Free tools
Six free tools for people who write for a living.
All six run in your browser. Nothing is uploaded, nothing is stored, no sign-up. They are the checks we run on our own drafts before a client sees them.
Readability
Readability checker
Flesch Reading Ease, Flesch–Kincaid grade, Gunning Fog, average sentence length and the sentences that need cutting — measured on any text you paste.
Open the checker →Headlines
Headline tester
Character and word count, the words that carry weight, the filler that carries none, and a score that lists its reasons instead of hiding them.
Open the tester →Meta descriptions
Meta description generator
Five descriptions from a topic and a benefit, each counted against the 155-character limit, plus a box to check one you already wrote.
Open the generator →Invoicing
UK VAT calculator
Add VAT to a net figure or take it out of a gross one at 20%, 5%, zero-rated or your own rate. Shows the VAT fraction for the total you hold.
Open the calculator →Drafting
Word counter
Words, characters, sentences, paragraphs, reading time and the words your draft repeats most, updated as you type.

They are the checks that come up every week on real client work. Spelling variants are the fastest way to signal to a UK reader that a page was not written for them; readability is the fastest way to lose one; a headline that does not survive 60 characters never gets read; and a VAT figure that does not add up is an invoice that comes back. None of them needs a paid subscription or an account, which is why we published them rather than keeping them internal.
If you want the reasoning behind the numbers, the guides below explain where the thresholds come from and how to act on them.
- How to choose between UK and US spelling — one page, one variant, decided once.
- Plain English writing — what to cut before you measure anything.
- House style guide — the record that stops the argument recurring.
- Editing checklist — the pass that catches what the tools cannot.
