FAQ
- Microsoft Copilot (summarizing long email threads): In a 40-message thread, get a breakdown of what was agreed, what is still open, and what you need to reply to. Your response time to clients improves noticeably.
- DeepL (replying to overseas clients): Translate your reply written in Korean, then adjust the tone to formal. Double-check names and amounts in the translation.
- Gemini: With just a Google account, you can use the basic features for free. Stronger models and more capacity are available on paid plans.
- Microsoft Copilot: You can chat with it for free in the Copilot app and on the web. However, features inside work documents such as Word and Excel require a paid Microsoft 365 plan or an enterprise license.
- DeepL: A free version is available without signing up, with monthly character and file-translation limits per the official page. If you use it heavily for document work, you will likely need a paid plan.
