Freeze Keywords: keep specific words unchanged

James
Updated

Quick answer: Add a word or phrase to the Freeze keywords panel before running the humanizer, and it stays exactly as written in the output.

What freeze keywords do

Freeze keywords tell the humanizer: do not touch this. Common cases:

  • Proper nouns — names of people, products, companies, places.
  • Technical terms — domain-specific vocabulary that has no good synonym.
  • Brand names — when you do not want the rewrite to swap them.
  • Citations and references — names you have to preserve verbatim.

Add a freeze keyword in 2 steps

  1. Open the Humanizer.
  2. Click Freeze keywords (usually next to the input panel). Type the word or phrase and press Add.

Add as many as you need before clicking Humanize.

Freeze keywords panel open over the humanizer, with three keywords already added as pills — "GPTinf", "non-native", "summaries" — and a warning that the recommended maximum is 3.

Note: Free anonymous users can freeze up to 3 keywords. Registered free users and all paid plans get unlimited freeze keywords.

Humanized output with the three frozen terms — "GPTinf", "non-native", "summaries" — highlighted in purple and reproduced verbatim throughout the rewrite, while the rest of the text shows the green "changed" highlight.

What gets frozen, exactly

  • Exact spelling and casing. Case matters — "GPTinf" and "gptinf" are different entries.
  • Single words or multi-word phrases. Both work.
  • Plural and singular are separate. Freeze "datasets" and "dataset" if both appear.

Use cases that work well

  • A research paper that mentions "Heteroskedasticity-consistent standard errors" — freeze the whole phrase so the rewrite leaves it intact.
  • A product spec mentioning "Postgres 15," "Redis," "Kafka" — freeze each one.
  • An essay quoting a specific author — freeze the author's name.

Use cases that do not help

  • Common words. Freezing "the," "and," or "of" does not change the output noticeably.
  • Whole sentences. Freeze keywords are for words and short phrases. To preserve a whole sentence, use Selective Rephrase on the other sentences instead.
  • AI-prone phrases. Freezing "in conclusion" or "it is important to note" defeats the point — you would want the humanizer to rewrite those.

FAQ

How many freeze keywords can I add? Free anonymous: up to 3. Registered free and all paid plans: unlimited.

Does freeze work with file uploads? Yes. Add the freeze keywords before clicking Humanize, then upload the file.

What if my frozen term still got changed? Check case and spelling — both must match exactly. If they do, contact support with a screenshot.
