Tone is a real problem, separately from content
Plenty of writing is correct and still wrong. A support article that is accurate but reads like a legal notice. A landing page that says the right things in a voice belonging to a company three times your size. A founder update drafted by someone else that sounds nothing like the founder. In all of those the substance is fine and the register is not.
That is a different job from rewriting for clarity or for length, and doing it by hand is slow because you have to hold the meaning fixed while changing almost every sentence. This workflow does the mechanical part: it keeps the claims and the structure and changes how they sound.
The what changed section is the part worth reading. It explains the moves it made, such as shortening sentences, cutting hedging, replacing abstract nouns with verbs, or dropping jargon. That is more useful than the rewrite itself if you are trying to learn a voice rather than just apply one, because you can make those moves yourself next time.
- Rewritten copy, with the meaning held fixed
- A what changed note explaining the edits
- A variants section when you ask for more than one version
The five presets
Founder voice rewrite is the default and turns corporate copy into something that sounds like a person with an opinion. Brand voice cleanup produces a safe version and a bolder version so you can see the range before committing. Expert tone rewrite raises the authority without tipping into jargon. Beginner-friendly rewrite goes the other way and removes assumed knowledge. Two voice variants gives you a straight pair to choose between.
The variant presets are the more useful ones when you do not yet know what you want. Seeing the same paragraph in two registers side by side makes the decision concrete in a way that describing a tone in the abstract does not.
Whichever preset you start from, the fields stay editable. Describing the voice in your own words, ideally by naming what to avoid as well as what to aim for, produces better results than a preset alone.
Getting a rewrite you can actually use
Be concrete about the voice. Make it friendlier is close to meaningless. Shorter sentences, no jargon, second person, no exclamation marks is an instruction that can be followed. Naming what you do not want matters as much as naming what you do, since the default register of generated text drifts toward enthusiastic marketing copy unless told otherwise.
Give it enough text to establish a pattern. A single sentence has no rhythm to work with, and the rewrite is mostly guesswork. A few paragraphs gives it something to be consistent against. There is room for a substantial amount of source text, though very long input is truncated silently, so lead with the part that matters.
Read the result for meaning drift. Changing how something sounds can quietly change what it claims, and a hedge removed for punchiness turns a careful statement into an absolute one. That is the specific failure mode to check for, especially in anything with legal, medical, or financial content.
- Say what to avoid, not just what to aim for
- Give it a few paragraphs rather than one sentence
- Check that removed hedging did not change a claim
