WeeNote
Local desktop app that turns Korean school counsellors' monthly paperwork into minutes.
What it is
WeeNote (위노트) is a desktop program for school counsellors in Korea's Wee Class system: it keeps counselling logs, schedules, psychological test results and statistics, and exports to the NEIS system. Data stays on the school's own computer, encrypted, with optional AI drafting.
How it was built with AI
Founder Min Sang-gi, a former elementary-school teacher of about 14 years who later worked a year as a developer, says in a Korean interview that he built the first version on Replit (for the database and deployment) and now does all development in Claude Code.
