🎉 New feature just dropped: Custom Details for your characters!

You already fill in the big stuff — appearance, motivation, backstory, arc. But there's always that one detail that makes a character feel real and doesn't fit any box. Now it has a home. 🏡

You can add as many extra pieces of info as you want. Each one has three simple parts:

① Type (pick from a dropdown)

② Label (a short name to keep you organized)

③ Detail (the actual info)

The magic is in the Type, because it tells BookNova how to use each detail. There are three:

🔹 Trait — an always-true fact, treated as canon across the whole book.

👉 e.g. "Handedness → Left-handed" or "Distinguishing mark → A faded scar over her right eye"

🔹 Note — your catch-all for anything else: lore, quirks, secrets, history.

👉 e.g. "Fear → Secretly terrified of the ocean" or "Backstory → Raised by smugglers, distrusts anyone in uniform"

🔹 Mannerism — a recurring behavior tied to a trigger. This is the one I'm proudest of. 👇

👉 e.g. "Spell tell → Lets her hair down right before releasing a powerful spell"

Here's why Mannerisms are special. Anyone can tell an AI "this character does X." The hard part is getting it to do X only when the moment actually calls for it — not stamping it into every chapter, and not describing it the same way each time (a dead giveaway a machine wrote it).

So BookNova handles them differently under the hood: it weaves a mannerism in only when the trigger genuinely happens in a chapter, and rewrites it fresh every time. Your mage lets her hair down when she's about to unleash something powerful — a real, earned signature moment your readers start to anticipate — instead of a tic on every page. That's the difference between a character that feels written and one that feels alive. ✨

Best part? It lives right on the character, so it carries across every book you use them in. Build once, and every trait, quirk, and signature move follows them everywhere. 📚

Go try it and tell me what you put in — I already know some of you are going to build some wonderfully weird characters, and I'm here for it. 😄

Happy writing,

The BookNova Team
