Math Ladder AI is built by a small team, and every message is read by someone who can actually change the product.
We would rather not publish a response-time promise we cannot keep at every hour of every day. What we can say honestly: reports that block a student, and anything about billing, go first.
Something broken and reproducible, sent with a screenshot, is often fixed and shipped the same week. A feature request may sit longer, but it is read and it is kept.
