Early access

Algebra I is free while we build MasterRail v1. If something feels confusing or too easy/too hard, that feedback helps us shape the rails.

Built by a parent and engineer who believes learning should feel calm, clear, and human.

What you get now

  • Structured Algebra I rails
  • Proficiency checks + saved progress
  • Tutor Moves (hint / why / example)

In the works

  • Geometry
  • Algebra II
  • Precalculus
  • SAT/ACT Math Prep
  • Expanded mastery + certifications (later)

Pricing will come later. Right now we’re focused on building the best learning flow.

What MasterRail is

Rails (the path)

Lessons are broken into small sections so you always know what to do next—no guesswork.

Checks (quick wins)

Short problems confirm you actually got it. Miss one? You get a helpful nudge, not a shame spiral.

Tutor moves

Ask for a hint, a “why,” or a worked example. The tutor helps you learn—not just copy answers.

Who it’s for

Students taking Algebra I right now, students catching up, and adults rebuilding confidence. If you’ve ever said “I’m just not a math person,” this is built for you.
