Everything it does
A whole studio for the craft.
Write in a real editor, bring in everything you have already written, build the world behind your story, and practice against measurable feedback. The worldbuilding suite, the advanced metrics, and the deep analytics come with Pro.

An editor that fits the form
Fiction, nonfiction, poetry, screenwriting, journalism, copywriting. The editor changes shape for each one: stanzas and line breaks for verse, scene headings and dialogue for a screenplay, and the formatting and metrics it grades against for the rest. It autosaves as you write and keeps a version history with named saves, so a draft is never one keystroke from gone. Pro adds folders to keep a growing backlog in order.
Bring in everything you’ve written
Drop in a single manuscript or a whole backlog and Inkbreaker reads it: Word, ODT, EPUB, PDF, RTF, Markdown, plain text, HTML, spreadsheets, or a zip of all of it at once. A long document splits into chapters on its headings, and you choose where each piece lands. When it finds characters, places, and factions in the text, it offers to file them into a world. Fields it does not recognize are kept with the piece, so nothing is flattened on the way in.
Write from anywhere
The editor and your whole notebook work on a phone, a tablet, and a desktop, and stay in sync across them. Draft on the train, revise on the couch, publish at the desk.
Build the world behind the story
World Bible
Every character, place, faction, and event as a structured entry, grouped into a reference your readers can browse. Entity templates keep the fields consistent so the rest of the suite can reason about them.
Relationship Web
See who is connected to whom as a living graph, then record how a bond changes over time. Drag the scrubber and the whole web recomputes to any moment in your world’s history.
Time Weaver
Lay your world’s history on one spine, in whatever calendar you keep. Eras, lifespans, plotlines, and cause-and-effect arcs, with conflicts flagged before a reader finds them.
Lexicon Engine
Capture how a world’s names sound as reusable profiles, then generate new ones that fit its languages and cultures. Never the same name twice, and never one you have already used.
Consistency Sentinel
A second read that checks your draft against the bible and reports the slips: name drift, contradicted facts, timeline mistakes, point-of-view wobble, and tense shifts.
The whole suite, right in the editor
Open any of these tools as a panel beside your draft. Pull a character’s entry while you write a scene, check a date, or run the Sentinel, without losing your place. One source of truth, no tab-switching.
Practice and measure
Exercises matched to a skill
A library of exercises, each tagged to a writing skill and grouped by writing type, with difficulty that ranges from beginner to experienced. Pick a prompt, write, and submit. Some are micro exercises built for a focused five minutes, with a word counter and a soft timer; others are a long sitting. Free accounts get three a day. Pro opens the full library, lifts the daily cap, and keeps every submission in your history.
A prose engine, not an opinion
Reading ease, sentence variety, vocabulary range, passive voice, pacing, imagery, tone, and dialogue, computed straight from your text. Paste the same passage twice and the numbers match to the decimal. No AI, no model, no judgement: the same input always returns the same reading, so you can act on it and check whether the next draft actually moved.
Nine advanced readings, with Pro
Pro turns on a deeper layer the engine keeps quiet on free accounts: emotional valence and arousal, lexical cohesion and transition flow, sentence-complexity and subordination patterns, and a syntactic-variety read on how repetitive your structure runs. It keeps the history too, so each metric carries a trend across your recent drafts instead of a single number in isolation.
Skill focus and your Report Card
Choose a skill to develop for each writing type, or take the one Inkbreaker recommends from how you have been writing. Every exercise you finish feeds XP into that skill, and skills level from apprentice up to master. The Report Card gathers all of it: progression, streaks, writing volume, and your strengths and weak spots per type. Pro adds the trend charts and the integrity signals that show what is improving and what has stalled.
Share and play
Trade reads with the community
Request a read and we match your piece with writers whose focus fits it. Every read you receive and every read you give lands in one history. Reading closely is how you sharpen your own eye, so giving counts as much as getting.
Exquisite Corpse, built in
A writing game for the whole community. One writer opens, the next adds a line seeing only what came just before, and the finished chain is revealed to everyone. Low stakes, real surprise.
Keep it all together
It all lives in your notebook
Drafts, published pieces, folders, series, and worlds, all in one notebook. Organize a growing backlog with a full-screen file manager that moves pieces in bulk. Collect related pieces into a series, and on Pro, watch its audience: who is reading, which parts land, and how your following grows.
