Built for Creators Who
Refuse to Forget

MangaCreator OS was born from a frustration shared by countless manga artists and writers: the more complex your story gets, the harder it becomes to keep every detail consistent. Characters change eye color between chapters, timelines contradict, relationships shift without explanation.

We built a system that thinks like an editor, a story analyst, and a database all at once — giving independent creators the same story management tools that major studios use, without the cost or complexity.

MangaCreator OS is independent, creator-first, and committed to remaining accessible to every storyteller — from first-time doujinshi artists to professional serialized mangaka.

Frequently Asked

Is MangaCreator OS really free? +
Yes — the core features are permanently free. Character management, timeline, relationships, AI consistency check, and bible generation are all included at no cost. Advanced features like cloud sync and collaboration will be available in a future Pro tier.
Where is my data stored? +
All your data is stored locally in your browser using localStorage. Nothing is sent to any server. Your story data is 100% private and stays on your device. This means clearing browser data will remove your projects — export regularly as a backup.
How does the AI Consistency Check work? +
The current version compares your scene text against your character names, checks if your timeline has sufficient scenes for story progression, and validates relationship consistency. The upcoming AI upgrade (Jul 2026) will add deep natural language analysis powered by Claude API for much more sophisticated checks.
Can I use this for light novels or webtoons, not just manga? +
Absolutely. While designed with manga in mind, MangaCreator OS works equally well for light novels, webtoons, visual novels, and any long-form serialized storytelling format that requires consistency tracking.
Will there be a mobile app? +
Yes — mobile apps for iOS and Android are planned for Q1 2027 on our roadmap. In the meantime, the web app is mobile-responsive and works in your phone browser.
