Why Traditional Note Apps Fail for Math ❌
You've tried these. They don't work.
Google Docs / Microsoft Word
The problem:
Typing equations is painfully slow:
To type: ∫(x² + 3x)dx
You must: Insert → Equation → [click symbols] → [arrange structure]
Time: 45-60 seconds
By then, professor is 3 equations ahead.
Handwriting? Not supported (just finger-drawn images, not convertible)
Verdict: ❌ Too slow for live lectures
Notion / Evernote / OneNote
The problem:
Math formatting options:
- Type plain text ($x^2$ as "x^2") → Ugly, hard to read
- Insert images → Can't edit later
- Use equation editor → Still too slow
Searching:
- Text search works fine
- Equation search? Doesn't exist
- "Find where I wrote quadratic formula" → Impossible
Verdict: ❌ Text-focused, not math-optimized
Handwriting Apps (GoodNotes, Notability)

Searchable Math Notes: Game Changer 🔍
The killer feature you didn't know you needed:
How LaTeX Makes Math Searchable
Problem with handwritten/image notes:
- Computer sees pixels, not meaning
- "Find $x^2$" → Can't, it's just an image
Solution with LaTeX:
- Computer sees
x^2(structured text) - "Find $x^2$" → Finds every instance
- Can search by topic, equation type, date
Real Search Examples
Search: "chain rule"
Finds:
- All notes mentioning "chain rule" in text
- All equations using composite functions
- Related practice problems
- Homework with chain rule applications
Result: Instant access to everything you learned about topic
Search: "derivative of sin"
Finds:
- Basic derivative rule: $\frac{d}{dx}[\sin(x)] = \cos(x)$
- Chain rule application: $\frac{d}{dx}[\sin(x^2)] = 2x\cos(x^2)$
- Product rule: $\frac{d}{dx}[x\sin(x)]$
- Homework problems using this
- Test questions
Result: See how concept evolved through course
Search by date: "September 15-22"
Finds: All notes from that week
Use case: "What did I miss when I was sick?"
Organization Strategies
By date: Chronological lecture notes
By topic: All calculus derivatives in one place
By difficulty: Flagged confusing topics
By source: Lectures vs homework vs test prep
