Poster Aplikasi Papan Ketik AI Jepang

Glossy Japanese App Store promotional poster for an AI keigo keyboard mobile application, 1:1 square aspect ratio, clean modern tech advertising layout. On the right side, fashion-style portrait of a stylish young Japanese woman holding a silver smartphone. She has tied-back dark brown hair with wispy bangs, sunglasses resting on her head, yellow hoop earrings, soft radiant makeup, and a gentle smile, dressed in a translucent iridescent lavender jacket over a metallic silver top. Background features dreamy pale lavender gradients with soft optical light flares and high-key illumination. On the upper left, small English text reads "ONE TAP. POLISHED JAPANESE." Above the main headline in bold purple Japanese typography: "[送る前に、敬語に整える。]" with a neon lime-green hand-drawn marker swoosh underlining it. Below the headline, black Japanese body text: "[キーボードから離れず、ワンタップで丁寧に。]" alongside handwritten purple text "All Apps!" and Japanese text "[どのアプリでも、すぐ使える。]". Underneath, a row of exactly 4 rounded app icons (Gmail, LINE, Slack, Instagram) followed by an ellipsis "...". In the center-lower area, two floating translucent glassmorphism message cards connected by a small downward purple arrow. Top card marked "Before" in purple script reads "[昨日はありがとう！また連絡します！]". Bottom card marked "After" reads "[昨日はありがとうございました。またご連絡いたします！]" with a small circular purple send button on its right edge. In the lower right, a floating tilted iPhone Japanese keyboard mockup with four suggestion tabs at top: "自然に", "メール", "提案", and highlighted purple "敬語". Standard white QWERTY keys with Japanese function keys ("空白", "改行"). A small adjacent settings card lists: "キーボード設定…", "日本語", and a purple highlighted "敬語ボタン". Lower left app identity: a purple rounded-square app icon with an embossed white keycap graphic, next to title text "[敬語ボタン]" and subtitle "| AIキーボード". Along the bottom center, a lightning bolt icon with text "0.5秒で即変換 / コピーも3倍速", flanked by two laurel badge graphics: "0.5秒 即変換" and "3倍速 コピー*" with tiny footnote "※自社調べ". Across the bottom edge, a bold purple curved banner displays white text "App Store 配信中" with a sleek arrow pointing right. Style: Premium Japanese startup marketing aesthetic, crisp readable UI text, translucent glass cards, subtle drop shadows, vibrant lavender and neon lime accents.
