Adapt to me

GemmPen already writes structured feedback. If you want it to sound more like you, correct a few drafts and let it learn your style.

This is entirely optional. If the feedback already fits, you can skip this page.

How it works

01Review feedback

On the Review page, read the feedback GemmPen wrote for each student. Edit anything that does not sound like you.

02Corrections add up

Every edit is saved as a before-and-after pair. After 30 corrections, you have enough for GemmPen to learn from.

03One click to adapt

Hit the button below and GemmPen adjusts its writing to match yours. From then on, feedback sounds more like you.

Same quality, your voice

GemmPen default

Grammar

You wrote "the company have decided" in your second paragraph. Since "company" is singular in English, try "has decided." You are already getting the present perfect right elsewhere, which shows real progress.

your edits

With your voice

Grammar

Your present perfect in paragraph three is spot on - well done! Now look at "the company have decided" in paragraph two. "Company" is one thing, so it wants "has." You clearly know the rule - just keep an eye on collective nouns and you are golden.

Student data stays on your device

Only your corrections and the original AI feedback are used. Student essays, names, and scores never leave your computer.

Completely optional

Many teachers are happy with the default feedback style. You only need this if you want GemmPen to match your personal tone.

One model does it all: Gemma 4 reads handwriting, scores against your rubric, writes feedback, and learns your voice.
