Character Bible

Frequently asked questions

Everything you need to know about generating consistent character reference images.

What is Character Bible?

Character Bible is an AI tool that generates a consistent set of multi-angle, multi-expression reference images for a character from a single photo — so the same face shows up in every image. It's built for VTubers, virtual influencers, webtoon/comic artists, indie game developers, and brand mascot teams.

How does it work?

Upload one to three photos of your character, and Character Bible generates a full reference set — front, side, and back angles plus a range of expressions — all keeping the same face. You can then generate custom outfits or scenes for that same character.

Do I need to sign up to try it?

No. You can generate one full reference set without creating an account. Log in only when you want to save your results to your library.

What is Face Identity Lock?

Face Identity Lock is how Character Bible keeps every angle and expression anchored to your original photo instead of drifting into a different-looking person. Each generated shot (in the photo-realistic style) is checked against your seed photo for a match score, shown right on the image — so you can see how closely it matches instead of just taking our word for it.

How does the 360° character preview work?

Once a character is saved, you can generate one extra angle (a 135° back three-quarter shot, 1 credit) and Character Bible builds an 8-position turntable from it — drag with your mouse or swipe with your finger to spin the character around. The other angles are mirrored from shots you already generated, so it only costs that one extra credit.

What counts as a credit?

1 credit = 1 generated image. A full reference set (4 angles + 4 expressions) costs 8 credits. Adding a custom outfit or scene costs 1 credit.

Do unused credits roll over?

No — credits reset to your plan's monthly allowance at the start of each billing period.

Can I cancel my subscription anytime?

Yes. Manage or cancel your subscription anytime from your account page — you'll keep Pro access until the end of your current billing period.

Can I use the generated images commercially?

Yes. Subject to our Terms of Service, you own the right to use images generated with the Service for personal or commercial purposes.

Will you sell or use my photos for advertising?

No. We never sell your personal information or uploaded photos to third parties, and we never use them for advertising. See our Privacy Policy for full details on how your data is handled.

What image formats and sizes are supported?

Upload JPG or PNG photos — up to 3 per character — and we compress them automatically. You can generate output in square, portrait (9:16), or landscape (16:9) aspect ratios.

What's the difference between a character bible and a character sheet?

A character sheet (or model sheet) is the exported image — your character's angles and expressions composited into one downloadable file. A character bible is the fuller profile behind it: the same visual reference set plus a written personality and backstory, saved together in your library. Character Bible generates both — the sheet is one output of the bible.

Can I export a PDF?

Not currently — the character sheet exports as a single PNG image via the "Download model sheet" button, not a PDF.

Does Character Bible work for AI video, not just images?

Not yet. Character Bible currently generates still reference images only — angles, expressions, and custom outfits or scenes. Keeping a character's face consistent across AI-generated video isn't supported today.

What's the difference between the turnaround and the model sheet?

The turnaround is the set of angle shots — front, 3/4, side, and back — that let you see a character from every side. The model sheet is the exported file: those angles plus your expression shots, composited into one downloadable reference image.

Can I organize my characters with tags, or just search by name?

Search by name is supported in your library today. Tagging or categorizing characters isn't available yet.
