N3RD Early access Built by a biomedical sciences student, for students

A science-based tool built to improve your grades.

N3RD is a tool that uses Artificial Intelligence and science to create the perfect tool to accompany you in your studying career.

The app is built to improve your grades and maximise your understanding of the content within a given timeframe.

The app at a glance

Your lecture, rebuilt as cause and effect.

Upload a lecture and N3RD turns it into a chain of steps — this happens, which causes that — and checks every step against your slides before you see it. Everything else in the app is built from that chain.

Why does ?

    Verifying…
    What happens to your flashcards

    The same chain keeps coming back, until it sticks.

    N3RD doesn't make a pile of cards and forget about them. Every answer you give is recorded and fed back in, so the next session targets exactly what you're about to forget.

    1. Chain → cards

      Each verified step becomes questions that make you explain, predict or compare — not recite.

    2. You answer

      You grade yourself Again, Hard, Good or Easy. That grade is saved against the step it tests.

    3. The schedule adapts

      Cards you know get pushed further out. Cards you miss come back sooner — spaced repetition.

    4. Weak links resurface

      A missed card brings back the step it came from, so you re-learn the mechanism, not just the answer.

    5. Ready for exam day

      Reviews are spread across the time you have left, so everything is fresh by the exam.

    The science behind it

    Three ideas from memory research. One app.

    None of this is a gimmick. Every claim below comes from peer-reviewed research indexed on PubMed — tap a source tag to read the paper.

    Spaced repetition

    Review right before you forget

    • A review of over 300 experiments found that spacing study sessions out improves long-term retention compared with cramming.S1
    • The best gap between reviews depends on how far away the test is.S2
    • In a randomised trial, medical students who got spaced review questions remembered significantly more up to a year later.S3

    In N3RDAn adaptive review schedule, built around your exam date.

    Organisation

    Structure first, details second

    • Information that fits into a structure you already understand is usually remembered better.S5
    • Neuroscience research shows that once a knowledge framework exists, new facts can be consolidated much faster.S6
    • A review of 35 studies found that mapping how concepts connect promotes meaningful learning in medical education.S7

    In N3RDSubjects → lectures → chains, plus a mind map of every lecture.

    The knowledge tree

    Build it, then use it

    • Explaining why something happens helps students reason through problems they haven't seen before.S8
    • Testing yourself beats re-reading for long-term memory — even though re-reading feels more effective.S10S11
    • Mapping a topic helps, but practising recall of it produces more learning.S12

    In N3RDFirst the verified chain, then flashcards, quizzes and oral tests built from it.

    Six months after learning, medical students remembered more when they had explained the material — and more still when they had been tested on it.S9 A major review of 10 study techniques rated spaced practice and self-testing highest, and rereading and highlighting lowest.S4

    How it works

    Every tool, one lecture at a time.

    Each lecture you upload opens into the same workspace. Here's what every tool does — and what it looks like.

    Upload & notes

    Drop in your slides. Get clean, verified notes.

    Upload the PowerPoint, PDF, Word file or notes your lecturer gave you. N3RD writes structured notes from your material only, and highlights the key terms you'll be tested on.

    • PowerPoint, PDF, Word and plain text
    • Every section linked back to its slide
    • Key terms pulled out automatically

    1 · Establishing polarity in the zygote

    Sperm entry provides the first cue: its centrosome marks the future posterior and triggers cortical flow, which moves the anterior PAR proteins forward.

    2 · Two opposing PAR domains

    PAR-3 / PAR-6 / PKC-3 hold the anterior cortex; PAR-1 / PAR-2 hold the posterior. Each domain keeps the other out.

    Mind map

    See the whole lecture as one structure.

    A radial map puts the lecture's main idea in the centre and branches out into every concept and how they connect — the framework new details hang on.

    Flashcards

    Cards that test the mechanism, not the slide number.

    Questions ask you to explain, predict, compare and design experiments — the thinking exams actually mark. Grade yourself after each card and N3RD decides when you'll see it again. Tap the card to flip it.

    AI Teacher

    Ask anything. It answers from your lecture — and shows where.

    A tutor that knows exactly what your module covers, explains it at your level, and points to the slide behind every answer. No answers pulled from somewhere your lecturer never mentioned.

    • Grounded in your uploaded material
    • Source slides shown on every answer
    • Remembers the conversation per lecture

    Why is the anterior cell bigger if both get the same DNA?
    Because the spindle isn't in the middle. Stronger pulling forces on the posterior side drag it backwards, so the cleavage furrow forms off-centre — anterior AB ends up larger than posterior P1. Size is about where the cut happens, not what's inherited.✓ matched to slides 11–12

    Oral test mode

    Explain it out loud, like a viva.

    Talk through a mechanism in your own words. N3RD marks you on the steps of the chain you hit, the ones you skipped and the ones you got wrong.

    • Marked against the verified chain
    • Shows exactly which step you missed
    • Great practice for vivas and OSCE-style questions

    Questions

    Good questions.

    What does “checked against your slides” actually mean?

    After N3RD builds a chain, a second AI checks every step against the part of your uploaded material it came from. A step that can't be traced back to your lecture is dropped rather than shown with a warning — so a chain is sometimes shorter than you'd expect, but everything in it has a source you can open.

    What can I upload?

    PowerPoint slides, PDFs, Word documents and plain text — whatever your lecturer puts on the course page, plus your own notes.

    Is this just ChatGPT with a nicer look?

    No. General chatbots answer from everything they've ever read. N3RD works only from your course material, verifies what it produces against it, and turns it into a revision system — scheduled flashcards, quizzes, oral practice and a plan — rather than one-off answers.

    Which subjects does it work for?

    Anything with mechanisms and reasoning in it: biology, biomedical science, medicine, pharmacology, chemistry, psychology, economics and more. It started in biomedical sciences, so life-science lectures are where it's sharpest today.

    Is early access really free?

    Yes. No card needed. You'll get one email when your access is ready, and you can decide about Plus later.

    Is using N3RD allowed by my university?

    N3RD is a revision tool — it helps you learn your own course material and doesn't write assessed work for you. Always follow your university's rules on AI for coursework.
