+# Feedback voice recommendations
+
+Duolingo's public product writing consistently puts the answer first, keeps the immediate interaction small, offers explanation as a second layer, and makes the end of a session encouraging while still naming what needs practice. That pattern is useful here, but Bert's Atlas should keep an original travel-and-curiosity voice rather than imitate Duolingo's phrases.
+
+Research basis:
+
+- Duolingo, “Explain My Answer is now free for all learners”: https://blog.duolingo.com/explain-my-answer-now-free/
+- Duolingo, “Introducing Duolingo Flashcards”: https://blog.duolingo.com/duolingo-flashcards/
+- Duolingo 101: https://blog.duolingo.com/duolingo-101-how-to-learn-a-language-on-duolingo/
+- Duolingo, “How we improved the streak”: https://blog.duolingo.com/improving-the-streak/
+
+Recommended original patterns:
+
+- Correct: “Flag filed. Nice work.”
+- Incorrect: “That was {answer}. Look for {short distinction}.”
+- Overtime: “Time's up. You still found it.”
+- Continent hint: “Map clue: {continent}.”
+- Choice hint: “Two decoys are leaving.”
+- Fact hint: “Bert's clue: {answer-safe fact}.”
+- Results: “Atlas packed: {score} points · {accuracy}%.”
+- Review: “Worth another look: {countries}.”
+- Streak: “{days} curious days in a row.”
+
+Keep feedback to one idea per line. Name the correct answer after a miss, but never include it in a pre-answer clue. Avoid shame, exaggerated celebration, and claims that a streak proves mastery.
