Who it is for
Piano students and anyone drilling chords, intervals or tempo without an instrument nearby.
Overview
Piano 1024 puts a keyboard in the chat window and synthesises each note as it is tapped, with no sample library or installation involved. Songs are learned in short phrases, with fingering shown and hands practised separately.
Beyond practice, the app builds chord progressions and melodies that carry across a conversation, names a chord by ear, and runs a metronome in any meter. Graded drills cover intervals, chords and scales for ear training.
It belongs to a set of music tools from the same developer that share the 1024 name.
Piano students and anyone drilling chords, intervals or tempo without an instrument nearby.
Every sound is generated live on an in-chat keyboard, so no audio files or external device are needed.
Availability
Piano 1024 is listed in the ChatGPT apps directory only. Kyung-Hoon Kim has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Piano 1024's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Kyung-Hoon Kim, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
