Utilities — 4 free browser-based developer tools including Character Difference Counter, Regex Escape and Epoch Converter. Everything runs locally with no signup or uploads, so your data stays private and results are instant.
How to Use
- 1Measure the text first— Text Statistics counts words, characters, sentences and paragraphs and estimates reading time, which is what you want before writing a meta description or a post.
- 2Compare two strings character by character— The character difference counter finds the single invisible difference — a trailing space, a non-breaking space, a look-alike Unicode letter — that makes two seemingly identical strings fail a comparison.
- 3Convert timestamps and escape literals— The epoch converter turns a Unix timestamp into a readable date in your chosen timezone and back, and Regex Escape neutralises the metacharacters in a string so it can go into a pattern as literal text.
Frequently Asked Questions
Because characters like the dot, asterisk, parentheses and brackets change what the pattern means: searching for 3.14 unescaped also matches 3x14, since the dot stands for any character. The Regex Escape tool turns any literal text into a safe pattern, which matters most when the search term comes from user input.
A Unix timestamp has no time zone at all — it simply counts seconds since 1970-01-01 UTC. The converter shows the same number rendered both in UTC and in your local time, which is usually enough to tell whether a bug is a wrong value or a nine-hour time zone mistake.
It reports characters with and without spaces, words and sentences, plus an estimated reading time and the ten most frequent words, and it counts Korean syllables separately. That makes it useful for checking a meta description against a length budget or spotting a word you have overused in a draft.
