How UTools works

Every public page is pre-rendered at build time for fast, indexable delivery. Interactive tools then run locally in your browser. Your files and tool inputs are not sent to an application server.

Reproducible randomization

The word-search and math tools turn a text seed into a repeatable sequence. The same settings and seed produce the same layout.

Word-search placement

Words are cleaned to A-Z, sorted from longest to shortest, and tested against the selected grid. Words may cross only where they share the same letter. The tool reports how many were placed.

Math guarantees

The answer key comes from the same problem objects shown on the worksheet.

• Subtraction swaps operands when needed so answers are never negative.
• Division builds a dividend from whole-number factors.

Handwriting limitations

Joined-script practice uses an available system script font and may vary by device. It is not a substitute for a required school letterform model.

Files and calculations

Images use the browser canvas; PDF and spreadsheet operations use locally loaded libraries. Calculators display formulas and input limits on the page. Check outputs before using them; a browser tool cannot guarantee compatibility with every file or individual circumstance.

Device tests

Microphone and camera access begins only when you click their start controls and grant browser permission. Stop or leave the page to release access. Controller readings and reaction timing are informal observations affected by hardware and browser behavior.

Printing

Print styles remove navigation and controls. Classroom worksheets use Letter or A4 pages; invoices and checklists use a clean document view. Choose Save as PDF in your browser print dialog.
