# Polarbear AI > We hate studying more than you do. ## About Polarbear AI is a student-first AI learning platform for Australian senior-secondary (Year 11-12) students. Founded in Melbourne, Australia, we pair free, source-cited ATAR and curriculum guides with an AI study app (essay marking, exam practice, an AI tutor and more). Started with VCE (Victoria) and now covering all six state certificates: VCE (VIC), HSC (NSW), QCE (QLD), WACE (WA), SACE (SA and the NT, where it is issued as the NTCET) and TCE (TAS). ## Team - CEO - Haobo: Tutoring company founder with a 100k+ student audience on socials and prior edtech experience; focused on student needs and learning behaviour. - CTO - Percy: Former Airwallex engineer with 7+ years of AI and backend experience; builds Polarbear's scalable AI systems. Backed by Antler, a global early-stage VC. ## Free tools (no ads, no sign-up) Every figure is traced to an official source and the report year; each page cites it. - VCE ATAR Calculator: https://www.trypolarbear.com/tools/atar-calculator - indicative VCE ATAR estimate with official 2025 VTAC scaling applied.

Note on honesty: where an admissions centre does not publish the data needed for an exact marks-to-ATAR calculator (UAC for HSC, QTAC for QCE, SATAC for SACE/NTCET, the University of Tasmania for the TCE), we publish only what is official and do not fabricate a calculator. TISC (WACE) publishes no raw-mark-to-scaled-score conversion either, so the WACE calculator starts from scaled scores rather than raw marks. ## AI study app - Essay Marking: instant examiner-style feedback on essays (VCE, HSC and QCE rubrics). - Exam Cram: fast AI revision for any topic. - Tutorbear: an AI tutor for every subject. - Also: Notetaker Bear (AI class notes), Storagebear (file storage), Study Rooms, and browsing approved tutor listings for 1-on-1 lessons. ## Comparisons Compare Polarbear with other study tools: https://www.trypolarbear.com/blog?category=Comparisons#articles ## Contact - Website: https://www.trypolarbear.com - About: https://www.trypolarbear.com/about - Tools: https://www.trypolarbear.com/tools - Email: haobo@trypolarbear.com
