Make Text More Casual — Stop Sounding Like a Corporate Email

You wrote an email that sounds like a press release. Or a Slack message that sounds like a contract. Or a social post that nobody is going to engage with because it reads like a corporate disclosure. The fix is simple — strip the formality, add some breathing room, and let your actual voice come through.

The free tone rewriter does this in one click. Paste the stiff version, pick "Casual," and get back something that sounds like a real person wrote it.

When Casual is the Right Choice

Casual is the right tone more often than people think. The default in business writing has drifted toward over-formal because it feels safer — but safer is also boring, and boring is the fastest way to get ignored.

Casual works best for:

• Slack and Teams messages — anything in chat should sound like a chat, not a memo
• Internal emails to teammates you actually know — formal language with people you talk to every day is weird and creates distance
• Social media posts — LinkedIn included, despite what most LinkedIn posts look like
• Marketing copy — landing page text, email blasts, in-app messaging
• Customer-facing apps with younger audiences — anything aimed at under-35 should not sound like a bank statement

Casual is the wrong tone for legal documents, executive summaries to a board you do not know personally, formal apology letters, and anything where a stiff register signals respect for the situation. Use Professional or Formal instead for those.

Before and After Examples

Stiff version	Casual rewrite
I am writing to inquire as to whether you would be available to schedule a brief meeting to discuss the project at your earliest convenience.	Got a few minutes this week to talk about the project? Whenever works for you.
Please be advised that the document has been forwarded to the relevant parties for their review.	Heads up — I sent the doc to everyone who needs to see it.
I would like to express my sincere apologies for the delay in my response.	Sorry for the slow reply.
Per our previous correspondence, I am following up regarding the outstanding action items.	Quick follow-up on those action items from last time.

Notice the patterns: shorter sentences, contractions, dropped throat-clearing phrases like "I am writing to," real verbs instead of nominalizations ("apologize" beats "express my sincere apologies"). The casual rewriter applies all of these automatically.

Tip: do not use casual when warmth is the goal

"Casual" cuts formality and adds brevity. If you want warm and personal (like for a sympathy note or a thank-you message), use Friendly or Empathetic instead. Casual can come across as too clipped for emotional content.

For more tone-specific guides see the empathetic tone guide and the confident tone guide.

Frequently Asked Questions

How do I make text sound more casual?

Three changes do most of the work: shorten sentences, use contractions ("you're" instead of "you are"), and cut phrases that exist only to sound polite ("I am writing to," "please be advised that," "as per our previous correspondence"). The free tone rewriter applies all of these automatically.

When should I NOT use a casual tone?

Avoid casual for legal documents, formal apologies, executive communication to people you do not know personally, sympathy notes, and anything where a stiff register signals respect. Use Professional, Formal, or Empathetic instead.

Is casual the same as friendly?

No. Casual cuts formality and adds brevity — it can sound clipped or detached. Friendly adds warmth — it sounds personal and approachable. For chat messages, casual is usually right. For relationship-building emails, friendly is usually right.

Will casual writing make me look unprofessional?

Only if the context calls for formality. In Slack, internal email, and most marketing copy, casual outperforms formal because it sounds human. The safest approach: match the formality level of whoever you are writing to, then dial it down slightly to feel approachable.

Does the casual rewriter work in Safari?

The tone rewriter uses Chrome's built-in AI features, so it works best in Chrome on desktop and Android. Safari and Firefox do not have native AI yet, so the tool will show a compatibility warning in those browsers.

Can I use this for LinkedIn posts?

Yes, and you should. LinkedIn posts written in casual tone consistently outperform formal ones. The platform rewards posts that read like conversations, not press releases. Paste your draft, pick Casual, see if the rewrite feels more like something you would actually say out loud.
