Frompter

A teleprompter that scrolls itself by listening to you. Speech recognition tracks where you are in the script, in 17 languages. Phone, keyboard and a second operator can all drive it at once. An Apple Watch remote comes with the iOS app, and a paid tier runs on the web and the App Store.

GYMKC

An AI fitness trainer that sets the next weight and rest after every set. On Google Play and the App Store; the weight and rest engine runs on the device, so training keeps going with no connection.

Sonetho

A technical blog about AI voice and video tools. Each post is written in Korean, translated and localised into 15 more languages, checked against the original, and server rendered at the edge.

QUICKCUT

A tool for video teams: transcription, silence removal, style guide compliant subtitles, translation and editor file export in one pipeline. If a run stops, finished steps are skipped and it picks up where it left off.

// how I work

One point of contact, start to finish.

The person you talk to is the person who builds it. Planning, design, build, release and what comes after stay with one owner, with no handover in between.

AI tools take repetitive work off the table; design, review and the final polish are done by hand.

Practically: Seoul, UTC+9. English by email and async works best.

Scope, process and after-launch support are on the services page (in Korean).
