WolframAlpha

Computational knowledge engine for math and science

4.3
AI Research Free plan Paid from Pro from $5 per month (annual) Web App, iOS, Android, API

WolframAlpha computes answers instead of searching pages: enter an equation, unit conversion, statistics problem or chemistry query and it returns a computed result with the method shown. Its curated knowledge base covers math, science, engineering, finance and everyday facts.

The free web version handles most quick computations. Pro (from $5/month billed annually, $9.99 monthly) adds step-by-step solutions, increased computation time, file upload for 60+ data formats and practice problems – the student favourite for actually showing your work.

Key Features

  • Step-by-step solutions (Pro)
  • Math, science, engineering computations
  • Upload and analyse data files (60+ formats)
  • Curated curated knowledge base
  • Graphing and visualisation
  • API for developers

Pros

  • Authoritative computed results, not guesses
  • Step-by-step solutions are unmatched for learning
  • Very affordable Pro tier

Cons

  • Natural-language queries take practice
  • Not a general-purpose assistant

Our Verdict

Still the tool every student should bookmark - the $5 Pro plan pays for itself the first time you need to see the steps, not just the answer.
