Sometimes you don't want the quick answer. You want to actually get something — to understand why it works, how it connects to everything else, and what the deep version of the idea looks like. That's what iTutor's concept explainer is built for.
Instead of a single explanation, it gives you a structured deep dive across six tabs: ELI5, intuitive, standard, university-level, expert, and related concepts. You pick the level that fits where your understanding is right now.
Six levels, one concept
Here's what each tab does:
- ELI5 — the "explain it like I'm five" version. Metaphors, simple language, no jargon.
- Intuitive — a conceptual explanation that builds the mental model without the math.
- Standard — roughly what a good textbook would say. Balanced, complete, accessible.
- University-level — formal definitions, proofs where relevant, the kind of treatment you'd get in a lecture.
- Expert — the subtleties, edge cases, current debates, and historical context.
- Related concepts — a map of what this idea connects to upstream and downstream.
You can start at ELI5 and work up, or land at the standard level and jump sideways. It's the same concept, six angles.
Why multiple levels matter
Learning research has a well-known finding: understanding comes from moving between abstraction levels, not from staying at one. If you only read the formal version, it stays theoretical. If you only read the ELI5 version, it stays shallow. The real understanding happens when you can hop between them — explaining a derivative as "slope at a point" and also as a formal limit, and seeing how both describe the same thing.
A deep dive forces that hopping. You read the intuitive version, then the rigorous one, and you start to see why the rigor encodes the intuition.
Related concepts: the hidden killer feature
The related concepts tab is easy to skip, which is a mistake. Understanding isn't a list of facts — it's a network. Knowing that eigenvectors relate to differential equations, and that both relate to Fourier analysis, is what makes a subject click.
This tab maps the connections so you can see where you are and where to go next if you want to keep pulling the thread.
When to reach for it
Use the deep dive when:
- You sort of get it and want to turn "sort of" into "actually."
- A concept keeps coming up and you're tired of faking it.
- You're prepping for an exam that rewards understanding over memorization.
- You're just curious.
The bottom line
Most study tools optimize for speed — get the answer, move on. The deep dive optimizes for understanding. iTutor gives you a way to actually settle into a concept, see it from six angles, and walk away with the kind of grasp that survives past the next exam.
