Whetstone Learning
For the global IB community
Whetstone Learning exists to put genuinely helpful, easily accessible and community-driven resources and tools into the hands of IB teachers and students everywhere. We believe the best learning happens when great teaching is supported, not replaced, so everything we build is designed to lighten the load, sharpen understanding and give educators back their most precious resource: time.
Every resource and tool we create is shaped by a team of highly experienced IB practitioners, including coordinators, examiners and classroom teachers who have lived the curriculum from the inside. That collective expertise is woven into each guide, template and feature, ensuring everything we offer is accurate, practical and grounded in the real work of teaching and learning the IB.
Your questions, answered
The doubts we hear most from students, parents, and teachers.
How is GuideMate different from ChatGPT or a generic AI chatbot?
GuideMate is built for one thing: the IB. Its agents are grounded in IB assessment criteria, rubrics, and paper formats, so feedback reads like an examiner, not a search engine. And instead of one blank chat box, you get purpose-built tools: essay evaluators that score 1 to 7 against real criteria, research question coaches, exam-style practice generators, and a Learning Center that tracks what you have actually mastered.
Does GuideMate just give students the answers?
No, and that is by design. GuideMate coaches rather than completes. Evaluators mark your draft against IB criteria and show you where it falls short and how to lift it; they never write it for you. Tests come first, then your notes reshape around what you got wrong. The point is that you improve, not that the work gets outsourced.
How does GuideMate teach students to think the IB way?
Every tool speaks IB. Feedback references the same criteria and markbands examiners use, research question coaching pushes toward focused, feasible, assessable questions the way a supervisor would, and practice papers mirror real command terms and formats. Over time students internalize how the IB rewards analysis, evaluation, and structure, a skill that outlasts any single assignment.
What are the Whetstone Learning Center and GuideMate Brain?
Together they form a complete learning loop. Drop in your course book or slides and the Learning Center builds structured study notes, then generates full IB-style tests on each chapter. GuideMate Brain maps every concept you study, tracks your mastery, and reshapes your notes around your weak areas so focused retests bring them up.
Is GuideMate free to use?
Yes, you can start free. Every new account gets free credits to spend on agents, notes, and tests, refreshed monthly. Plus and Pro plans unlock larger monthly credit quotas and premium features such as micromodules. Upgrades happen inside the mobile app.
Do I need the mobile app to use GuideMate Web?
No. You can create your free account directly on the GuideMate Web dashboard and use the agents, the Learning Center, and your library from any computer. The IB GuideMate app for iOS and Android shares the same account, and plan upgrades happen in the app.
