He stopped. The air felt entirely wrong. She turned slowly and scanned the dark edge of the treeline. In the late summer of that year we lived in a house in a village that looked across the river and the plain to the mountains.

Rhythm Chart

Your entire document's pace visualized as an instant bar chart. Noticed a run of long sentences? A cluster of shorts? Click any bar to jump directly to that sentence.

See the overall shape of your prose at a bird's-eye view — essential for revision.

Phrase by Phrase

Soft Breaking

Insert line breaks inside sentences to view them one phrase, one chunk at a time. Toggle the mode off and the breaks vanish — your original text stays completely untouched.

Study the masters. Break a Hemingway sentence into its beats to understand exactly how it breathes, then build your own style from what you discover.

Musical Prose

Syllable Count

See the syllable count for every phrase or sentence. Invaluable for poetry — and equally powerful in prose. Combined with Soft Breaking, compose sentences that flow like music.

A phrase of 4 syllables is naturally complemented by one of 3 or 5. Try it — you'll hear the difference immediately.

Word Awareness

Repetition Checker

Surface repeated words with an adjustable Levenshtein distance slider — catch near-duplicates, variants, and inflections you'd miss on a re-read.

Track pronoun density separately for a cleaner, more varied narrative voice.

Adverbs & Passive Voice

Instantly see adverbs and passive constructions highlighted in your prose. The classic advice of Strunk, White, and King — made visual and interactive.

Decide what stays and what goes with full context, not guesswork.

Phonics & Prosody

Discover alliteration, consonance, and rhythmic sound clusters hidden in your writing. Highlight by repeating letters, or switch to homophonic mode for deeper sonic analysis.
