Informazions su la estension

Leechboard is a local-first browser extension that puts a focused, Excalidraw-like whiteboard beside coding problems on LeetCode, CodeChef, and Codeforces.

It is designed for the moment when a solution needs a quick sketch: draw a graph, annotate a recurrence, trace an array, or leave a note for later. Boards are isolated per problem and stored in the browser profile. No account, backend, analytics, or remote content is required.
