Manuscript Lint BETA

Automated prose analysis for writers — free, private, no signup

Zero network requests. Your manuscript never leaves this device.

This tool is entirely self-contained. Every word-count, every regex, every analysis runs in JavaScript inside your browser. There are no servers, no APIs, no database calls, no analytics on your text. Your manuscript is never transmitted anywhere — not even for a millisecond.

What you'll get

1

Structure & Pacing

Chapter word counts, scene counts, paragraph density, and a visual heatmap showing where your pacing runs dense or punchy.

2

Overworked Pattern Detection

40+ phrase patterns pulled from real editing guides. Catches "a [adjective] thing," textile metaphors, definition-by-negation, redundant attribution, over-explanation, stock pain language, and more.

3

Word & Phrase Frequency

Top words, bigrams, trigrams, crutch words (just, very, suddenly), sensory filter verbs (she felt, he noticed), and adverb density.

4

Repetition Proximity

Flags when the same distinctive word appears twice within a page — the kind of echo readers actually catch.

5

Dialogue Analysis

Dialogue-to-prose ratio per chapter, tag audit (how often you use "said" vs. fancy alternatives), and balance checks.

6

Custom Word Lists

Add your own overused words and phrases. They get flagged alongside the built-in checks and saved between sessions.
