Learning is not one size fits all.

Upload the test. Get the path back. Bitgil turns your child's real schoolwork into a living study guide that teaches each skill their way and gets shorter as they master it.

For parents and guardians. Opening to a small group first.

How it works

  1. Upload what's real.

    A missed test, homework, a teacher's study guide, or a teacher's feedback sheet.

  2. See what's behind it.

    Bitgil finds the skills behind each miss, in plain language.

  3. You review it first.

    You see every guide first. Nothing reaches your student until you've read it and said yes.

  4. Learn it their way.

    Explain, watch me, then you try, with instant checks and hints, not answers.

  5. Watch the guide shrink.

    Mastered skills fold into a quick review. The hard ones get more room.

Teach me another way

When an explanation doesn't land, one tap tries a different one: a picture, a story, step by step, or read aloud. Bitgil remembers what helped, so next time it starts there.

For every stage

  • Middle school (grades 6–8): short steps, private progress, no leaderboards.
  • High school: retakes, unit tests, and exam prep built from the actual material.
  • College: syllabus-based review that keeps up with the course.

Founder note

“My kid had a physics retake coming. The class guide was fine, but it wasn't written for her, so I built one that was. I watched it get shorter as she learned. Bitgil makes that for any student.”

— Derrick, founder, Jeong AI

FAQ

Is it ready?

Not yet. We're building with a small group of founding families first.

What does it cost?

Every family starts with a 14-day trial. Founding families get a lower price, locked in for as long as they stay. We'll share it before anyone pays.

Does it replace school or tutors?

No. It works alongside them, starting from what the teacher assigned.

Is my child's information safe?

Yes. Your family's information will be safe with us. Our waitlist privacy notice explains what we collect and why, and we'll publish the full Bitgil privacy policy before anyone can use Bitgil.
