Tool reviews & calculators

There are more AI study tools than any student could try, and most of the “best of” lists ranking them have never opened one. Our reviews take the opposite approach: what does this tool actually do, where does it quietly fail, what does it cost, and who should ignore it?

The free tools first. Our weighted grade calculator does the arithmetic your report card hides — and usually reveals that the category you’re panicking about barely matters.

Then the reviews: AI homework helpers for the general assistants, AI math solvers for the step-by-step tools, AI tutors, study tools for flashcards and practice, and citation generators — the category where getting it wrong hurts most, because invented sources are the fastest route to an academic-integrity meeting.
