Consistent Character Prompt Lock

A character prompt lock is a fixed set of descriptors — face, hair, build, clothing, signature items, and style parameters — that you reuse in every image generation. Because AI image generators have no memory between generations, repeating the same anchor description is the main way to keep a character recognizable across different scenes.

You describe your character once, and the tool turns that description into a complete consistency framework: a visual anchor prompt to include in every generation, structured physical and clothing descriptors, platform-specific prompts, seed strategies, example scene variations, and a list of consistency rules to follow.

The framework includes ready-to-copy prompts for Midjourney (with flags), Stable Diffusion (with recommended sampler, CFG scale, steps, seed strategy, and LoRA notes), and Flux. The underlying descriptors also work in other prompt-based generators.

No. Image generation is probabilistic, so some variation between generations is unavoidable even with a locked prompt. The anchor prompt, seed strategies, and consistency rules significantly narrow the variation, but for pixel-level consistency you would need techniques like training a LoRA or using reference-image features.

Yes. Your description is sent to our server, where an AI model generates the consistency framework. Avoid including personal or confidential information in the description — it only needs visual details about the character.

Yes. The character prompt lock generator is completely free and does not require an account. Describe your character, pick a style and platform, and generate the framework.
