages too, all for the same $29.

A teacher that explains the mistake

Clara, the teacher built into every lesson, reads the answer your child gave and responds to it. A child who answers 136 to 304 minus 178 is told which column went wrong and walked through that column. She is an AI and can be wrong, which is why you can read every conversation from the parent side for 30 days.

A conversation, not a clip

Instead of a video and then questions, Clara teaches each lesson as a conversation, asking a question at each step and adjusting to what your child says.

Before your child starts: what we collect and why

We collect only what it takes to teach your child: the first name and sign-in you choose, their answers and progress, and their chat with Clara (written by Anthropic's AI, read aloud by OpenAI). Nobody trains AI on it or sells it, and you can see or delete it any time. You create your child's account yourself. Paying by card is how you give consent.

Read what we collect and why

Your consent is needed before we collect anything from your child, and we collect nothing without it. You create your child's account yourself; they never sign up alone.

  • What we collect from your child: the first name and sign-in you choose, their answers, time on lessons and progress, and their chat with Clara. Used to run the lessons, build their transcript and show you how they are doing.
  • Who else handles it: Anthropic (an AI company) receives the chat text and the lesson, with your child's first name but no last name or account details, to write Clara's replies. That is how Clara works, so it is part of the service. If you switch on answering out loud for a child, their voice is turned into text on our own server and then discarded; it is never sent to another company. OpenAI turns lesson text and Clara's replies (which can include your child's first name) into the read-aloud voice. Our email provider sends you reports about your child. Nobody trains AI on your child's data, and nobody sells it.
  • Your rights: see everything collected from your child, have it deleted, or stop further collection at any time, from your account or by emailingour support address. If you refuse the AI sharing above, Clara cannot teach, so the service cannot run. Chats are deleted after 30 days.
  • Safety: if your child writes something suggesting they may be hurt or in danger, we email you and Clareza's owner the same day.

Paying by card is how you give consent. Full details, including how long we keep each thing: Privacy Policy (version 2026-10-05).

Why there is no price for CTC Math on this page

We checked in September 2026 and the sources contradicted each other, including the companies' own pages against the review sites. Publishing a competitor's price that turns out to be wrong is unfair to them and useless to you, and any figure here would be out of date within a month anyway. Ours is above, because it is ours and we can stand behind it. Theirs is one click away, on their site, where it is current.
