A conversation-first language learning experience built around how people actually learn to speak.

LinguaAI is an AI-powered language companion designed to make language learning feel more personal, practical, and human. Instead of relying on repetitive drills alone, it guides learners through personalised lessons, real-world scenarios, and AI-powered conversations with Lingui, their always-on learning companion. The challenge was simple: most language apps teach you words, but few help you actually speak. I designed LinguaAI around conversation, personalisation, and momentum, creating an experience that adapts to each learner while making progress feel rewarding.

Project Overview

A calm, intelligent companion for learning a language, built around conversation rather than flashcards.

LinguaAI guides each learner from their very first tap: a personalised setup, a motivating dashboard, real-world scenarios, and an always-on AI tutor named Lingui that makes practice feel like chatting with a friend.

The Problem

Most language apps teach words. Few teach you to actually speak.

Learners drown in streak bait and rote drills, then freeze the moment a real conversation starts. Motivation fades because the lessons never feel like their life.

Design Goals

Four principles guided every screen.

Make it personal

Six questions at setup shape the learner's own path.

Practice by speaking

Lessons end in a reply to Lingui, not a score.

Keep momentum

A goal ring and a streak make returning effortless.

Feel human

Chat bubbles, encouragement, corrections that explain.

User Journey

From curious to conversational.

Seven moments map the full arc, each designed to lower friction and build confidence.

Onboarding Experience

6 questions. A lesson plan built around you.

Lingui asks like a friend, not a form. Each answer (your name, languages, reason, level, and pace) quietly tailors the entire experience that follows.

Conversational tone — every step framed as a chat bubble from Lingui.

Auto-detected defaults reduce taps — like pre-selecting the device language.

A green "You're all set" moment turns setup into a small celebration.

Dashboard and Gamification

Progress you can feel every single day.

The home screen greets you by name and turns learning into momentum: a daily goal ring, a streak to protect, and a clear "continue where you left off."

Streak system

A flame ring fills as daily goals complete — protecting the streak becomes the habit loop.

Today's goals

Lessons, assignments, and quizzes shown as simple fractions — 1/1, 3/3, 2/3.

Levels & XP

"Level 3 Explorer" gives identity and a sense of steady advancement.

Continue learning

A live progress bar and lesson checklist make resuming effortless.

Scenario Learning

Learn by living the moment.

Instead of word lists, learners step into a story: "You just arrived at a park in Madrid." Each scenario plays out as a guided conversation with translations, choices, and a satisfying finish.

AI Assistant

One tutor, three ways to reach it.

Lingui is the same companion throughout: practise a conversation, translate something you just heard, or take a one-minute drill. Whichever you pick, the reply comes back in the same voice.

Practice Conversations

Role-play real-life topics in your target language.

Quick Translations

Type anything and get an instant translation.

Daily Challenge & Grammar Help

1-minute drills and on-demand rule explanations.

Real-time feedback

It corrects, encourages, and keeps the conversation flowing.

When you answer "Buenos días," Lingui replies "Perfecto" and plays out the waiter's response, modelling natural dialogue and reinforcing what you got right, instantly.
