How to Use Quillbot to Rework Copy and Keep Brand Terms

The short answer: if one approved 90-word paragraph has to become three channel versions without its product names changing, you need Quillbot Premium, because Freeze Words is Premium; the checks barely touch its allowance, 3 x 90 = 270 words of the 25,000 a month in the Plagiarism Checker article. Paste one approved paragraph into the Quillbot Paraphraser, set the English variant your market reads, freeze the brand and product names before you paraphrase, pick a mode for each channel, rephrase until an editor would sign it off, run the grammar and plagiarism checks, and export.

The job: one paragraph of copy has been through legal and the brand team, and now it is needed in three shapes. Shorter for a paid social ad, simpler for a customer email, more formal for a partner deck. Rewriting it by hand three times is where product names drift and claims grow. This guide uses Quillbot for that job; the Quillbot glossary entry covers what else the product does.

Before you start

Three things on the desk:

1. The approved source text and a frozen-terms list. Write down every word that must not change: brand and product names, plan names, any claim legal approved word for word.
2. The arithmetic for checks. For example, three variants of a 90-word paragraph are 3 x 90 = 270 words to run through the Plagiarism Checker, a sliver of the 25,000 words a month that the Plagiarism Checker article gives Premium.
3. A plan for the free version. The two free modes, Standard and Fluency, come with limited daily paraphrases, per the modes article. That is enough to try this job once on the free plan before you decide on Premium.

Step 1: Choose the language and the English variant

Open the Paraphraser and set the language from the menu inside it. The Paraphraser works in more than 25 languages, and English comes in four variants: American, British, Canadian and Australian, per the language article. For a UK campaign, pick British English first, or the rewrite will quietly change "organise" to "organize".

Step 2: Put the approved text in

Type, paste or upload a DOCX or TXT file into the left-hand box, as the Paraphraser guide describes. Work one paragraph at a time. Short inputs make it easier to see what changed and why.

Step 3: Freeze the brand terms before you paraphrase

This is the step that protects the job. Freeze Words, a Premium feature in the lower left corner of the input box, keeps the words you list unchanged. Open it, type the terms separated by commas, and click the arrow to add them, per the freeze words article.

Two details from the same article decide whether it works. Add the words before you paraphrase, not after. And symbols, special characters and dashes are not supported, so a hyphenated product name or a trademark symbol cannot be frozen; check those by hand in step 5. Freeze Words is also not available in every mode, and the tool switches off when the chosen mode does not support it.

Step 4: Pick a mode for each channel

The modes article lists ten modes. For this job, three do most of the work:

• Shorten for the ad, which cuts length while keeping the meaning.
• Simple for the email, which makes the text easier to read for a general audience.
• Formal for the partner deck, which makes it sound professional.

Fluency makes the fewest changes and suits a light polish of the original. Treat Creative with care: the article says it makes bold changes and may slightly change the meaning, which is the one thing approved copy cannot afford. Custom lets you steer the style with a single word such as "friendly".

Step 5: Rephrase, then read the highlights

Click Paraphrase. Changed words and phrases are highlighted in the right-hand box, and the Rephrase button generates another version as often as you like, per the Paraphraser guide. Read every highlight against the approved source. Look for three things: a frozen term that slipped because of a symbol, a claim that got stronger ("helps" becoming "ensures"), and a number that moved.

Step 6: Check grammar and originality

Run each variant through the Grammar Checker. If any of the source text drew on outside material, run the Plagiarism Checker too: it is Premium only, scans text in more than 100 languages and cites matched passages in APA, Chicago or MLA. For marketing copy the citation styles matter less than the report itself. Freezing terms in step 3 and this plagiarism scan are both Premium only, so the two steps that protect approved copy are exactly the ones Quillbot puts a price on.

Step 7: Export and hand over

Copy the result or use Export to download it. Hand the variants to the person who approved the original, with the source paragraph beside them. Approval of a rewrite is quicker when the reviewer sees both versions side by side.

What Quillbot's help centre warns about

• The Paraphraser is not a detection dodge. The detector article says it is built for clarity, tone and style, not to get past AI detection, and that detectors can flag paraphrased or even human writing.
• Freeze words fail quietly on symbols. Covered in step 3, and the most likely way a product name changes without anyone noticing.
• Creative mode moves meaning. Fine for a brainstorm, wrong for approved claims.

Freeze Words is the feature that makes this job safe, and it sits behind the paywall: that is where the free plan is designed to stop. If your copy has no protected terms, the free modes may be all you need.

How to know it worked

Two measures. First, the review count: how many variants the approver signed off without edits, against how many needed changes. Second, the channel itself: run the reworked ad against the version you would have written by hand, as two variants in the same ad set, and judge both on the measure you chose before launch, such as cost per click or cost per lead.

FAQ

Can I protect product names on the free plan?

Not automatically. Freeze Words is Premium, per the freeze words article; on the free plan, compare every output against your frozen-terms list by hand.

Can an AI agent run this job for me?

Not through Quillbot. Its API article says there is no B2B or B2C API, so the job stays in the app or the extensions.

Can a team share one frozen-terms list?

Team Plans include a team style guide and dictionary, per the Team Plans article, which is the closest thing to a shared list.
