Chinese Roleplay Character Card Builder

A character card is the structure that keeps a model in character

When you ask a Chinese chat model — Doubao, Kimi, DeepSeek or Qwen (通义千问) — to roleplay, the difference between a flat, easily-broken impression and a character that feels alive comes down to how clearly you brief it. A one-line "play a pirate captain" leaves the model improvising everything, so it drifts, contradicts itself, and slips back into assistant mode. A proper character card fixes that by naming the role, the identity and backstory, the personality, the speech style, the world and scene, the opening line, and the ground rules. This builder keeps that structure for you: fill the fields, and it assembles a clean card that opens with a "请你扮演…" role line, then lays out each part under a clearly headed Markdown-style section the model can read at a glance — exactly the kind of sheet a careful writer would prepare by hand, only assembled in seconds.

The highest-leverage fields are the name, identity and personality, because they set who the character is before anyone speaks. A specific identity — "a retired sea captain in a small harbour town, weathered and slow to trust" — does more than a dozen loose adjectives. Personality then governs how the character reacts: faced with the same question, a guarded character and an eager one answer in opposite ways, and naming that pattern up front is what stops the model from flattening every reply into the same neutral voice. Make each field concrete: rather than "friendly", write "warm with regulars, brisk with strangers, never raises their voice".

Speech style and ground rules separate a sketch from a character

The fields people underrate are speech style, the opening line and the ground rules. Speech style and catchphrases are what make the character recognisable — a few signature phrases pin the voice better than any amount of description. The opening line eases the model into character so the very first exchange already feels immersive. And the ground rules — stay in character, never break the established setting, never decide for the user, never claim to be an AI — are the limits that keep a long conversation from collapsing. None of these constrain the story; they protect it, which is why a single extra line of "the character would never…" is consistently the cheapest way to keep a session coherent.

Because the output is structured plain text, the same card is portable across every major Chinese chat model and works just as well on ChatGPT, Claude or Gemini. Write it in Chinese when you want natural, idiomatic Chinese dialogue; the structure travels regardless of language. And because the whole tool runs locally in your browser, you can iterate freely — adjust the personality, tweak the opening line, copy again, and test — without anything you type ever leaving your device, being sent to a model, or being stored. Treat the first card as a draft: run a few turns, notice where the character drifts, and tighten the matching field. This builder is meant for wholesome, age-appropriate roleplay — writing practice, interactive fiction, language drills, original-character sheets, tabletop NPCs and guide personas — so keep the content kind and suitable, and you will end up with a clean, reusable card you can return to any time.
