Password checker

A password checker scores a candidate you already typed: length, character mix, and sometimes a match against known leaks. It does not invent a new secret. A high score is not a vault.

Password generator

Password monitor

How to use All guides

Scan the list and open the page that matches your task. Every guide follows the same shape: what the tool does, how to start it, what the controls mean, and a short FAQ built from questions readers actually send. None of the tools require an account or an installation — each one runs in an ordinary browser tab, and its guide points out the two or three things worth knowing before you press the first button.

Guides for the word counter and other writing tools

The most visited guide here explains the online word counter: paste a draft, read the totals, and see whether your essay, ad, or post fits its limit. If you write to a length requirement — school assignments, application letters, meta descriptions — start there. The guide also covers the habits that make counting useful, like checking the total before you trim rather than after, so you know exactly how much has to go instead of cutting blind.

Guides for clocks, timers, and countdowns

Most of the collection deals with time. There are guides for the stopwatch, the tally counter, the holiday countdown pages, and two longer reads that explain how time zones and daylight saving actually work. The explainers pair well with the live tools: read the theory once, then lean on the map and the converter whenever a meeting crosses an ocean. If you only ever open one, make it the daylight saving guide the week before the clocks change.

Stopwatch and timer basics — measuring up versus counting down Countdowns to Halloween, New Year, and other dates people wait for Time zones explained, and what daylight saving does to them Small tools: tally counter, coin flip, password generator, widgets

How the guides are written

Long manuals get skimmed; short ones get read. So each guide answers the main question in its first paragraph and keeps the details for people who scroll. If a page leaves your question unanswered, that is a defect by our own definition — the FAQ sections grow out of exactly those gaps, one reader at a time. A good guide is like a good referee: when it does its job, nobody remembers it was there.

Questions and answers

Are the tools behind these guides free?
Yes, all of them — including the free word counter, the stopwatch, and every countdown page. There is no premium tier hiding behind a button, and no sign-up gate in front of anything.
Do I have to read a guide before using a tool?
No. The tools are meant to be self-explanatory. The guides exist for the edge cases: the option you did not notice, the question that comes up halfway through the job.
Where do new guides appear?
On this page. When a tool or a longer explainer is added, its guide is listed here, so this index is always the complete picture of what the site can teach you.
