Letters & Devotion teaches Algebra I as a grade 9 course of eight units and 55+ hours. An adaptive app does most of the explaining and problem-serving, and you do the parts that need a real person. It follows the Common Core State Standards.

The eight units

Linear Relationships as Rules, Graphs, and Stories. Systems of Linear Equations. Linear Inequalities and Absolute Value. Systems with Nonlinear Functions and function notation. Introduction to Quadratic Functions. Solving Quadratic Equations. Piecewise Functions and Absolute Value Graphs. Modeling with Data: Linear Regression and an Introduction to Variability.

What the parent does

You talk through why something works, check whether your child understands or is just pattern-matching, and grade the written justifications. You do not have to teach the algebra.

The goal by June

A student should be able to look at a table, a graph, an equation or a written scenario and move fluently between all four.

Wrong answers get a reason

Clara, the teacher in every lesson, reads the actual wrong answer and explains the specific mistake instead of only marking it, and the course slows down when a child struggles.

What this is not

It is one course among many. You decide which to take, which to hold back and how many to do in a day.
It is not a lecture course. An app and Clara explain and drill, and a parent reads the written justifications.
It cannot promise any college will accept a homeschool transcript. It prints one of what was taught and mastered, and your family issues it.

What grade(s)? (so their first lesson is ready)

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. Ticking the box below is how you, as the parent, 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 writes Clara's replies from the chat, the lesson and your child's first name. OpenAI turns lesson text and Clara's replies into the read-aloud voice. Spoken answers are turned into text on our own server and never sent anywhere. Our email provider sends you reports. Nobody sells your child's data or uses it for anything else.
Your rights: see everything collected from your child, have it deleted, or stop further collection at any time, from your account or by emailing our support address. If you refuse the 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 the owner of Letters & Devotion the same day.

Ticking the box below is how you, as the parent, give that consent. Full details, including how long we keep each thing: Privacy Policy (version 2026-10-09).

I am this child's parent or guardian, and I agree to the above.

Free for 30 days. No card. When the free days end, lessons pause unless you choose to subscribe, $29 a month for every child in the family. Nothing is ever charged without a card.

By continuing you agree to the Terms and Privacy Policy.

Questions parents ask

What should my child know before Algebra I?

Pre-Algebra is the grade 8 course built as its foundation. You can start a student anywhere and set the grade for each course.

Does it count toward a high school transcript?

Hours log themselves and a transcript of what was taught and mastered prints in one click. There is also a free transcript maker at /homeschool-transcript that needs no account.

What does it cost?

$29 a month or $290 a year for every child. The first 30 days are free with no card.
