What is Integralcalculator.info?
Integralcalculator.info is an educational website for calculus practice. It provides online calculators, examples, concept explanations, AI-assisted solutions, and step help for supported calculus topics.
Is the calculator free?
Yes. Free users can make up to 10 AI solve requests per day. Step-help requests do not count toward this daily solve limit. Premium is available for users who need a larger solve balance.
What does Premium include?
Premium includes 1000 solve requests for longer practice sessions. Extra step-help options are available to all users and include Explain, Why, Similar example, Common mistake, Next step, and Intuition.
Do I need an account?
You can browse public pages without an account. Registration is needed for account-based features such as Premium solve tracking. New accounts must be confirmed by email before sign in.
How do I activate my account?
After registration, the site sends an activation email using the configured SMTP settings. Open the confirmation link in that email to activate your account.
What if I forget my password?
Use the Forgot Password page. If an account exists for the email address, the site sends a password reset link based on the database email template.
Which calculators are available?
The site includes calculators for indefinite integrals, definite integrals, double integrals, triple integrals, improper integrals, derivatives, partial derivatives, second derivatives, implicit derivatives, limits, one-sided limits, series, Taylor series, Laplace transforms, inverse Laplace transforms, Fourier series, gradients, divergence, curl, and differential equations.
Do the calculators show steps?
Yes. The solution area is designed to show the interpreted input, final answer, and short step-by-step explanation blocks. All users can ask for extra explanation on any step.
Can the calculator make mistakes?
Yes. Automated math tools can misunderstand notation, variables, bounds, domains, or the intended operation. Always review the interpretation and verify important answers with a teacher, textbook, or another reliable source.
Why is there a daily request limit?
Request limits help prevent automated abuse, control solver costs, and keep the service responsive. Free users receive 10 AI solve requests per day. Step-help requests do not reduce the free daily solves. Premium users spend from their 1000 solve balance only for solve requests.
Does Premium renew automatically?
The current Premium implementation is a single 1000-solve package. Automatic renewal depends on the payment provider integration used on production.
How are Premium orders activated?
The site creates a Premium order when a signed-in user starts a purchase. A payment provider webhook or admin action should mark the order as paid, which adds the 1000 solves to the account.
Do you store calculator inputs?
Technical request logs may include calculator slug, input, request status, IP address, browser details, and timestamps for rate limiting, diagnostics, security, and service improvement.
Does the site use cookies?
Yes. Cookies or similar technologies may be used for sessions, CSRF protection, security checks, account features, advertising, analytics, and measurement where enabled. See the Privacy Policy and Cookie Policy for details.
How do I report a wrong answer or broken page?
Use the Contact Us page. Please include the calculator URL, exact input, selected variable, bounds if any, and what looked wrong.
