65%
of surveyed students blank in exams despite extensive study
The Method
Utilises proven memorisation techniques used by medical students, world memory champions, and TED Talk speakers
100
Irish LC and JC students surveyed, confirming the problem is widespread
The Method
How Stuck-In Works
Every lesson is built on the Method of Loci, one of the most validated memory techniques in existence.
1
Enter the Scene
Each lesson is a hand-illustrated scene where every character, object, and action encodes a specific curriculum fact: its name and what it does. Nothing in the image is decoration.
2
Lock It In
A guided walkthrough reveals each element one by one, building the full scene in your memory. Every fact comes from the SEC marking scheme, so what you learn is exactly what earns marks.
3
Prove It
Past paper questions test your recall. When you need a hint, the scene comes back. When you see the answer, the relevant part of the image is highlighted, reinforcing the connection.

Cell Organelles
Leaving Cert Biology
Lesson Summary
Cell organelles are the specialised structures within a cell that carry out specific functions.
In this lesson, the prison memory palace separates plant-only organelles (left cell) from shared organelles (right cell).
Every visual element in the scene encodes both the name of the organelle and its biological function.

Our Story
About Stuck-In
A visual memory platform for Irish students, built by someone who understands what it means to have too much to remember and not enough time.
Why We Built This
The problem is not effort. It is method.
Stuck-In was built by an Irish medical student who knows what it means to face a high-stakes exam with an enormous volume to memorise. The Leaving Certificate is one of the most memorisation-intensive curricula in Europe. Yet every resource available to students relies on passive methods: rewriting, highlighting, re-reading. These create an illusion of learning without building durable memory.
We built Stuck-In because a better tool exists. It has existed for thousands of years. Students just have never had access to it in a form built for their specific curriculum, their specific exams, and their specific pressure.
The Science
The Method of Loci
The Method of Loci is one of the oldest and most validated memory techniques in existence. Used by ancient Greek orators, modern memory champions, and medical students worldwide, it works by anchoring information to vivid spatial locations inside a mental scene. When you walk through that scene, the information comes with it.
Every Stuck-In lesson is a hand-illustrated scene where each element encodes a specific fact: both the name of the concept and what it does. The image does the remembering. You just have to look.
Spatial Memory
The brain retains location and visual detail far more reliably than abstract text. Placing facts in a scene exploits this innate capacity.
Dual Encoding
Pairing a visual with a spoken label creates two separate memory traces. Both must fail for recall to fail.
Emotional Resonance
Vivid, unusual scenes are remembered more reliably. Every Stuck-In scene is designed to be distinctly memorable.
Our Commitment
Human-made. Always.
All content on Stuck-In is hand-illustrated by human artists. This is a deliberate choice, not a constraint. Research consistently shows that people form stronger emotional connections with human-made art than AI-generated imagery, and emotional connection is exactly how memory works.
Our customers are 16 to 18 year olds who have grown up entirely surrounded by AI-generated content, can detect it intuitively, and have documented negative emotional responses to it. We built the product accordingly. When a student believes a human spent time crafting something specifically to help them remember it, they perceive it as more valuable, more credible, and more emotionally resonant.
Where We Are
NovaUCD. Starting with Biology.
Stuck-In is an Irish product, built for Irish students, covering the Irish Leaving Certificate curriculum. We are launching with Biology and expanding subject by subject as the content library grows.

Frequently Asked Questions
What is the Method of Loci?⌄
The Method of Loci, also called the memory palace technique, is a memorisation strategy that involves placing information inside a vivid imaginary scene. Each element in the scene acts as an anchor for a specific fact. When you mentally walk through the scene, the facts come with it. It has been used for centuries by orators, scholars, and memory champions, and it is the technique that underpins every lesson on Stuck-In.
How does the quiz hint system work?⌄
On the quiz page, when you are given a question, you can click the Hint button to see the full memory palace illustration. This prompts you to find the answer yourself within the scene before selecting an option. After submitting, the correct answer is revealed along with an explanation and a reference back to the relevant part of the image.
Which subjects are available?⌄
Stuck-In currently covers Leaving Certificate Biology, with Cell Organelles available as the first complete lesson. Additional Biology topics are in production. Chemistry, Geography, History, and Physics are on the roadmap. Use the contact form below to request a specific topic.
Is Stuck-In free?⌄
The Cell Organelles lesson is available free with no account required. Full access to the content library, QBank, and games will require a subscription. Pricing will be announced at launch and positioned well below the cost of grind school fees. Sign up to the waitlist to be notified first.
Why is the content hand-illustrated and not AI-generated?⌄
This is a deliberate product decision. The Method of Loci only works when the scene is emotionally resonant. Research shows that people form stronger emotional connections with human-made art than AI-generated imagery. Our students are digital natives who can detect AI content intuitively and respond negatively to it. Everything on Stuck-In is made by human hands.
