Your writer's desk.

Inkbreaker is a full writing platform for writers who care about the work, at any level. Write and publish in a real editor, build a body of work, and trade honest feedback with other working writers. When you want to drill a specific skill, targeted exercises and objective prose metrics are there too.

Both. The editor is a full writing environment. You can draft anything here, not just exercise submissions. The notebook keeps your work in progress organized. Exercises are structured practice sessions that open in the same editor. Your drafts and submissions all live in the same place. The ritual is yours to define.

Yes, and we measure it rather than promise it. We test the editor against a 200,000 word manuscript, 5,000 paragraphs kept in a single piece. Typing into the middle of it costs the editor about 2 milliseconds of work per keystroke, with no dropped frames. A short story costs about 0.7. So a book that is fifty times longer asks about three times as much per key, and both are a small fraction of a single frame of a 60Hz screen. (Measured on a production build; an older machine will be slower.) You can split a book into chapters if that is how you think, and folders will hold them like a binder. But you do not have to.

No. Prose analysis on Inkbreaker is fully deterministic. Every metric, readability, sentence variety, passive voice, dialogue ratio, adverb density, vocabulary, is computed by a transparent algorithm, not a language model. There is no AI anywhere in the product; even content moderation is a deterministic, rule-based filter plus human review, not AI. Every story, exercise, and comment is written by a human. We do not accept AI-generated submissions.

No. Poetry is handled as a separate category with its own benchmark set. Sentence-based metrics like average sentence length, sentence length variation, and paragraph rhythm are suppressed entirely for verse. Line breaks, fragments, and unconventional punctuation are not flagged. What the grader does measure for poetry is vocabulary range, lexical density, and adverb density, which apply to verse as much as prose. Intentional repetition for anaphora or refrain is not penalized. The repetition threshold for poetry is set significantly higher than for prose types.

Format-aware. Screenwriting has its own benchmark set built around the conventions of the medium. The passive voice benchmark is set at 40 percent. Action lines are conventionally passive and penalizing them would produce noise rather than signal. Reading ease targets 80, higher than fiction, because action lines should be instantly visualizable. The grader measures scene economy, visual specificity, and sentence variety calibrated for the format. It does not apply prose standards to a visual medium.

No. Every writing type has its own benchmark set. Technical writing tolerates up to 20 percent passive voice and high repetition because consistent terminology matters more than variety. Copywriting has the strictest reading ease requirement on the platform because every word has to earn its place. Poetry suppresses sentence-based metrics entirely. Journalism tolerates more passive voice than fiction for attribution reasons. When you select a writing type before grading, you are choosing which benchmark set your passage is measured against. The same passage graded as Fiction and as Technical Writing will produce different ratings. The scores do not change. The targets do.

The full platform is free with no time limit. Exercises, metrics, XP, skill progression, leaderboards, publishing, community, peer feedback, series, folders, version history, live writing sprints, and draft import and export are all included at no cost. Pro adds metric history and trend analysis across all your submissions, unlimited daily exercises and prose-engine grading, the nine advanced metric readings, advanced writing modes tuned for specific genres, the worldbuilding and language tools, and community audience analytics. Pro is $12 a month or $99 a year, about $8.25 a month billed annually. All new accounts get a free 7-day Pro trial. No credit card required.

Free accounts can submit three exercises a day. The count resets at midnight in your time zone. Pro is unlimited.

Feedback requests go into a queue. We match you automatically with writers whose skill focus and XP in your genre fit your piece, and we fan each request out to several of them at once so you are not waiting on one person. If nobody delivers, the queue keeps trying for up to two weeks and pulls in a moderator near the end as a backstop. You rate the feedback when it arrives. That rating shapes future matches. The system is designed to produce responses, not hope for them.

Feedback requests go into a queue. We match you with writers based on their skill focus and XP in your genre, not whoever happens to be free, and we keep trying for up to two weeks so a piece is never left waiting. You rate the feedback on two criteria when it arrives: whether it was specific to your piece, and whether it helped you see something you'd missed. Those ratings build each reviewer's feedback score, which shapes who gets matched next. Writers with consistently high scores earn a Trusted Reader marker on their profile.

You own everything you write here, full stop. You decide who can find it and who can read it. Any piece can be public, unlisted so it opens only by direct link and stays out of search engines, or a private draft you share with a secret, revocable link. You can keep your profile out of search or make it private, set the rights notice shown under each piece, and turn on reader protection that discourages casual copying and credits anything a reader copies. If you ever need to prove authorship, you can download tamper-evident evidence for any piece (creation date, content fingerprint, edit history). And if someone posts your work here, you can file a DMCA takedown from our support page. We are honest about the limits: nothing on the web can stop a screenshot, so these tools raise friction and make a stolen excerpt traceable rather than promising the impossible. All of it is free.

Writers at any level who want a real place to write every day. That means somewhere to draft, run targeted exercises, get honest metrics, request feedback from skilled readers, and publish to a community that cares about the craft. Fiction, nonfiction, poetry, screenwriting, journalism, and blogging all have dedicated exercises, genre-aware grading, and specialized editor formatting. Beginners start with structured prompts and clear targets. Working writers use the editor and metrics as part of their daily ritual. Both are the point.
