How we work
- Private by design. Files are processed in your browser and never uploaded. Read the privacy policy for the details.
- Free, without catches. No sign-up, no watermarks on your files, no trial that runs out.
- Shows its working. Calculators explain the formula they use, and solvers show the steps, so you can check the answer and learn the method.
- Honest about limits. Where a result is an estimate, or depends on your institution's rules, the tool says so.
