Ask a room of AI creators why their character drifts and most will blame the model. Watch their prompts, though, and the cause is clerical: she is re-described from memory every session, and memory edits. One week she has “long teal hair in twin braids,” the next “blue-green pigtails, kind of,” and the audience watches a stranger take over the profile. The fix is boring and total — write her down once, on a character sheet you paste, not a description you retype.
The anatomy of a sheet
A working character sheet has five anchors, in this order: age (always 25 or over, stated as a number), hair (colour, length, one default style), build (two or three words, no more), face (one or two durable details — violet-grey eyes, a strong brow, a small star hair clip she always wears), and a signature (the item that survives cropping). Everything else — wardrobe, set, light, pose, mood — is a scene line, and scene lines are supposed to change. Think of it as a loadout: the sheet is the character, the scene lines are the level she is playing today.
Two rules keep the sheet healthy. First, anchors are phrased positively and concretely: “long teal hair in twin braids” survives generation; “stunning hair” is an opinion the model interprets differently each time. Second, the sheet is versioned. When you deliberately evolve her — a new hairstyle arc, a new signature — save the new sheet as version two and date it, so old sets remain reproducible and a respawn never overwrites your history.
Running a season on the sheet
Production then becomes mechanical in the best way. Brief a set by pairing the sheet with three to five scene lines sharing one setting and light setup. Generate wide at the standard model’s 6-credit price — or spend the day’s free check-in frame on the first test — cull to the best third, and only then spend on edits, swaps and upscales. When a frame comes back off-character, the diagnosis is fast: either a scene line contradicted an anchor (a “short bob” scene line fighting the sheet’s twin braids) or the sheet itself has a vague anchor to tighten.
What the sheet cannot do
It cannot rescue a character who was never visually decided. If your anchors are adjectives — gorgeous, perfect, flawless — no system will hold her. Decide the woman on paper first. The sheet is not where creativity happens; it is where creativity is stored.
