Measure your typing speed and accuracy in six languages, with net and gross WPM, consistency and the characters you miss most. The keystrokes are read from one field and never leave your browser.

Random numbers in any range, winners drawn from a list, shuffles and groups, dice, coin flips, UUIDs and tokens, all from the browser cryptographic generator. Nothing is uploaded.

Convert length, mass, temperature, volume, data, speed, pressure and 15 more categories, on exact definitions, with the formula shown and the same value in every unit. Nothing is uploaded.

Compare two texts or two files, see every added, removed and changed line with the words that moved highlighted, and export a unified diff. Nothing is uploaded.

Six templates, a live preview that matches the PDF to the pixel, eleven kinds of section and a real selectable-text export. No account, and the document never leaves your browser.

Drop a file and see what it can become. The format is read from the bytes, not the name. Spreadsheets, data, text, audio and video convert in your browser; images and PDFs are handed to the tools built for them.

Eighteen everyday calculators in one page: percentage, VAT, discount, loan, compound interest, margin, tip and more. Exact decimal arithmetic, and every result shows the formula it came from.

Twelve date and time answers: time zone conversion, a meeting planner, recurring dates, date differences, business days, age, Unix timestamps and ISO 8601. Daylight saving edge cases are named, not silently resolved.

Word and character counts, keyword density with stop words removed, sentence analysis and readability scores chosen for the language the text is in. Nothing is uploaded, and no score is shown below 100 words.
