Common questions
Is there a free Internal Assessment grader?
iBacalao includes free monthly checks on Student Plus. Upload a draft, pick your subject, and get criterion-level feedback without generating text for you.
How is this different from ChatGPT?
ChatGPT is a general-purpose assistant and can use assessment criteria you provide. iBacalao's workflow binds each review to its configured subject/session criteria and is designed to comment on your draft rather than generate replacement assessment text.
Does it work for Biology, Chemistry, and Physics?
Yes — including the first-assessment-2025 scientific-investigation rubric. Choose your subject from the grid below.
