Get Started with Google See how it works

Rubric-aware grading

Upload any rubric — Word or PDF. Claude reads it, extracts every criterion, and asks you to confirm the weights before a single essay is scored.

Batch grading in minutes

Point the app at a Drive folder or upload a zip. Every student's essay is graded concurrently against your rubric — a class set done before your next coffee.

Reports & gradebook ready to share

Every student gets a personalized .docx report with criterion-by-criterion feedback. The whole class rolls up into an .xlsx gradebook, automatically saved to Drive.

How it works

Five steps from setup to student reports.

  1. 1

    Sign in with your personal Google account

    Use your personal Gmail — not your school-managed Google Workspace. teachwithcolin requests read/write access only to files it creates, so your Drive stays private.

    School Workspace accounts are not supported — use a personal @gmail.com address.
  2. 2

    Set up your Google Drive folder structure

    In your personal Google Drive, create a folder called teachwithcolin at the top level. Inside it, create one subfolder per assignment. Folder names become assignment names in the app.

    My Drive
    teachwithcolin required root folder
    Essay 1 — The Great Gatsby
    rubric.docx ← your rubric file
    Alice_Smith.docx
    Bob_Jones.pdf
    … more essays
    Essay 2 — 1984
    add rubric & essays here…
    Rubric can be a .docx or .pdf file — any layout works, Claude parses it automatically.
    Student essays can be .docx, .pdf, or Google Docs — place them directly in the assignment folder.
    File names become student names in reports — use FirstName_LastName format for best results.

    Sync Drive & set up your assignment

    Click Sync Drive from the Assignments page. The app scans your teachwithcolin folder, finds your assignment subfolders, and auto-detects any rubric files it finds inside them.

    Sync Drive

    Discovers new folders & files from your Drive — run any time you add essays.

    Set Up Grading

    Creates the assignment and kicks off rubric parsing — takes about 30 seconds.

  4. 4

    Confirm rubric weights

    Claude parses your rubric and suggests a percentage weight for each criterion based on how your rubric is written. Review the breakdown — adjust any weights you disagree with — then confirm. This locks the scoring model for all essays in that assignment.

    Weights must total 100%. The app will warn you if they don't add up and won't let you proceed until they do.
  5. 5

    Start a grading batch & download reports

    From the assignment page, start a batch. Choose a Drive folder or upload a zip of essays. The app grades every file concurrently and tracks live progress. When complete, you'll find:

    📄
    Student reports
    One .docx per student with scores & detailed feedback
    📊
    Class gradebook
    .xlsx with every student, criterion scores & class analytics
    ☁️
    Saved to Drive
    All output files auto-uploaded to your assignment folder

Built with privacy in mind

Drive.file scope only

The app can only see files it created — not your entire Drive.

No school data

Never connects to Google Workspace or Classroom — personal accounts only.

Essays not stored

Essay text is sent to Claude for grading only — not retained after the batch completes.

Your credentials stay yours

OAuth tokens are encrypted at rest and never shared.
