Status: MVP · Co-owner: Chris
Converts IB and AP textbooks into structured study notes and exam-style questions using a multi-phase AI pipeline. The process starts with ingesting a textbook PDF — parsing its structure, chapters, and topics into a searchable knowledge base. From there, a second phase generates two types of content: pattern-based practice questions and exam-style questions that mirror the style of real IB/AP papers, including diagrams and visual elements where needed. A team of TAs (Sejong and Sunmin) reviews the output through a feedback website before content is accepted, with a 4-gate quality check that evaluates trustworthiness, coverage, difficulty calibration, and reviewer consensus.
This service is the backbone of ibGuru's content library and will eventually supply academy curriculum material through TIMS. Chris is the founding partner and co-owner of this service under the edu-brand portfolio.

AI Marker — AI red-pen marking for IB exam papers
Grades IB and AP exam papers against official markschemes. A tutor or student uploads a completed exam paper; the AI reads it alongside the relevant markscheme and returns a structured assessment — marks per question, examiner-style commentary, and specific improvement notes. The grading is markscheme-aware, meaning it understands not just whether an answer is right or wrong, but whether it hits the specific points an examiner would credit.
Currently used by IBtheTOP tutors and ibGuru tutors. Grading data from this service feeds downstream into the AI Report Writer, so parent progress reports can be grounded in objective marking results.

Handles the daily flood of KakaoTalk messages from parents at the academy. When a parent sends an enquiry — about scheduling, pricing, a teacher, a complaint — the AI drafts a reply in the academy's voice. Staff review the draft in Slack, make any edits, and approve it. The approved message is then sent automatically via KakaoTalk.
This eliminates the time spent crafting individual replies to repetitive enquiries while keeping a human in the loop for every message that goes out. Currently processing around 200 messages per day at IBtheTOP. As other academies join edu-brand as subscribers, this service scales to each of them independently.
Status: Planned (v3)
Generates personalised parent progress reports from class transcripts and marking data — written in the teacher's own voice, not from a generic template. A teacher's previous reports are used to calibrate the writing style; the AI then drafts a new report using the transcript from that class (via Classroom) and the student's latest marking scores (via AI Marker). The teacher reviews and sends.
This replaces one of the most time-consuming recurring tasks for teachers at any academy. Rather than spending an hour per student writing reports from scratch, the teacher spends a few minutes reviewing and personalising an AI-drafted version that already sounds like them.
