LauraBook

The Problem

You have a 50-cell notebook. You change line 23. Which cells need to re-run?

In traditional Jupyter: 🤷 "Better run all 50 cells and wait 10 minutes."

In LauraBook: ✅ Instantly see the 4 cells affected. Run only those. Done in 45 seconds.

How LauraBook Helps You Work Better

See It In Action
