# Inkbreaker

> Inkbreaker is a full writing platform for the craft of writing. Writers draft and publish in a real editor, build a body of work, and grow within a community of working writers. Deliberate practice is built in: writers run targeted exercises, receive deterministic metrics on their prose (readability, sentence variety, passive voice, dialogue ratio, adverb density, vocabulary, and more), and can trade honest feedback with other working writers. Every piece of creative writing on the platform is human-written. Prose analysis is fully deterministic; each metric is computed by a transparent algorithm, not a language model. The only place AI touches the platform is content moderation, where it is used to flag unsafe submissions. Inkbreaker does not generate prose, does not offer AI feedback, and does not accept AI-generated submissions.

Inkbreaker is built by Spiffai LLC. It is a place to write, publish, and grow a readership, and it treats craft improvement the way athletes and musicians treat practice: measurable, repeatable, and improvable.

## Guides

- [Lexical Density: How Much Information Is Your Prose Carrying?](https://inkbreaker.com/guides/lexical-density): Lexical density measures the ratio of content words to total words. It is one of the best signals for whether your prose is working hard or coasting.
- [Vocabulary Range: What Your Word Choices Reveal About Your Prose](https://inkbreaker.com/guides/type-token-ratio): The type-token ratio is a simple fraction with a lot to say. High vocabulary range signals freshness. Low range signals repetition. Here is how to read yours.
- [Sentence Variety: The Fastest Fix for Flat Prose](https://inkbreaker.com/guides/sentence-variety): Why sentence variety matters, how to measure it, and a ten minute practice loop you can run on any draft.
- [Dialogue Ratio: How Much Talking Is Too Much?](https://inkbreaker.com/guides/dialogue-ratio): Dialogue makes scenes fast. Narration makes them dense. The ratio between them is one of the strongest pacing levers you have.
- [Reading Ease Is Not Dumbing Down: What the Flesch Formula Measures](https://inkbreaker.com/guides/reading-ease-not-dumbing-down): The Flesch Reading Ease score is the most misunderstood metric in prose analysis. Here is the formula, the inputs, and what the score actually says.
- [Adverb Density: The Quiet Signal That You Are Telling, Not Showing](https://inkbreaker.com/guides/adverb-density): Adverbs are not a sin. But a high adverb count almost always points to weak verbs and scenes where the writer is explaining instead of showing.
- [The Passive Voice Audit: How the Engine Finds It and Why It Matters](https://inkbreaker.com/guides/passive-voice-audit): Passive voice is not a crime. It is a structural choice with specific costs and uses. Here is how Inkbreaker detects it and what the percentage means.
- [Scale, Scope, and the Art of Knowing When to Stop](https://inkbreaker.com/guides/worldbuilding-scale-and-scope): The depth of a world should be proportional to its narrative purpose. The world does not have to be finished. It has to be finished enough.
- [Register and Distance: Why Worldbuilding Has So Many Voices](https://inkbreaker.com/guides/worldbuilding-register-and-distance): A proclamation does not sound like a field journal. The documents a culture produces reveal as much about it as the documents’ content does.
- [Why Your World Needs a Vocabulary: The Science of Proper Noun Density](https://inkbreaker.com/guides/proper-noun-density-worldbuilding): A name is a claim that the thing is real. Here is the measurable difference between a world that feels inhabited and a world that feels sketched.
- [Exposition Economy: What Jemisin Knows That Most Worldbuilders Do Not](https://inkbreaker.com/guides/exposition-economy-jemisin): Three Hugos in a row, almost no direct exposition. The Broken Earth trilogy is a working seminar in how to deliver world information without stopping the story.
- [Le Guin’s Anthropology: Why Worldbuilding Is Culture, Not Geography](https://inkbreaker.com/guides/le-guin-anthropology-worldbuilding): Le Guin trained as an anthropologist before she became a novelist. The method she brought to fiction is the one that lets a culture feel derived rather than invented.
- [The Internal Consistency Problem: Why Fictional Worlds Need Rules](https://inkbreaker.com/guides/internal-consistency): A fictional world is consistent only to the degree its writer makes it so. Sanderson’s First Law and the deeper craft of rule-governed thinking.
- [What Worldbuilding Actually Is: A Discipline, Not a Hobby](https://inkbreaker.com/guides/what-worldbuilding-actually-is): Tolkien called it sub-creation. The test is not entertainment but secondary belief. Here is what that means in practice, and why it can be measured.
- [The Math of Rhythm: What Sentence Length Variation Actually Measures](https://inkbreaker.com/guides/math-of-rhythm): Rhythm in prose is not a feeling. It is a pattern of durations. Here is the formula behind sentence length variation and how to use it.
- [Passive Voice: When It Works and When It Drains Your Prose](https://inkbreaker.com/guides/passive-voice): Passive voice is not the villain writing teachers make it out to be. But it does have a cost, and knowing your percentage is the first step to using it on purpose.
- [Readability Scores: What Flesch and Grade Level Actually Tell You](https://inkbreaker.com/guides/readability): Flesch Reading Ease and Flesch-Kincaid Grade Level are the two numbers everyone cites and almost no one explains. Here is what they measure, what to aim for, and when to ignore them.
