None of these rewrites throws the original away. The point stays the same; the decoration comes off and something a reader can check goes in its place. That is why the fixed versions are usually shorter. Short is not the goal, it is what is left once only the content remains.

The numbers in the rewritten versions are placeholders to show the shape of a good sentence. In your own work, only use figures you actually have.

Essay or report paragraph

In today’s ever-evolving digital landscape, social media plays a pivotal role in shaping teenage identity. Moreover, it’s not just a pastime — it’s a powerful force that underscores how young people see themselves.

Social media changes how teenagers see themselves. In a survey of 210 students at our school, 64% used it for more than two hours a day, and most said they compared themselves to friends rather than celebrities.

Gone: the stock opener, “pivotal role”, “moreover”, the not-X-but-Y line and “underscores”. In their place: the claim, then evidence a reader can check.

Overall, this analysis showcases the multifaceted nature of the issue and highlights the need for further research.

The survey cannot tell us whether heavy use causes low self-esteem or the other way round. A follow-up with the same students next year could.

A good conclusion names the limit of what you found. That is more useful to a marker than a promise of “further research”.

Cover letter

I am a passionate, detail-oriented team player with a proven track record of success. I am confident that I would be a great fit for your dynamic organisation.

Last summer I rebuilt the stock spreadsheet at the café where I work, which cut closing time by twenty minutes a night. I’d like to do that kind of work on your operations team.

Recruiters skim past adjectives they have read a thousand times. One specific thing you did, with a result, says “detail-oriented” without the word. The experience has to be yours, and the tool will never invent one.

Let’s dive in! Lisbon is a vibrant, bustling, and breathtaking city that boasts stunning views. And the best part? It’s not just a trip — it’s a journey. Let that sink in.

I spent five days in Lisbon in October. My hotel was up in Alfama, a lot of stairs from everything, and the views from the top made up for it.

The rewrite drops the hook, the triple adjectives, “boasts” and the closing one-liner. Readers stay for the stairs and the view, not the exclamation marks.

In this post, I’ll walk you through 5 game-changing budgeting hacks that will transform your finances. Let’s get started!

In my second year living alone I cut my food spending from $400 to $290 a month. What worked was not bulk buying. It was shopping on the same day every week.

The stock intro became a number and a finding. Whether people read to the end is mostly settled in the first two lines.

Email to a professor

I hope this email finds you well. I am writing to inform you that I would like to utilize the extension policy in order to submit my essay at a later date. Please do not hesitate to contact me should you require any further information.

Dear Professor Miller, I’m in your Tuesday seminar. Could I use the 48-hour extension for the essay due on 20 November? I can submit by the 22nd. Thank you.

Who you are, what you are asking and the date all fit in three short sentences. “Utilize” became “use” and then disappeared; “in order to” went too.

Thank you so much for taking the time out of your busy schedule to meet with me. I truly appreciate your invaluable guidance and look forward to further opportunities to learn from you.

Thanks for meeting with me today. I’ll read the two papers you suggested this week and bring my notes to Thursday’s seminar.

A thank-you note lands better with one line about what you will do next. It shows you were listening, which a string of superlatives cannot.

The order to work in

Trying to fix everything at once is how you lose your own voice. Remove the obvious leftovers first: chat phrases, asterisks, emoji. Then shorten wordy phrasing. Then look at the last sentence of each paragraph, where the stock morals hide. Working in that order keeps the change rate low while the piece gets much easier to read. When you finish, read it aloud. Wherever you stumble is where there is still work to do.

Questions people ask

Will editing this way get my essay past AI detectors?

That is not what the tool is for, and no tool can promise a detector score. It points out phrases that make writing hard to read. Check your course rules on AI use before you start.

Is my text uploaded anywhere?

No. Everything runs in your browser. Your text is saved only on this device, and the Clear button removes it.

Can it change numbers or names by mistake?

Numbers, quoted passages, links and email addresses are locked. Automatic fixes only cover swaps that do not change meaning, such as “utilize” to “use”.

Will it write my cover letter for me?

No. It flags empty phrases; the experience that replaces them has to come from you.

How much should I change?

The tool warns you when more than 30% of the text has changed. Past that point your own voice tends to disappear.
