1.What this site is
tooldura is a collection of 41 small utilities across 9 categories: counting words, formatting JSON, generating passwords, converting units, checking how a page title will look in search results. Each one does a single job and asks nothing of you before it works.
2.No account, no setup
There is nothing to sign up for and nothing to install. You open a tool and it is ready: no sample data to clear first, no wall asking for an email before it shows you a result, no trial that expires. That applies to every tool here and it is not going to change, because the moment a tool needs an account it stops being the quick thing you reached for.
3.Where the numbers come from
Getting a number roughly right is easy. Getting it right at the edges means reading the specification. The length converter works from defined ratios, so an inch is exactly 25.4 millimetres and not a rounded decimal. The social counter weights characters the way X does and bills every link at 23, whatever its real length. The meta length checker measures rendered pixels, because search results are cut on width rather than on a character count. The password generator draws from the browser's cryptographic randomness, never from Math.random. Where a published standard exists, the tool follows it.
4.What gets built next
There are 41 tools here rather than two hundred, and every one of them works. A tool goes up when it does its job properly, not when a category looks empty, so nothing on this site is a placeholder for something planned. You will not find a link that leads to a "coming soon" notice, and no category is padded out with tools that do not exist yet. New ones arrive when they are worth using.
5.Why the guides exist
Every tool on tooldura has a written guide behind it, and those guides exist because the tools raise questions the interface cannot answer. Why two word counters disagree. Why an emoji costs two characters. Why MD5 is broken for security but fine for checksums. The guides are written from primary sources and standards documents rather than summarised from other blogs, and each one names the specifications, studies, or incidents it draws on.
6.Corrections and requests
If something here is wrong, tell us and it gets fixed. Technical writing ages, platform limits change, and standards get revised. Corrections, bug reports, and suggestions for new tools all go to devalex019@gmail.com, and every message is read.
