Here is the most common beginner heartbreak: Monday’s portrait is perfect, Tuesday’s is a lovely stranger, and by Friday your page stars four different women who happen to share a dress. Nobody warned you that the generator has no memory — every description is interpreted fresh, and the description in your head quietly edits itself each time you retype it. The cure takes five minutes: write your character down once, as a little paragraph you paste instead of re-typing.
The five friendly lines
A good character brief — call it her ID card — answers five small questions, in this order. How old? A number, always 25 or over (“fictional 28-year-old woman”). Hair? Colour, length, and how she usually wears it (“long chestnut hair worn loose”). Build? Two or three honest words, no poetry (“curvy, soft build”). Face? One or two details that survive a thumbnail (“warm brown eyes, a wide smile”). Signature? The one thing that is only hers (“tiny gold star earring in her left ear”).
Notice what is missing: gorgeous, stunning, perfect, beautiful. Compliments are not descriptions — the generator cannot hold onto them, because each one means something different every time it reads them. Concrete beats flattering, every single time.
A worked example
Here is an ID card in the wild, doing its job: “Fictional 28-year-old woman, long chestnut hair worn loose, curvy build, warm brown eyes and a wide smile, tiny gold star earring in her left ear.” After that paragraph, each new picture just adds today’s scene: the coral sundress at the boardwalk, the yellow raincoat at the café. The scene changes; she does not. Two months from now, a fan scrolling fast will still stop at her thumbnail and think — oh, it is her.
Keeping the card alive
Save the paragraph somewhere you will actually find it — a notes app is perfect. If she ever gets a deliberate makeover (new hairstyle era, a second signature), save the new card as version two with the date, rather than scribbling over version one. Old sets stay reproducible, and your future self says thank you. And if a picture ever comes back off-character, do not blame the model first: check whether today’s scene sentence accidentally argued with the card (“short bob” is a hairstyle, scene-writer). Fix the sentence, keep the card.
