Computational answer engine for maths, science, units and data
Wolfram Alpha is a computational knowledge engine rather than a chatbot: you enter a question or an expression and it computes an answer from curated data and a symbolic maths engine, then shows the result, related facts and often a plot. It handles algebra, calculus, statistics, unit and currency conversion, chemistry, physics, dates and a wide range of factual queries, and results are reproducible because they come from calculation rather than text prediction. Pro subscriptions add step-by-step solutions, longer computation time and file uploads. It is the dependable option when a checked numeric or symbolic result matters.

It computes rather than predicts. A chatbot generates plausible text, while Wolfram Alpha evaluates an expression or looks up curated data, which means the same input gives the same verifiable output.
Natural language parsing has limits, especially for ambiguous phrasing. Rewriting the query in more explicit mathematical form usually fixes it, and the free web interface shows how your input was interpreted.
That is set by your school or course, not by the tool. Using it to check working is common practice, while using it during a restricted assessment may break academic integrity rules.
