Plot templates by trope
Original Japanese tools
Japanese originals: The two tools below the generators are BunCho's original Japanese pages. They write in Japanese and are handy for translators and learners.
AI title generator
Enter a genre and a few keywords, and the AI proposes title ideas for a novel, manga or video. It's tuned on Japanese web fiction, so it is especially good at the long, descriptive titles common in light novels and isekai.
How to use it
- Choose a genre.
- Type a few keywords in Japanese (for example 婚約破棄 for "broken engagement" or 辺境 for "frontier").
- Generate, then keep the titles you like and run again for more.
Tips
- Mix one rising trope from our weekly trend report with one unexpected word.
- Translators and learners can use it to see how Japanese titles are typically built.
- Generate several rounds and combine halves of different titles.
AI synopsis generator
Give it keywords or a title and the AI drafts a synopsis — the short pitch readers see before they click. You can then keep writing the story together with the AI in the relay novel tool.
How to use it
- Enter keywords or your working title in Japanese.
- Generate a synopsis.
- Edit it by hand, or continue the story in the AI relay novel.
Tips
- Use the synopsis as a test: if it sounds generic, your premise may need a sharper hook.
- Try the same keywords with a different genre to explore tones.
Questions
- Are the tools really free?
- Yes. All the generators on this page are free, with a daily limit so they stay free for everyone. The long-form BunCho Studio is a paid plan with a 7-day free trial.
- Do they write in English?
- Yes. The four generators at the top write in English. The two original Japanese tools further down write in Japanese, which is handy for translators and learners.
- Who owns what I generate?
- You are free to use what you generate in your own work. Please check the Terms of Use (in Japanese) for details.
