Practice coding problems with spaced repetition from your terminal.

hone is a macOS CLI that tracks your LeetCode, NeetCode, and GeeksForGeeks sessions, schedules problems using the SM-2 algorithm, and keeps you practicing the right things at the right time. Open a problem in your browser, submit it, and hone records the result automatically.

How it works¶

hone                    # open the dashboard
hone practice           # pick and launch the next due problem
hone add <url>          # add a single problem by URL
hone import file.txt    # bulk import with playlist grouping

The spaced repetition engine schedules each problem based on how quickly you solved it and how recently you attempted it. Problems you struggle with come back sooner; problems you've mastered fade into the background.

Quick start¶

brew install pricklywiggles/hone/hone

git clone https://github.com/pricklywiggles/hone
cd hone
go install .

Then add your first problem and start practicing:

hone add https://neetcode.io/problems/two-sum/question
hone practice

Features¶

• Automatic result detection — hone monitors your browser for submission results; no manual input needed
• SM-2 scheduling — quality is derived from your solve time, not self-reported ratings
• Playlist grouping — organize problems by topic, week, or any other dimension
• Stats dashboard — tabbed TUI with per-topic progress, streaks, and due counts
• Bulk import/export — import from a URL list file; export + restore with full JSON backup
• Zero infrastructure — single SQLite file, no accounts, no network access beyond the problem sites
