AI-powered learning through recursive exploration
Infinite-depth knowledge exploration is here
Read. Highlight. Drill Deep.
Highlight any text you don't understand. AI generates deep explanations right where you need them. Drill layer after layer until you truly get it.
The borrow checker ensures memory safety at compile timeDrill without needing a garbage collector. Rust achieves this through its ownership system...
Memory safety at compile time means the compiler checks your code for memory errors before it runs. Unlike languages with garbage collectors (Java, Go), Rust catches dangling pointers, double frees, and buffer overflows during compilation — zero runtime cost.
...which means programs written in Rust have performance comparable to C while being significantly safer.
The old way vs. the Drill way
Without Drill
- Read article, hit confusing term
- Open new tab, Google it
- Read 3 more articles to understand
- Forget where you were
- 20 tabs open, context lost
With Drill
- Read article, highlight confusing text
- AI explains it right there
- Drill deeper if needed
- Zoom out when done
- One page, full context, always
Three steps to understanding
No setup. No prompt engineering. Just read.
02
Highlight & Drill
Select any text you don't understand. Click Drill. AI generates an explanation right below the highlighted text.

Each explanation can be drilled further. Build infinite-depth knowledge trees. Zoom out anytime to retrace your steps.
Built for people who learn by reading
Programmers
Reading Rust docs and hit "borrow checker"? Highlight it. AI explains ownership, lifetimes, and move semantics — with code examples — right in the doc.
“I drilled 4 layers deep into Rust lifetimes and finally understood them. No Stack Overflow tabs needed.”
Students
Studying quantum mechanics and "wave function collapse" makes no sense? Highlight, drill, get a clear explanation. Keep drilling until the math clicks.
“Drill turned a 3-hour study session into 45 minutes. I actually understood the material.”
