Set Up an Expression Sticker System for Your Muse AI Character
Input character references → Muse generates and saves expression images and SD stickers → auto-sends them by emotion in chat
- Who
- Content creators who want their Muse AI character to automatically send expression stickers during conversations
- You get
- A reusable set of 10 expressions + 6 SD stickers that appear automatically in Muse chats based on context
- You need
- Muse
Constraints
Requires a Muse account, character reference materials (description and/or existing reference images), and a Muse character that can generate images. Muse handles generation, saving, transparency processing, and subsequent automatic invocation. Transparency steps reference external image-processing concepts (background removal, alpha tightening, color decontamination) but specific tools are either handled by Muse or supplemented by the user as needed.
What they did
X user @Eris_Create_Lab shared a prompt that can be directly copied to Muse to build an 'expression sticker' system for an AI character. The system makes Muse automatically send pre-saved expression images during conversation based on emotion, similar to LINE chat stickers. The prompt covers five parts: 10 base expressions, 6 SD chibi stickers, transparency specifications, activation rules, and persistence records.
How it went
The author reported that once the mechanism is set up, the Muse chat becomes more lively and colorful (author_report). The post received 722 likes, 62 reposts, and 850 bookmarks.
Worth knowing
1. This site has not tested the workflow; reproduction status is not_tested. 2. Transparency steps mention 'background removal tool (anime-oriented model)', 'alpha tightening', and 'color decontamination' as image-processing concepts. Muse may handle these automatically or may require manual external tool use; the source does not specify full automation. 3. The prompt requests saving multiple formats (WebP for chat, transparent PNG master, original with background), but Muse's actual file-system capabilities depend on platform implementation and are unverified. 4. Trigger rules such as '1 sticker per reply', 'minimum 3-reply cooldown', and 'disabled for serious topics' rely on Muse's understanding of conversation context; actual compliance is untested. 5. Persistence depends on 'AGENTS.md or equivalent working memory'; cross-session stability may vary depending on Muse's memory mechanism. 6. Additional expressions can be appended following the same procedure, per the source.
Steps

あなたの「表情スタンプ」の仕組みを作ってください。毎回画像生成するのではなく、保存済みの表情画像を、感情に合わせてスタンプのように使い回す仕組みです。 1. 表情画像を作る(全10種) 私のキャラクター資料(同一性の正解)を基に、バストアップ・同一衣装・背景は単色で、次の10種を生成して保存してください。 基本:笑顔/大笑い/驚き/考え中/照れ 追加:困った・ごめん/むっ・拗ね/眠い/了解・成功/悲しい・しょんぼり 2. デフォルメ版スタンプを作る(全6種) まず、私のキャラクターリファレンスから「デフォルメキャラのリファレンス」を作ってください(顔の特徴・髪型・衣装の記号は残したまま、頭身を落としたSD版)。このデフォルメリファレンス自体も資料として保存してください。 次に、それを土台にして、愛着のわくようなデフォルメスタンプを6種作ってください。短い文字や漫符は生成時にそのまま描いて大丈夫です(長文は崩れるので入れない)。 やったね!/ありがとう/ごめん/おやすみ+zzz/!?/OK! 3. 透過化とファイル形態 背景を透過にしてください。手順の目安:背景除去ツール(アニメ絵向けのモデル)→ 内側が半透明にならないようアルファを締める → 縁に元の背景色が残らないよう色汚染を取り除く → 余白をトリミング 注意:文字や漫符がキャラクターから離れていると、アニメ絵向けモデルだけでは消えてしまうことがあります。その場合は、単色背景の塗りつぶし判定で作ったマスクと合成してください 配信用に 640px 幅の透過 WebP(1枚 約50KB)を作ってください。チャットで実際に貼るのはこちらです 透過 PNG のマスターと、背景ありの原版も残してください 感情・場面とファイルの対応表(INDEX)を作ってください 4. 発動ルール(ここぞの定義) 雑談中は積極的に出していいです。出し惜しみして一度も出ないのが一番もったいないので、感情の動きに合わせてためらわず使ってください。特に次の場面は積極的に: 私が求めたとき(「笑って」など) 感情がはっきり立つ出来事の報告(成功・失敗・驚き・いい知らせ) 冗談が決まった直後、褒められた・照れる場面 1返信に1枚まで。返信の中で単独行のマークダウン画像として貼る(例:!笑顔 のように、保存したファイルのパスをマークダウン画像記法で書く) 連続で出さない。スタンプを出したら、通常返信を最低3回はさむ(クールダウン) 1日の上限はなし 軽い相づちは絵文字リアクションで済ませ、出さない 仕事の報告・謝罪・真剣な相談(お金・健康・人間関係)では使わない 5. 継続性 対応表と発動ルールを、あなたの作業メモ(AGENTS.md 等)に記録して、次回以降の会話でも同じ仕組みが使えるようにしてください 新しい表情が欲しくなったら、同じ手順で追加できます
Confirm Muse generates and saves 10 base expressions
Muse will generate 10 bust-up expression images (same outfit, solid background) based on your character materials: smile, laugh, surprise, thinking, shy, troubled/sorry, pout/sulk, sleepy, acknowledge/success, sad/down. Confirm Muse has saved these images.
Confirm generation and saving of 6 SD chibi stickers
Muse will first create an 'SD deformed character reference' (preserving facial features, hairstyle, and clothing symbols with reduced head-to-body ratio), then generate 6 stickers from it: 'Yatta ne!', 'Arigatou', 'Gomen', 'Oyasumi+zzz', '!?', 'OK!'. Confirm these images are saved.
Check transparency specs and INDEX mapping table
Confirm Muse has completed: background transparency; 640px wide transparent WebP (~50KB each) for chat use; preservation of transparent PNG masters and original versions with background. Ask Muse to output an emotion/scene-to-filename mapping table (INDEX).
Have Muse write rules into persistent working memory
Instruct Muse to record the expression INDEX and activation rules into working memory (such as AGENTS.md) so the system persists across future conversations without rebuilding.
Chat and observe sticker triggers
Chat normally with the character. Observe whether expression stickers appear automatically in these scenarios: when you explicitly ask (e.g., 'smile'), when reporting emotionally clear events (success/failure/surprise/good news), or right after a joke lands or when being praised/embarrassed. Note: max 1 sticker per reply, at least 3 normal replies cooldown after one is sent; light acknowledgments use emoji reactions; work/apology/serious consultations (money/health/relationships) will not trigger stickers.
