Quick math for problem sets, length checks for written work, formatting for the submission.
For the parts of student life that involve running numbers or hitting word limits: grade percentages, due dates, age gaps for group work, BMI for a health class, length checks against an assignment brief, and the formatting the rubric actually penalizes for. None of it leaves your device until you paste the answer in.
Each card below is a page in its own right - it walks through what the tool does for Students working on assignments and problem sets, why you would reach for it over the alternatives, and answers the questions that come up most often. Click through to use the tool, or read the page first to decide which one fits.
No. Word counting, case conversion, lorem generation and slug making run entirely client-side. The only tool in this group that asks a server for anything is the AI summarizer, and that only sends the text you select when you click the button.
Yes for the common cases (percent of a number, date arithmetic, age from a date of birth, loan/installment, BMI). For physics or stats work, the rounding mode matches what your instructor is most likely to accept - usually 4 decimal places with bankers' rounding. For academically disputed formulas (BMI thresholds especially) the tool does not pretend to be authoritative.
Yes. Everything is plain HTML and JavaScript served from the edge with no installer, no extension, no account. On a locked-down school device the typical blockers (install restrictions, login-walled tools) are not a problem.
