StoichioAI vs DSE 化學溫習精讀 Chemistry Revision

StoichioAI is for Hong Kong secondary chemistry. Students write calculation steps on a whiteboard. The AI reads the working and asks questions, instead of handing over the answer. It is for students preparing for HKDSE Chemistry and for teachers who need to see how their own groups are doing. The interface, topics and AI replies can be switched between Traditional Chinese and English. English uses Hong Kong DSE chemistry wording and British spelling. Students can: Read an interactive lesson, then try the follow-up calculations Write with Apple Pencil or a finger, or submit a photo from the camera or the photo library Ask for a Socratic hint after a wrong attempt. Spoken feedback is Cantonese in Chinese and English in English Review feedback, past attempts, points, and a learning suggestion based on their own weak spots Teachers can: Create a teaching group and invite students with a join code or a school email See weak topics, common mistakes, and each student’s progress Refresh an AI suggestion for the group or for one student Preview questions and reference answers Topics include reacting masses, concentration, pH, volumetric analysis, standard enthalpy changes, Hess's law, rate of reaction, molar volume of gases, equilibrium constant, shifts in equilibrium, organic synthesis calculations, rate equation, activation energy, atom economy, separation and purification, quantitative analysis, instrumental analysis, and analytical chemistry applications. Sign in with an authorised school email. Points are awarded only the first time an exercise is answered correctly.
