Localize Japanese content without killing what makes it good.

Machine translation gets the words. It loses the voice — the tsundere who becomes a different person by chapter 3, the title that reads fine and sells nothing, the sound effect everyone just… skips. This skill does the part that actually matters.

Built by a native Japanese speaker who ships to both the Japanese and overseas markets — dual fluency a generic translator can't fake.

Start in seconds — one question

You don't need to know which mode you need. Tell it what you're localizing and it routes you. Paste what you have and it picks for you.

What it does (7 modes)

🪞 Character Voice DNA — paste 5+ lines, it extracts the character's archetype, signature moves, and English voice rules into a Voice Card, then keeps that voice consistent across every line. (15-archetype library: tsundere, kuudere, ojou-sama, kansai-ben, and more.)

🛒 Real-time App Store / Google Play analysis — web-searches your category's top apps right now and positions your listing to win (real competitors, cited — never invented).

🚨 Cultural Landmine Detector — scans for cultural / religious / political sensitivities before launch, by market (US / China / Korea / SEA / Middle East), with specific fixes.

🏆 Viral Title Generator — researches how similar titles succeeded, then gives options that work in search and on the shelf (not a dead-literal translation).

💥 Onomatopoeia Translation — the hardest part of manga/game localization, with a context-aware dictionary (ドキドキ, もふもふ, しーん…).

🇯🇵 Reverse Localization + Japan market read — English → Japanese, plus an honest, no-fake-numbers read of cultural fit, demand, competition, and lift.

🌏 Simultaneous multi-language output — one input → many languages, each culturally adapted.

Built to be honest

No invented "/100" scores. No made-up competitor names. Platform character limits are verified, not guessed (they change). It judges with reasons, and asks instead of hallucinating when you give it too little.

Who this is for

Indie game/app devs shipping a Japanese title overseas (or an English one into Japan). Manga/anime translators who refuse to flatten a character. Anyone who's watched a great Japanese product flop abroad because the localization was technically correct and culturally tone-deaf.

Built by someone who lives in the source culture and sells in both markets. The library, the dictionary, and the landmine knowledge come from there — not from a dictionary.
