TeachForge.ai is the teaching studio for live lessons in any subject, face to face or online. AI can produce material in seconds, and it can be wrong. What it cannot do is teach the class in front of it. TeachForge is built for that part. At its centre is a whiteboard built for teaching. Around it sit a parametric Workshop, whose interactive objects are driven by controls rather than code and change in front of the class; Quest Ladder, active-learning questions that show how sure each learner was and choose the next step from how they answered; and Virtual Lab, where learners change an experiment and watch what happens, first in a guided demonstration, then in open what-if exploration. Learners join with a link or a code. The teacher brings their own AI and decides what the class sees: copy a prompt into the chatbot they already use, add their own key, or run their own model. Nothing reaches learners unchecked. TeachForge is for everyone who teaches live. Tutors use it for one-to-one and small-group sessions, in person or on a call. Schools use it in the classroom and for homework, with quests that run as active learning, assignments, diagnostics, spaced review or exam practice. Universities use it in lectures and seminars, and it connects to their learning management system through LTI 1.3. We believe the best lessons still come from a teacher who reads the room, asks the right question and changes course when a class needs it. Technology should make that easier, not replace it. You can start on the Free plan and move to Standard, Quest or Academy as your teaching grows. AI supplies the heat. The teacher does the forging.
