A language app that corrects the sentence you actually wrote

GogaQ is an iPhone and iPad app designed to help users practice forming sentences in a foreign language and receive corrections to improve their language skills. The app provides sentences grouped by situation and CEFR level, allowing users to practice speaking in a variety of contexts. Users answer the sentences in their own words, and receive feedback on what needs to be deleted, added, and why.

For example, the app presents the prompt "Please send me the documents by tomorrow." and asks the user to write their own version. If the user writes "Envoie-moi les documents jusqu'à demain, s'il te plaît," GogaQ would give it a score of 78 out of 100, marking "jusqu'à" as "d'ici" as the correct correction. The app explains that "jusqu'à demain" means "until tomorrow," which does not convey a deadline. Instead, "d'ici demain" would be more appropriate for expressing a deadline.

The app also focuses on politeness, teaching users how to adjust their language depending on the audience. For instance, the sentence "Envoie-moi" (tu) would be suitable for a close colleague, while "Pourriez-vous m'envoyer" (vous) would be more appropriate for a client or manager. Users can listen to the corrected sentence, hear a more natural alternative, and save it to their review cards for later study.

GogaQ offers ten languages for learners to choose from, including French, English, Japanese, Chinese, Korean, Spanish, German, Indonesian, Vietnamese, and Thai. The app is available in eight native languages, with English and Japanese featuring pre-recorded AI voices in various accents. Users can access the sentence books and wordbooks without any points or time limits.

The AI features, such as corrections, conversation, and news articles, require points, which are obtained through a free initial allotment of 20 points upon creating an account or by purchasing additional points as needed.
