Who it is for
Korean-speaking individuals who keep their own notes and documentation and want them retrievable from a chat prompt.
Natural language search across personal notes
Overview
TH Study is a Korean-language app built on MCP that makes one person's own writing searchable from ChatGPT. The material it covers is described broadly: development documentation, travel information, restaurant and cafe notes, and other everyday records.
The idea is consolidation. Content that would otherwise sit in several places is gathered into a single service, which the assistant then queries in ordinary language on request.
The listing also states an intention rather than a current feature: the developer plans to grow the service into a platform for personal-data SaaS and customized AI tools. What exists today is the search layer over content the account holder has written.
Korean-speaking individuals who keep their own notes and documentation and want them retrievable from a chat prompt.
The scope is deliberately personal: it searches what the account holder wrote, not a public corpus.
Availability
티에이치스터디 is listed in the ChatGPT apps directory only. 태희 이 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 티에이치스터디'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 태희 이, 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.
