A tutor that learns how you learn.

StudyLens knows your courses, checks your homework on any page, and teaches you in an overlay right where you're working.

Get started free Watch the demo

Free for students. Works in Chrome, Edge, Arc and Brave.

See it work

Each clip is the real product on a real worksheet. Captions walk you through it.

Checks your work on any page

On Kami, a PDF, Google Docs or an online problem set, press Check. StudyLens circles the mistake right on the page and asks the one question that fixes the thinking behind it.

  • Finds the belief behind the error, not just the error
  • Marks follow the page as you scroll
  • Says so when it can't read your writing

Explains with visuals you can watch

Ask about anything on your screen. Answers arrive with worked steps, graphs and diagrams that animate in, pitched to how you learn.

  • Sees your screen when you allow it
  • Grounded in your own course materials
  • Guides you instead of handing over answers

Practice written for your mistakes

Every set targets the misconception behind something you got wrong, then comes back on a spaced schedule so it sticks.

  • Graded on the server, so answers stay hidden
  • Two right in a row clears a mistake
  • Reviews arrive right before you'd forget

Knows your courses

Open Canvas or Google Classroom once. Deadlines, grades and course pages sync through your own login, with no school setup.

  • Canvas and Google Classroom
  • Notices new work, moved deadlines and grades
  • No tokens or admin approval

Works inside Claude

Connect StudyLens to Claude and it reads your profile before it teaches, then saves what it learns about you for next time.

  • Your skills, mistakes and deadlines in every chat
  • One command in Claude Code
  • Works with Claude Desktop too

How it learns how you learn

Three things feed one profile that every part of StudyLens, and Claude, reads before it teaches you.

Your courses
New assignments, moved deadlines and posted grades
Your work
Checked homework, practice answers, and how you work when you allow it
Claude
What Claude notices about you in conversation

Recent evidence counts most. Asking about a topic never counts as being bad at it. You can read and edit your profile any time.

Private by default

StudyLens learns from your schoolwork, not your life. Everything beyond checking your work is opt-in, and you can export or delete it all.

Never records what you type or what's on a page
Never runs on email, banking, health or password sites
Screenshots only when you press Check, never stored
Export or delete your data in one click

Start with your next assignment.

Set up takes about two minutes.
