The problem

It's the end of term, and you're running on empty.

Marking is stacked up, exams are running, events eat your evenings — and then the comments. Thirty, sixty, a hundred of them, each meant to be personal and fair. But the detail that made each child them has faded, so you rush, repeat phrases, and lose another weekend.

The enemy isn't you. It's the blank page at the worst time of year. Cai Comments removes it.

Features

Everything you need to write better comments, faster.

All on-device. Nothing about your students is ever uploaded.

Per-student notes

Jot quick dated observations — behaviour, marks, incidents, small wins — as they happen.

AI-drafted comments

Turn your notes into faithful semester comments, with a draft→verify pass and tone, length & audience controls.

Instant recall

Ask "What did Sam get on the maths test?" — grounded answers from that one student's entries only.

Whole-class comments

Write once, personalised per student by name and gender — the whole class in one pass.

Voice notes

Dictate observations between lessons — transcription runs locally, offline.

English ↔ 简体中文

Full UI, models and report output in both languages — built for bilingual classrooms.

Privacy by design

Your students' data is yours alone.

Most "AI for school" tools upload children's data to the cloud. Cai Comments never does — because it never needs to. Everything runs on your computer.

  • Offline by default. Classification, recall, drafting and transcription all run on-device.
  • No student data ever leaves. Names, notes, marks and photos live only in a local file on your device.
  • No accounts to set up for students. No IT sign-off needed to start.
  • Suited to FERPA / GDPR / COPPA-conscious schools. Because the data stays with you.
How it works

Log the year. Let the comments write themselves.

Log quick notes

Through the term, add short dated entries per student — type or dictate, in seconds.

AI drafts, faithfully

At report time, on-device AI turns your notes into personal comments — grounded in what you actually observed.

Edit & export

Tweak the tone, make it yours, and copy or export. You're the author; the AI just does the heavy lifting.

FAQ

Questions, answered.

Yes. Note classification, recall, comment drafting and voice transcription all run on your computer with a bundled on-device model (a one-time ~1.6 GB download on first run, then a quick activation). After that, normal use makes zero network calls — it works on a train or in a remote school.
It never leaves your device. Names, notes, marks and photos are stored only in a local file on your computer. Our servers never receive any student data — only your account email and licence are online.
No. It's a direct download you install yourself, with no student accounts to provision and no cloud service to vet. Activation is a one-time online step; after that it runs offline.
It's a one-time purchase per device — no subscription, and it never expires. Every purchase is backed by a 14-day money-back guarantee. Launch pricing will be announced shortly; get notified above.
