Writing a long story requires keeping hundreds of details straight. These free, browser-based tools help you audit continuity, plan serial release pacing, build character profiles with temporal state history, and estimate self-publishing royalties. No sign-up required.
A 7-point self-assessment tool evaluating your manuscript draft against the 7 core contradiction failure modes: character limits, timeline logic, item states, knowledge ledgers, world rules, spatial travel and relationship evolution.
Plan your release schedule across Royal Road, Patreon, Scribble Hub or Substack. Calculate required weekly word commitments, drafting hours, Patreon advance margin, buffer runway weeks, and burnout risk index.
Build structured character profiles with dated condition tracking, inventory states, knowledge ledgers, ability limitations and a 3-beat arc. Preserves state changes across chapters instead of overwriting them.
Estimate Amazon KDP earnings before you price your book: Kindle royalties at 35% and 70% with the delivery deduction, paperback royalties after printing costs, and Expanded Distribution, using Amazon.com rates as KDP states them.
While these standalone tools run independently in your browser, Kanonara integrates them into your writing flow. Our Story Doctor continuously inspects chapters as you draft, our Story Bible maintains dated state records automatically, and our fixed A6 bunko layout displays the exact pages your readers turn.
Free during early access. Your writing never depends on an active internet connection.
