# Text Rhythm. The Cadence Visualizer

**Text Rhythm** is a zero-friction, in-browser prose analyzer that shows you the *shape* of your writing. Paste any text and instantly see how your sentences flow, their lengths, rhythms, and readability, without signing up, uploading anything, or sending a single character to a server.

## What It Does

Most writers know when something "reads slowly" or "feels choppy" but can't pinpoint why. Text Rhythm makes the invisible visible: sentence length becomes a bar chart, cadence becomes a waveform, and density becomes a heatmap.

## Five Views

**Sentences.** a live editable view. Write or paste directly. Sentences are highlighted as you move your cursor so you always know which one you're in.

**Paragraphs.** a bird's-eye view of your document by paragraph, showing how structure shifts across sections.

**Shortest.** surfaces your snappiest lines. Useful for finding punchy anchors to use as pull quotes or transitions.

**Longest.** flags runaway sentences that may be dragging reading pace.

**Heatmap.** every sentence is colored by length: green for short, neutral for medium, amber for long, red for anything that runs too far. Scan the whole document in one glance.

## The Rhythm Graph

The signature feature: a silhouette graph where each bar represents one sentence and its height is the word count. Monotone bars signal repetitive rhythm. A varied silhouette signals dynamic writing. Gaps between clusters show where your breathing points land.

## Stats Bar

Every keystroke updates the stats bar at the top: total words, sentence count, paragraph count, average sentence length, estimated reading time, and Flesch-Kincaid readability score.

## Focus Mode

Typewriter-style focus mode dims everything except the sentence under your cursor. Useful for reviewing one thought at a time without distractions.

## Three Themes

Dark, Paper, and Forest, because the right visual context matters for writing.

## Privacy

Your text never leaves your browser. Nothing is sent to any server. The editor persists your draft in `localStorage` so it's there when you come back. Clearing the editor is undoable (10-level undo stack, plus `Ctrl+Z` after Clear restores it).

## Who It's For

Writers, technical communicators, content marketers, and editors who care about sentence-level rhythm rather than word count. Especially useful when editing long-form blog posts, essays, or documentation where monotony creeps in.
