Hello, this is the admin. To get straight to the point, it's best to create a separate translation-specific prompt, and you can reduce tone inconsistencies with a few structural methods. First, it helps to understand the root cause. As documents get longer, the influence of the initial instructions weakens, and when each paragraph has a different tone in the source text, there's a tendency to follow that tone exactly, which causes formal and casual speech to go back and forth. I'd like to recommend a few practical tips. 1. Don't just list rules in the system prompt—add 2-3 example sentences in your desired tone directly. Example sentences are more effective for fixing tone than rule descriptions. 2. Don't put long documents all at once. Translate them in paragraph or section units sequentially, and include the previous translation result in your next request so the tone flows consistently. 3. After translation is complete, as a final step, ask separately to check the newly translated result for any paragraphs mixing formal and casual speech and unify them. Often it will catch inconsistencies on its own. 4. If you're using repeated translation rules, fix them in the project features or style settings so you don't have to rewrite the prompt every time. For the literal translation issue, giving concrete instructions about the output format—like 'reconstruct it as natural Korean sentences'—tends to work better than abstract instructions like 'translate naturally.'
