“Is this keigo correct?” Ten seconds before you hit send, turn anxiety into confidence. Paste an email or chat message (or load a screenshot) and get a rudeness score from 0 to 100, plus exactly what to fix, where, and why. Everything runs in a rule engine on your device — your text never leaves it. ■ Rudeness score (0-100) A dictionary of 40 real keigo mistakes — double honorifics, mixed-up humble and respectful forms, casual “baito keigo”, business NG phrases, excessive politeness, plain casual speech — plus five email-manner checks. Three bands (safe / caution / danger) tell you at a glance whether it is ready to send. ■ Recipient-aware judging Choose client, boss, or colleague, and the strictness adjusts. The same message can be fine for a colleague and risky for a client — now you can see it. ■ Every issue explained Each mistake is highlighted with a suggested fix, a one-line reason, and a category tag, so your keigo actually improves. ■ Corrected full text, one tap to copy The app generates a corrected version of the whole message. Copy, paste, done. ■ Screenshot input Pick a screenshot of LINE or a mail app, and on-device text recognition reads it. Images never leave your device. ■ History Scans are saved automatically so you can review your recurring habits. ■ Privacy - All checks run entirely on your device; works offline - No account required ■ About ads A small banner appears at the bottom. A one-time “Remove Ads” purchase ($0.99, no auto-renewal) hides it forever. No feature limits either way, and no subscriptions. For new hires, career changers, and anyone writing to clients: make the ten seconds before sending a habit of confidence.
