Insacheck is HR software for small businesses in Korea. Employees clock in from their phone with GPS, NFC stickers or QR, request leave by the hour, and sign employment contracts digitally. Managers see who is working, approve leave, and run multiple branches in one place. Every core feature is free with no seat limits and no credit card. It also connects to ChatGPT and Claude over MCP, so you can ask "who clocked in today?" in plain language, with tools scoped by role.
