A prose analysis tool that reads your habits, not your grammar
Ten craft lenses colour your adverbs, filter words, rhythm, and echoes right on the page — teaching from both sides, so you decide what to keep. It never rewrites a word.
The Adverbs and Filter-word lenses wash your habits onto the page itself — a mirror, not an editor.
Most “prose analysis” tools grade you. They score your readability, flag your passive voice as an error, and hand back a report card in a separate dashboard — as if there were one correct way to write a sentence, and your job was to hit it.
Fiction doesn’t work that way. A long sentence can be monotony or momentum. An adverb can be a crutch or exactly the right beat. The passive voice is sometimes the whole point. What a novelist needs isn’t a grade — it’s to see the pattern and make the call.
Calliope’s craft lenses are that: ten reading passes that colour your own habits onto the page, and teach each one from both sides.
What the lenses show
Turn one on and the wash appears on the manuscript itself — the analysis is the page, not a panel to the side:
- Adverbs and intensifiers — the -ly words and the very / really / just you lean on.
- Filter words — saw, felt, heard, knew — the perception verbs that hold a reader at arm’s length.
- Sentence rhythm — every sentence tinted by length, so a block of one colour shows monotony creeping in.
- Sensory balance — which senses a scene actually uses, so an all-visual page reveals itself.
- Echoes — a word and its nearby repeats, flared together, so an unintended echo jumps out.
- Plus to-be and passive constructions, said-bookisms, and repeated openers.
Hover any lit word for the why; click it for a calm sidebar that argues the case for the habit and the case against it, with every occurrence in the chapter. There’s no score, and no “fix this.”
It shows; it never rewrites
This is the whole stance. A lens recolours prose you already wrote — it never changes a word, never suggests a replacement, never drafts the line for you. Turn it off and the page is exactly as you left it. Where a tool like ProWritingAid hands you a report and a rewrite, Calliope hands you a clearer view of your own writing and trusts you to revise it.
Where it lives
The lenses are part of a calm, distraction-free editor built for whole books — the same place that holds your canon and your writing stats. They cost nothing and need no account: they run on your own text, right there on the page. See the craft-lenses guide for the full set.
That’s the promise, here as everywhere in Calliope: it helps you see your writing clearly. It never writes it for you.
The writing is yours. Keep it that way.
