윌리ai 이메일 어시스턴트 (Willi AI Email Assistant) is a Chrome extension powered by ChatGPT that helps Korean speakers write professional emails in 12 languages. Instead of struggling with translation tools or awkward phrasing, users type their message in Korean and the extension generates a natural, context-aware email ready to send. Developed by willi.ai, the tool targets professionals who communicate internationally — from overseas sales teams and trade specialists to academics, diplomats, and global enterprise employees.
Key Features
- 12-language email generation: Produces emails in English, Japanese, Chinese, Spanish, French, German, and six other languages from Korean input. Unlike standard translation tools, the output is natural native-level writing rather than literal word-for-word translation, making it suitable for professional correspondence.
- Context-based sentence creation: Uses ChatGPT to analyze the user’s Korean keywords and intended meaning, generating complete and well-structured sentences that match the requested tone and purpose. Users can fine-tune creativity levels for more direct or more expressive results.
- Tone and category selection: The companion web platform at willi.ai supports multiple tones including gentle, witty, direct, warm, professional, casual, and persuasive. Email categories cover general correspondence, work communication, student and parent needs, legal drafting, international trade, and recruiting outreach.
- Beyond email: The platform also generates email replies, cold emails, blog articles, ad copy, and cover letters, making it a versatile AI writing assistant for Korean-speaking professionals.
- Privacy-first design: According to its Chrome Web Store listing, the developer declares that no user data is collected, sold to third parties, or used for unrelated purposes. The extension operates with a minimal data footprint.
Use Cases
- International business correspondence: Sales professionals, trade specialists, and foreign exchange dealers use the extension to draft emails to overseas clients and partners without relying on generic machine translation that often produces awkward or incorrect phrasing.
- Academic and research writing: Professors, PhD candidates, and researchers across science, engineering, social sciences, and humanities draft multilingual papers, reports, and project descriptions by entering Korean thought flows and receiving coherent drafts in the target language.
- Aviation and maritime communication: Pilots, captains, flight crews, and air traffic controllers use the tool for cross-border operational communication where precise language matters.
- Patent and technical writing: Patent attorneys, industrial engineers, food technology engineers, energy engineers, and network design engineers leverage the tool for global collaboration and precise technical documentation.
- Daily workplace email: Employees at foreign-owned companies use it to communicate naturally with international colleagues, avoiding the awkward phrasing that often results from direct translation and saving significant time on email composition.
