Questions

Everything you wanted to ask

Quick answers about the tools in this category — what they cost, what they need and how they work.

Still have a question? We usually reply within one working day.

What do these checkers actually catch?
Spelling slips, missing punctuation, sentences that lost their way, a tone colder than you meant and words doing no real work. Each check is its own tool, so you can run only the one your draft needs and skip the rest.

How does the readability checker help me?
The AI Readability Checker tells you how hard your writing is to get through and points at the sentences causing the trouble. Long clauses and stacked jargon are the usual culprits. Shorten those and the same idea lands first time.

Can it tell me if my email sounds rude?
Run it through the AI Tone Analyzer. It reads back the mood your words give off, which is useful when you are annoyed and cannot judge your own draft fairly. Fix the lines it flags and send the message with more confidence.

Will it change my writing style?
Only if you ask. The AI Sentence Corrector repairs what is broken and leaves your voice alone, while the AI Vocabulary Enhancer suggests stronger words that you can accept or ignore. Nothing is applied to your text unless you choose it.

Do I have to pay for the full check?
No. Every checker here is free with no cost and no trial, and there is no premium version holding back the useful half. Run the spelling, punctuation and clarity checks over the same document as often as you like.

Do I need to sign up first?
No account or sign up is needed. The tools run as guest tools in your browser and return results in seconds. Signing in is optional and only saves your history, which helps if you keep editing the same document across a few days.

Can I keep the corrected version?
Yes. Export the cleaned text in TXT, DOC or HTML with one click and carry on in Word, Docs or your CMS. Everything works on phones, tablets and desktops with nothing to install, so proofreading on a train is perfectly doable.
