PromptFluent - Learn AI

PromptFluent is the app that teaches you the language of AI. Master prompt engineering, technical vocabulary, and professional communication for ChatGPT, Claude, Copilot, and beyond. Works for English, Spanish, and Portuguese (Brazilian) speakers.

THREE NATIVE LANGUAGE MODES

Choose your language on first launch:
- English speakers: 40 AI-focused lessons on prompt engineering and technical communication
- Spanish speakers: 80 bilingual lessons combining English learning with AI terminology
- Portuguese speakers: the same 80 lessons; the interface and most reference modules are in Portuguese, while lesson explanations, vocabulary and grammar support text are still shown in Spanish while that translation is completed

THREE LEARNING MODES

STUDY - Work through structured lessons across 16 units covering four proficiency levels (Starter to Architect). Each lesson includes teaching content, vocabulary, grammar, dialogues with AI, and a quiz. Browse our encyclopedia of 560+ tech terms across 15 categories, study with flashcards, master English grammar with 24 tech-focused lessons, and explore 60 copy-ready prompt templates. Discover 10 AI use cases, a glossary of 20 AI tools, 24 reading comprehension passages, and 16 dev culture notes.

PRACTICE - Build real AI skills, grouped the way you use AI. ASK: Prompt Workshop (write prompts and get scored on task, detail and technique), Prompt Lab (see how each part of a prompt changes the answer) and Use AI at Work (24 workplace prompts). REFINE: Refine the Answer (pick the best follow-up when the first answer misses). EVALUATE: Trust Check (judge AI answers with a 4-point checklist) and AI Fact-Check & Safe Use (catch AI mistakes and know what not to paste). REVIEW: Spaced Repetition Review Hub. Spanish and Portuguese speakers also get English for AI: Daily Drills, AI Conversations, Listening Hub, Sentence Scramble, Error Drill, Email & Messages and Verb Hub.

PLAY - Prompt Debugger (40 challenges to find what a weak prompt is missing) and Daily Challenges, plus Story Mode, Context Guesser and Translation Shootout for English learners.
