Common rephrase mistakes & quick fixes

The 8 failures we see most, and how to fix each in under 10 seconds.

Meaning drift, output says something different

Fix: Technical terms got swapped. Paste them back in and re-run. Or switch intent to "Clearer" which is more conservative than "Simpler".

Output is nearly identical to input

Fix: Change intent or tone. If your input is already polished, the model has nothing to fix. Try "More engaging" or "Shorter".

Tone overcorrected, formal became stilted

Fix: Avoid stacking intents with tones. "Formal" + "Academic" reads as stiff. Use one strong signal at a time.

Industry jargon stripped out

Fix: Add a note like "keep technical terms: X, Y, Z" to your input. Or switch intent from "Simpler" to "Clearer".

Passive voice persists

Fix: Set intent to "More engaging", it explicitly targets active voice. Combine with "Authoritative" tone for best effect.

Output is grammatically wrong

Fix: Rare, but happens on very short or poorly punctuated inputs. Punctuate the input and add a trailing period.

Academic voice lost

Fix: Use "Academic" tone AND "Clearer" intent. Without "Academic" tone, the AI defaults to conversational voice.

Output changed numbers or facts

Fix: The model should preserve numbers but can paraphrase around them. Double-check any statistic, date, or dollar figure in the output.

Frequently asked questions

Every question users ask before running their first rephrase.

It rewrites your text at roughly the same length while preserving meaning. Pick an intent (clearer, simpler, etc.) and a tone, and the output shifts wording, sentence structure, and voice without padding or trimming substance.
Yes. The model is prompted to maintain semantic equivalence. In our internal tests (n=600 paragraphs across 6 domains), meaning-preservation rated 4.6/5 by human reviewers. If a sentence relies on a technical term, keep that term in the input so the AI knows not to swap it.
Legally and for Google's duplicate-content filters, yes. Outputs are statistically distinct from inputs. For academic plagiarism checkers (Turnitin, iThenticate), rephrasing lowers scores but doesn't always zero them out. Always cite original sources.
No, and we don't recommend trying. The rephraser is designed to improve your writing, not disguise AI origin. Some AI detectors may still flag output. Be upfront about AI assistance when institutions require it.
Rephrasing keeps length roughly constant and swaps wording. Expanding adds substantial new detail and grows length 2-3x. Use rephrase when you want a polished version of your point; expand when your point is too brief.
Input is capped at ~600 words per run. For longer content, split into sections. Rephrasing one paragraph at a time gives better tonal consistency than batching.
Yes, noticeably. "Formal" vs "Casual" produces ~40% different word choice on the same input. "Empathetic" shifts from directive language ("you must") to supportive ("you might consider").
Yes, for major languages. Spanish, French, German, Italian, Portuguese, Dutch, Hindi, and more. Put the input in the target language; the output matches. Mixed-language inputs produce inconsistent results.
No. Text is processed in memory, returned, and discarded. Nothing is logged or used for model training.
When an input is already well-written at the requested tone, the model has little room to move, it changes structure rather than vocabulary. Try a different intent or tone to see bigger shifts.
Yes, but quality degrades after the 3rd pass, the text drifts from original meaning. One or two passes max for best results.
Google's March 2026 spam policy targets scaled, low-effort content, not thoughtful rephrasing. A rephrased sentence that preserves expertise, adds clarity, and is published on a real site is fine. Mass-rephrased doorway pages are not.
