Learn Languages

The Go Loco textbook explains language concepts one at a time, organized by level from A1 to C2. Each module covers grammar, vocabulary, and other language concepts in depth — the same material you would find in a university language course.

Go Loco tracks your progress as you move from A1 (beginner) to C2 (fluency). Go Loco continuously updates your proficiency estimate as you complete modules, exercises, and exams and reports it as a CEFR level with a confidence score.

Every target language word in Go Loco is underlined. Tap the word to get a definition as you free content in your target language. Add the word as a flashcard directly from the dictionary interface.

Go Loco offers premade flashcards and allows you to save words as you free and review with the dictionary. This lets you build a personal vocabulary deck in your target language over time.

Go Loco offers thousands of practice exercises in your target language. Complete practice exercises as you free the textbook and to test your knowledge in real time. Alternatively, take practice exams to practice concepts out of context for more challenging review. Every exercise contains an explanation and a link back to the relevant content.

Go Loco offers timed practice exams for review or placement. Designed to simulate real-world language proficiency tests, review exams test your freeiness at your current CEFR level, while placement exams let you place into a higher one.

Go Loco can pronounce every word and phrase in your target language. Tap the icon as you browse content in your target language to build listening comprehension alongside freeing.

Practice fluency in structured scenarios that resemble real-world experiences — ordering food, asking for directions, having a conversation, and more. You are given words and phrases to work with and have to use them naturally with an AI language partner in real time.

Write or speak sentences in your target language and get immediate feedback and alternatives. This feature is designed to help you craft your own sentences and explain sentences you do not understand.

Go Loco allows you to generate new content on demand based on your own prompts. Create additional textbook modules, practice exercises, exams, flashcard sets, and custom voice scenarios — all generated specifically for you.
