For students who do their own work

You wrote it. Keep the receipts.

Marvin quietly records how your work comes together — every draft, every source you read, every idea you said out loud, every line you pasted in. If a detector ever points at you, you can show your working instead of arguing about a percentage.

Piloting now with KS3 science (ages 11–14) on web and tablets. Secondary, college and university courses next.

Why do puddles disappear?Draft 7 · saved
Puddles disappear because the water evaporates: “particles at the surface gain enough energy to escape as water vapour.” On a warm, windy day this happens faster because the wind carries the vapour away. A puddle in the shade lasts longer because it gets less energy from the Sun.

Why paranoid is reasonable

One side gets AI. The other side gets accused by it.

Schools increasingly run student work through AI and similarity detectors. Students, meanwhile, are told not to touch AI at all. When the only evidence in the room is a score, an honest student has nothing to put next to it.

The checker has

A model trained on almost everything

  • Paywalled journals and news archives
  • Private and licensed datasets
  • A confidence score that looks like a fact
The student has

Their memory of writing it

  • No access to those sources
  • No record of how the work was built
  • “I promise I wrote it myself”

SUBSCRIBER-ONLY ARTICLE · BEHIND A PAYWALL
Most of a tree’s mass comes from carbon dioxide in the air, not from the soil, a finding that surprises many readers.

Correct science is written in a small number of ways. The better a student understands a topic, the more likely their sentence looks like one a professional wrote somewhere — including somewhere they could never have read. That is not plagiarism. It is agreement. Marvin gives students the evidence to say so.

How it works

Do the work the way you already do. Marvin keeps the record.

One workspace for researching, thinking and writing. Every step leaves a timestamped trace you control and can share.

1 · Research

Read and capture

Save quotes and notes from sources as you read. References travel with them into your draft.

2 · Think

Talk it through

An AI mentor asks questions to move your thinking on. It will not write sentences for you.

3 · Draft

Write, type or speak

Every revision is kept. Dictation stores what you said and the wording you chose to keep.

4 · Check

Show it’s yours

A short independent check with no mentor, so understanding is shown, not just stated.

5 · Share

Hand in the story

Submit the work with its audit trail. Your teacher sees how it was made, not a guess.

For students

On your side, and honest about it.

Marvin is built to protect students who do their own work — which means it is strict about what counts as yours. That strictness is what makes the record worth showing.

YOUCan you just write my conclusion?
MARVIN MENTOR · AII can’t write it for you, but let’s get you there. Looking at your notes, what’s the one thing your experiment showed that surprised you?

Every draft, kept

Scroll back through any version. Nothing is silently overwritten, so the path from first idea to final piece is always there.

Speak your ideas

Think out loud and dictate. Marvin logs the transcript and the words you confirmed. Raw audio isn’t kept.

Sources stay attached

Captured quotes carry their reference wherever you move them, so quoting properly is the easy option.

Pasting is allowed, and labelled

Paste from anywhere. It’s marked “external paste — lineage unknown” so nobody mistakes it for something it isn’t.

Works offline

Keep assignments on your tablet. Your record syncs when you’re back online, with the sync status always visible.

Your record, your case

Export the trail for any piece of work. If you’re ever questioned, you walk in with evidence.

For schools & universities

Review the process, not a percentage.

Detectors give you a number and no way to check it. Marvin gives you the timeline behind a submission: what was typed, spoken, quoted, pasted and asked — so an academic-integrity conversation starts from evidence.

Evidence, not verdicts

No similarity scores, no “verified human” badge. Marvin shows what happened and leaves judgement with the people who know the student.

Records that don’t move

Assignment briefs and session snapshots are fixed when issued. Revisions are appended, never rewritten, so the trail can be trusted later.

Assistance you set

Decide how much mentoring each task allows, and gate the independent check so it happens without help. Every assist is logged.

What Marvin won’t do

A record is only useful if it’s honest.

  • Write it for youAsking for finished work gets a guiding question back. Always.
  • Score your originalityNo invented percentages. We think there are enough of those already.
  • Claim proof of authorshipTyped or spoken doesn’t automatically mean original, and we never say it does.
  • Keep your recordingsSpeech becomes text you confirm. Raw audio isn’t stored.
If machines are allowed to judge students’ work, students deserve evidence that answers back.

Marvin is made by Immerso Gnosis, who believe the fair answer to AI in education is transparency on both sides: students learn with honest help, and educators see how the learning actually happened.

Questions

Things people ask first

Does Marvin prove I didn’t cheat?

No tool can honestly prove that, and we won’t pretend to. Marvin gives you a detailed, timestamped record of how your work was made. That record is strong evidence to put in front of a teacher — far stronger than a promise — but the judgement stays with people.

Can I use AI in Marvin at all?

Yes, as a mentor. It asks questions, points you back to your notes and sources, and helps you think. It won’t write or rewrite your work, and every conversation is part of the record, so your teacher can see exactly what help you had.

What if I paste something in?

You can. Pasted text is labelled “external paste — lineage unknown” and that label stays in the record even after you edit it or add a reference. Being upfront is what makes the rest of your record believable.

Who can see my audit trail?

You, and the teachers on assignments you’ve been given or submitted. You can export the record for any piece of work yourself.

Does it replace our plagiarism checker?

It doesn’t have to. Many schools will run both. Marvin adds the thing a checker can’t provide: the process behind a submission, so a flag can be investigated rather than simply believed.
