WolframAlpha
Wolfram
Best for: Research & Reference for people who want a checked, free option.
WolframAlpha isn't a chatbot — it computes: natural-language questions answered by the Wolfram engine's curated data and algorithms, from calculus to nutrition to unit conversions.
Free access covers basic computation; a Pro subscription adds step-by-step solutions, extra computation time, and file input. The page confirms both tiers exist; card requirement not stated.
It fits students checking math and professionals who need computed facts rather than generated guesses.
The honest limits. Step-by-step workings — the thing students actually want — sit behind Pro. Not used first-hand; confirm at wolframalpha.com/pricing.
