Sciences
Deep analysis of Physics calculations, Chemistry diagram interpretation and Biology long-answer questions, pinpointing conceptual blind spots and assessing the completeness of arguments against the marking scheme.
Handwriting recognition of equations and symbols
Students write chemical equations and scientific symbols with pen and paper, then take a photo and upload it. AI accurately recognises the scientific symbols, splits them into lines automatically, and converts them into editable digital text.
Calculation word problems
Analyses students' working in depth to pinpoint the physics concepts they have overlooked.
Precise interpretation of force analysis NEW
AI interprets force analysis on free-body diagrams, checking whether the sign, direction, and components of each force are correct, working through trigonometric ratio calculations step by step, and flagging errors in units and computation to help students consolidate mechanics concepts.
Graphical-analysis questions
AI intelligently interprets both image and text information in each question, comprehensively analysing the reasoning and accuracy of students' written answers.
Experimental apparatus diagrams NEW
AI interprets apparatus diagrams, checking whether reaction vessels, reagent labels, and gas collection methods are correct. It flags shortcomings in apparatus choice and labelling, helping students grasp the key concepts of experimental design.
Energy level diagram concepts NEW
AI reads energy level (energy profile) diagrams, checking whether the curve shape and the labelling of activation energy and enthalpy change are correct, and flagging conceptual errors to help students clarify the energy changes in exothermic reactions.
Long-answer extended-response questions
Against the marking criteria, it assesses the completeness and logic of students' answers while checking whether their arguments are clear and well-organised.
Interpreting labelled neuron diagrams NEW
AI accurately reads labelled diagrams of organs and cells, checks whether each labelled structure is positioned correctly, scores point by point against the marking scheme, and flags labels that could be added — helping students reinforce biology concepts.
Reading data-plotting questions NEW
AI interprets students' data graphs, checking whether axis labels, units, and plotted data points are accurate. It compares against the marking scheme to flag shortcomings in titles, axes, and best-fit lines, helping students master experimental data handling.

Genuine feedback from schools, teachers, and students
Physics students generally have weak written expression skills, and in the past teachers had to spend a great deal of time dealing with their writing problems. Although written responses usually account for a relatively small proportion of the marks, teachers nonetheless had to put in more effort to grade them, which was clearly inefficient. Now, with UnaGPT, the system can quickly resolve most writing problems, freeing up more of teachers' time to focus on other teaching content that carries a higher proportion of marks.
