Wolfram Alpha

What is Wolfram Alpha?

Wolfram Alpha is not a chatbot. It's a "computational knowledge engine": it calculates answers using real data and mathematics instead of guessing. That makes it very reliable for numbers, formulas and facts.

Think of it as the world's smartest calculator that also knows facts.

What makes it special

• Calculated, not guessed: answers come from maths and verified data
• Shows graphs and tables: visual answers for equations and data
• Covers many subjects: maths, physics, chemistry, finance, geography and more
• Step-by-step solutions: see how a maths problem is solved (Pro feature)

What you can do with it

• Solve equations: algebra, calculus and more
• Plot graphs: draw any function instantly
• Convert units: currency, temperature, distance and more
• Compare data: population, weather or nutrition between places or foods
• Check science facts: chemical properties, planets, formulas
