What does Keigo app do?
Keigo app is a specialized AI tool that helps users write and refine Japanese business emails. It focuses on the correct use of honorifics (keigo) and polite language, which are essential for professional communication in Japan. You can describe a situation, and the AI will generate a complete, appropriately worded email. It also reviews drafts you provide, suggesting improvements to make the language more natural and respectful. This takes the guesswork out of formal Japanese correspondence.
The tool works by letting you choose from seven common email categories and adjust the tone for your specific recipient. It provides a 'politeness score' for generated text. For corrections, it doesn't just fix errors—it explains why a phrase was changed, which is helpful for learning. You can save frequently used phrases as templates and manage different email signatures for various projects or companies.
This tool is most useful for anyone who needs to write formal emails in Japanese but isn't completely confident with the nuanced rules of keigo. This includes new employees, non-native speakers, and even native speakers who want a second opinion on important messages. It's practical for daily tasks like scheduling meetings, making requests, or sending apologies, ensuring your communication always leaves a professional impression.
