No second AI subscription
Use the AI app your family already has for MathLens’s assisted features.

Codex
ClaudeAI-assisted lessons, Knowledge suggestions, feedback, and replies use a parent’s own app and sign-in. MathLens does not bundle those tools or a second AI plan.
The parent manages setup and access.
Student feedback
What students might say
Example names and comments are illustrative.
“I didn’t just get the answer. I learned where it came from, and why the steps work.”
“I like seeing the picture and the numbers together.”
“Now I know why we split the multiplication into smaller parts.”
“I got to try it myself before I saw the answers.”
“Working through one step at a time makes it less confusing. I can take my time and think.”
“I found my mistake and knew what to try next.”
“Practicing a similar problem helped the idea stick.”
“Now I understand why the formula works.”
“It’s easier when the formula has a picture to go with it. Then I can remember what it means.”
“I can see what to try next instead of guessing.”
“Math feels less like memorizing and more like understanding.”

Questions, answered
What does MathLens check?
Relative speed and bounded whole-number multiplication can be checked on this Mac. Other skills use saved questions or AI candidates that remain discussion practice until MathLens checks them.
Does MathLens include an AI assistant?
No. AI-assisted features use a parent’s Codex or Claude app and sign-in. A reply is a conversation, not a checked answer.
Does MathLens grade mastery?
No. Progress shows saved answers, topics, and practice days. Scores are estimates, and topics without observed evidence are marked not assessed yet.
What works offline?
Saved lessons, Library search, and practice work offline. Saved lessons can be exported as HTML. MathLens requires macOS 14 or later.
