Common Mistakes to Avoid
Counting with spaces when the platform doesn't
Some ad platforms count characters excluding spaces, others include them. Always check both numbers before you submit a campaign — a rejected ad costs you a day.
Pasting rich text straight from Word
Invisible formatting characters, smart quotes and non-breaking spaces travel with the paste and break your CMS. Convert to plain text first.
Writing to the maximum instead of the sweet spot
Google truncates titles near 60 characters on mobile. Aim for 50–57 so your keyword survives the cut.

Key Terms Explained
- Character limit
- The maximum number of characters a platform will display before it truncates your text. Twitter/X allows 280, Google titles render around 60 and meta descriptions around 160.
- Reading time
- An estimate based on an average adult reading speed of 200–250 words per minute. Publishers use it to set expectations above the fold.
- Whitespace normalisation
- Collapsing duplicated spaces, tabs and line breaks so pasted text from PDFs or Word behaves predictably.
- Slug
- The URL-safe, lowercase, hyphenated version of a title used in web addresses.
Why this matters
Text is the raw material of everything you publish — an ad headline, a product description, a university essay or a support reply. Getting the length, casing and structure right is the difference between copy that ships and copy that gets rejected by a character limit, an editor or a search engine.
Popular Use Cases
- Case 1Draft social posts, ad copy and email subject lines that fit strict character limits.
- Case 2Clean up notes, transcripts and pasted PDF text before publishing.
- Case 3Prep essays and long-form articles for editors, professors or publication.
- Case 4Transform copy for SEO — slugs, metadata, hashtags and structured snippets.

Frequently Asked Questions
How is this different from a grammar checker?›
Grammar tools check correctness. This checks how you will be perceived: passive-aggressive, blunt, insincere, hedging or pressuring.
Why is 'as I mentioned' flagged?›
It implies the reader failed to pay attention. 'To recap' delivers the same information without the accusation.
Should I always remove hedging words?›
In work requests, usually yes. Words like 'just', 'sorry to bother' and 'I think maybe' weaken a clear ask and invite delay.
Is the rewrite always right?›
It is a starting point. Read it once and adjust so it still sounds like you.
Is there a character or word limit in Message Tone Checker?›
Input limits and handling depend on Message Tone Checker. Check the page's field guidance; for long documents, try a representative section first and review whether the page sends text to an external service.

Yes — the related-tools panel on this page links the utilities most people open right before or after Message Tone Checker, so you can chain them into one workflow.
Does Message Tone Checker keep my formatting when I paste from Word or Google Docs?›

Yes — Message Tone Checker is completely free with no signup, watermark, trial or hidden paywall, however often you use it.
Can I use Message Tone Checker for non-English text?›
