What we are developing next

Less manual work.
More useful information.

Our apps already use AI services for selected tasks. We are evaluating Claude for the next stage of development; the Claude integrations below are planned.

Call Center · Planned

Turn transcripts into useful notes.

Use Claude to propose call titles, summaries and structured consultation notes for an operator to review.

Call transcript → draft summary → operator review

SortSync · Planned

Classify files in your own words.

Evaluate Claude for photo and document classification against user-defined categories, with an explanation of the suggested category.

File + category rules → suggestion → user review

Development direction, not a claim of released Claude functionality. Product availability and model integrations will be updated as they change.

The company behind these projects

IRIN Co., Ltd.

We are based in Pocheon, South Korea, and are preparing to commercialize Android and Windows tools for small-business workflows.

Built from everyday work.

Create a Call Center connects Android call events with the Windows TM_server console. SortSync helps organize photos and documents using user-defined categories.

The apps were originally developed personally by Dongwook Seo. Commercialization through IRIN is in preparation; the Google Play developer account is currently the developer's personal account.
