Ank AI is an AI calculator for numbers — “ank” means number. You type a problem in plain language, the way you would say it out loud, and Ank AI picks the formula, solves it, verifies the arithmetic and shows every step so you can follow the method.

Is Ank AI free to use?

Yes. You get 5 free asks without signing in. After that, sign in with Google, email or phone (free) to keep calculating. There is no app to install.

What kinds of calculations can it do?

Percentages and discounts, GST and tax, EMI and loan interest, salary and overtime, tiling, concrete and material quantities, electricity bills, unit conversions, dates, BMI, algebra, calculus, physics and statistics. If it can be calculated, describe it in words.

Does it show the steps or only the answer?

By default Ank AI gives a clear everyday answer first — the result and what it means. If you want the formula and every step, tap Full working or ask for full working / step by step.

Can students use it for homework and exam practice?

Yes. Because the working is shown in full, it is useful for checking your own method rather than only copying an answer. Always review the steps — AI can make mistakes, so verify anything important.

How accurate is Ank AI?

Ank AI uses a leading large language model and re-checks its arithmetic in a verification step, but it is a learning aid rather than certified software. For financial, medical, legal or structural decisions, confirm the result with a qualified professional.

AI statistics calculator — mean to standard deviation

Descriptive statistics summarise a data set in a few numbers. Paste your values and ask for mean, median, mode and standard deviation; Ank AI sorts the list, identifies the middle value, counts frequencies and applies the population or sample SD formula with every intermediate sum shown. Useful for school projects, lab reports and quick checks before you trust a chart.
