Boppo

Jul 2026 - Present · Independent macOS product · Released

A macOS menu-bar app that repairs wrong-input-language typing in place — before you even notice.

0
keystrokes stored or sent: 100%
on-device detection

For the moment you start typing before noticing the input language is wrong: Boppo reads a short physical-key sequence and safely repairs Traditional Zhuyin ↔ English, failing closed whenever the text context is ambiguous or cannot be verified — it would rather miss one repair than delete one character.

Commissions

Got a project? Let’s talk.

I'm a remote full-stack dev at Emat — 擴益媒體, and the day job gives me clearance to take on side projects. Open to most kinds of work — landing pages, e-commerce, sign-up / event systems, internal tools, API / payment integrations, AI-assisted features, iOS prototypes. One or two at a time — clear scope, clean handoff. Not a fit for long-term retainer / on-call support.
