The measurements, itemised
Word count, average sentence length, how much that length varies, adverbs per thousand words, estimated passive voice, share of dialogue, filter words, and reading grade.
Clarity checking that shows its working
A clarity checker that gives you numbers, not opinions
Sentence length and how much it varies, passive voice, adverb density, filter words, repetition, reading grade. All of it counted in code. Run it twice on the same page and you get the same answer twice.

Chapter 1
Lantern Road
BIH2Paige ready
Mara paused at the old bridge, one hand on the map case, listening for the bell that only rang when someone crossed from the wrong side of the city.
Behind her, Tomas kept his voice low. "If the archive is awake, it already knows we are here."
The lanterns along the canal flickered blue. That meant memory magic, or rain, or a warning left by someone who wanted them alive for one more chapter.
Paige suggestion
Add one concrete cost for using the map before the next scene begins.
Stable between runs
The same passage returns the same numbers every time.
Style stays yours
Fragments and dialect read as deliberate choices.
Nothing moves on its own
Every change waits for you to accept it.
Built for fiction workflow, not generic text output
Most clarity tools hand you a single score and leave you to guess what produced it. This shows the measurements underneath. How long your sentences run, how much they vary, how often the passive turns up, which words you lean on. You see the specific habit making a passage hard to follow, then decide whether it is a problem or the effect you were after.
Repetition you stopped hearing
Words echoing close together, sentences in a row opening the same way, and the phrases you reach for without noticing.
Fix a passage, not the file
Highlight the sentence that reads badly and tighten it, simplify the jargon, or vary the rhythm. The rest of the page stays put.
Chapter or whole manuscript
Check the page in front of you, or run it across every chapter to find the recurring habit rather than the one-off.
How to use it
Start small, choose a direction, then let the workspace carry context into the draft.

Read the measurements
The numbers sit beside the text. Long stretches of uniform sentence length, heavy passive, or a word you have used forty times all show up as figures you can check.
3
Change only what you want changed
Suggestions arrive one at a time and you accept or reject each one. Deliberate repetition survives, because you are the one deciding.
Prompts to try
“Which paragraphs in this chapter are hardest to follow?”
“Tighten this sentence without losing the rhythm.”
“Simplify the jargon in this section.”
Frequently asked questions
What does a clarity checker actually measure?+
Here it measures sentence length and how much that length varies, adverb density per thousand words, an estimate of how much of the text sits in passive voice, the share of words inside dialogue, filter words, and a Flesch-Kincaid reading grade. Those are counted in code, so the same text always produces the same figures.
Is the score generated by AI?+
No. The measurements are arithmetic, which is what keeps them stable between runs and comparable between drafts. AI comes in separately, when you ask for a rewrite of something you have already decided to change.
Will it flatten my style?+
It corrects nothing by itself. A long sentence is not automatically wrong and a fragment is not an error. Both show up as measurements for you to read. Nothing is applied until you accept it.
Does it work on a whole document or just a page?+
Both. You can check the passage on screen, or run across every chapter to see which habits repeat throughout rather than in one scene. Whole-manuscript runs are a paid feature.
Can it check writing that is not fiction?+
Yes. The same measurements apply to any prose. Brand and marketing documents get an additional read that looks at reading grade, buzzwords, superlatives, and whether a call to action is present.
Is it free?+
The measurements are free, and free accounts also get a set of quick fixes and one chapter edit pass each day. Paid plans raise those limits and add the whole-manuscript runs.
