Tools for people who publish
Ten small, sharp tools we built for our own editorial work — word counts, readability, headlines, snippets, slugs, UTMs. Every one runs entirely in your browser: nothing you paste is sent to a server, nothing requires an account, and nothing is metered.
Analyze
Measure what you wrote — length, readability, keyword balance.
Optimize
Get the technical details right before you publish.
SERP Preview
Pixel-accurate preview of your title and description in Google results.
Slug Generator
Clean, readable, SEO-friendly slugs — diacritics handled, Arabic supported.
Case Converter
Title Case, sentence case, UPPERCASE, kebab-case and snake_case — done right.
UTM Builder
Correctly encoded campaign URLs with channel presets and mistake warnings.
Generate
Start from a proven structure instead of a blank page.
Why these tools are free
WriteZu is an SEO and GEO content autopilot: it studies a business, maps the topics worth owning, writes the articles, and publishes them — then tracks whether search engines and AI answers actually cite the work. These tools are the manual versions of checks our pipeline runs on every article it writes.
They cost us nothing to run — each one is a small piece of client-side code, so there is no server, no API bill, and therefore no reason to gate them behind a signup. Use them daily. If you get tired of running the checks by hand, the autopilot is the same rigor, automated.

The Pre-Publish Checklist
Every tool on this page maps to a line on it. 47 checks WriteZu runs before an article ships — as a checklist you can run by hand.
No spam. The checklist, then only what's worth knowing.
