Jakssem App Launched, Providing AI and Major-specialist Performance Feedback Without the Burden of Private Tutoring Relationships

A platform has emerged where people who learn, teach, and enjoy classical music gather in one place.

Jakssem Co., Ltd. (CEO Lee Hyun-woo) announced that it has launched the specialized classical platform 'Jakssem' through the iOS, Android, and its website. Students, parents, specialist teachers, music academies, and even competition organizing associations are connected within a single app, alongside everyone involved in classical education and performance.

Until now, information and exchange in the classical field relied on academies, personal networks, and scattered communities. Jakssem has gathered performance feedback, classical content, and information on academies and competitions into one app so they can be found in one place.

Performance feedback without the burden of private tutoring relationships

The core of Jakssem is the feedback from AI analysis and specialist teachers, known as 'Jakssem.' In particular, it distinguishes itself from existing lesson-matching apps by allowing users to receive feedback from various perspectives without the burden of the private tutoring (sasa) relationship, which has been a long-standing concern in the classical music community.

Since classical music can sound entirely different depending on the interpretation and expression of the same piece, listening to feedback from multiple perspectives is important for improving skills. However, in the music community, if a student already has a teacher, it is difficult to show their performance to another teacher and seek advice. While lesson-matching apps find new teachers, for students who already have a mentor, the very act of finding a new teacher is a burden. Jakssem allows students to hear advice from different perspectives without changing their teacher.

Students only need to upload a performance video or recording without any pressure. 'Kkossem AI,' independently developed by Jakssem, diagnoses the student's current level by analyzing six items: pitch, rhythm, posture, expression, technique, and musicality. It then provides a detailed report for each item, tempo evaluation, and song information, and suggests customized practice methods including what to practice this week and daily practice times.

If they want to listen more deeply, they can request feedback from a Jakssem by uploading a performance video. Jakssem specialists, who are majors in the same instrument with verified academic backgrounds, leave opinions anonymously, adding the perspectives of multiple Jakssem to a single performance. Users can also receive 1:1 corrective guidance from a Jakssem they like.

Faces in performance videos are hidden using automatic mosaic technology, and the video is delivered only to the Jakssem leaving the feedback. Identity protection is thorough, ensuring that videos are not visible to other students or users, nor even to the teachers at the academy the student attends.

From Today's Classical to Instrument Encyclopedia

Jakssem contains classical content that users can open even on days they do not perform. 'Today's Classical' delivers audio sources and performance videos suitable for the user's instrument every day.

Stories of composers and eras, an instrument encyclopedia, and columns written by specialists can also be read within the app. Every Monday, 'Jakssem Weekly,' which contains interviews from classical education sites, is published.

Parents, teachers, academies, and competition organizers are also included

Jakssem is an app used not only by students but by everyone involved in classical education and performance.

Parents with children under 14 can check how many minutes their child practiced today and assign practice tasks. When the child opens the app, their location can also be viewed on a map.

Students and parents looking for academies do not need to search through 20,000 music academies nationwide individually; they can browse by region and instrument within the app. Reviews scattered across blogs and map services can be checked in one place without having to search elsewhere.

Specialist teachers can earn income by acting as 'Jakssem' through feedback and 1:1 corrective guidance, and can grow their own channels with lesson tip videos and columns. The identity of the teachers is also strictly protected.

Music academies can also promote themselves through their skills by leaving feedback on the performances of students nationwide, and are provided with their own customized homepages. Competition organizing associations can register competitions for free to announce them to users nationwide.

In this way, Jakssem aims for all users performing classical music—including students, parents, specialists, academies, and competition organizing associations—to gather on one platform and connect with each other. Learners obtain feedback from various perspectives, teachers get opportunities to promote their skills, and parents find ways to monitor their children's practice, all within one app.

Lee Hyun-woo, CEO of Jakssem Co., Ltd., said, "There are many people who do classical music, but there was no proper place for them to gather and listen to each other. Regardless of where they live, everyone should be able to receive diverse feedback from verified teachers."

He added, "We will make Jakssem an app that anyone who learns, teaches, and enjoys classical music opens every day, so they do not have to search for teachers, academies, and competitions one by one."

Jakssem can be downloaded by searching for 'Jakssem' on the iOS and Android stores or used directly on the website (www.jakssem.com).

Established in 2026, Jakssem is a specialized classical platform for everyone who learns, teaches, and enjoys classical music. Headquartered in Yongin, Gyeonggi-do, it provides core services such as performance analysis via the independently developed 'Kkossem AI' and feedback from specialist teachers 'Jakssem' with verified academic backgrounds. It connects students, parents, specialist teachers, music academies, and competition organizing associations in one app, and gathers necessary classical information in one place, such as the daily 'Today's Classical,' composer and instrument encyclopedias, finding music academies nationwide, and competition schedules. Jakssem aims to become a platform that anyone performing classical music opens every day by creating an environment where anyone, regardless of where they live, can receive diverse feedback from verified teachers.
