Why does my AI character keep changing?

AI tools invent any detail you don't specify, and invent it differently each time. A complete card pasted into every prompt fixes most drift.

How is the score calculated?

Six fields carry set points. One or two words earns half, three or more descriptive words earns full points.

What score should I aim for?

90 or above before generating a series.

What is a signature prop?

One recurring item — a watch, scarf, bag — that makes the character recognisable in every scene.

Can I save my character?

Copy the card into the AI Video Prompt Builder, which saves characters in your browser and supports export/import.

Face: Describe face shape, eye colour and one distinct feature (mole, dimples, glasses).
Hair: Add length, texture, colour and style — AI tools change hair more than anything else.
Outfit: Name every visible item top to bottom, with colours.
Colour palette: List 2–3 signature colours and repeat them in every prompt.
Voice: Give pitch, pace, language and accent so dialogue sounds the same each scene.
Signature prop: One recurring prop makes a character instantly recognisable.

About Character Consistency Checker

The number one complaint from AI story creators is that the character looks different in every clip. That happens because AI video tools fill in any detail you leave out — and they fill it differently each time. The fix is a complete, specific character card that you paste into every single scene prompt, word for word.

This checker scores your card out of 100 across six areas that matter most for visual and audio consistency: face, hair, outfit, colour palette, voice and a signature prop. A field with just one or two words earns half points, because "blue shirt" still leaves too much to chance; three or more descriptive words earns full points.

Aim for 90 or above before you start generating. Colours are especially powerful — repeating the same two or three named colours in every prompt keeps the look stable even when lighting and camera angles change. A signature prop, such as a brass watch or a red dupatta, gives viewers an instant visual anchor across episodes.

When your card is complete, copy it into the character section of our AI Video Prompt Builder, where it can be saved in your browser and exported as a file for backup.

The checker runs entirely in your browser. Nothing you type is uploaded or stored.

Examples

“Face: round” scores half; “Face: round face, big brown eyes, small mole on left cheek” scores full.
Adding a signature prop like a red scarf takes most cards from Good to Excellent.
