Introduction to the Heero app
Heero is an artificial intelligence-based language learning app designed specifically to help users improve their speaking skills in a natural, engaging, and pressure-free way.
Unlike many traditional apps that focus primarily on grammar exercises and vocabulary memorization, Heero prioritizes real conversation, which is often the most difficult skill to practice-especially if you don’t live in a country where the language is spoken.
Many people do not have the opportunity to speak with native speakers every day or to use the language in real contexts. This is where Heero makes a difference: thanks to artificial intelligence, Heero offers realistic conversations that help you speak consistently, gain confidence, and improve fluency – anywhere or anytime.
What’s more, Heero is not just limited to AI: it also offers online English lessons with certified teachers for even more personalized and targeted support that can adapt to your specific needs and lead you to achieve your language goals.
What is Heero?
Heero is not your typical language learning app. While many platforms overload you with grammar exercises and vocabulary flashcards, Heero turns the tables by putting speaking at the center of your learning journey. This innovative approach helps users overcome language barriers, allowing them to focus on speaking naturally and fluidly.
Heero supports five main languages-English, Spanish, French, German, and Italian-and gives users the freedom to practice at their own pace and needs. Heero’s artificial intelligence listens, corrects and motivates without judgment, creating a safe and stimulating environment to practice the language. Whether you are a complete beginner or reviewing to prepare for a trip, Heero ensures that the language does not remain only in your mind, but is finally spoken, thus improving your fluency and confidence in speech.
One of the distinctive features of Heero is that it allows users to converse freely with an AI agent, who not only answers questions but also stimulates the conversation by suggesting new topics, correcting grammar and pronunciation errors, and offering suggestions for improvement. In addition, Heero allows you to choose from 17 different accents, so you can improve your comprehension and pronunciation in an even more targeted way.
Heero is designed for anyone who wants to improve their language skills, flexibly and without stress. You can practice whenever and wherever you want, with no time or place limits, and without the fear of making mistakes. Heero’s main goal is to make language learning a natural and fun experience.
But that’s not all. Heero also offers online English lessons with certified teachers. You can choose a tutor to help you focus on specific areas, such as conversation, grammar, or vocabulary, depending on your needs. Lessons are customized to fit your level and the topics that interest you most, to make learning more engaging and motivating. And, of course, the lessons are private, so the tutor will focus only on you.

- Free conversation with AI

1. AI Conversational – Talk whenever you want, about anything.
At the heart of Heero is a powerful AI designed to hold natural conversations with you, just like a language exchange partner, but always available. You can choose to communicate through:
✅Text
✅Audio messages
✅also live voice calls, which simulate real-time conversations
You are free to talk about pretty much anything you want – your weekend, your hobbies, your goals, your favorite show on Netflix. Heero is designed to keep the conversation flowing and adapt to your interests and language level.
2. Instant and intelligent feedback
Every interaction is a learning opportunity. After each message (written or spoken), Heero provides real-time corrections and suggestions, showing:
- Grammatical errors and how to correct them
- Pronunciation errors with phonetic support and suggestions
- Evaluations on fluency, completeness and accuracy of pronunciation
- Suggestions for more natural or native-like expressions
It’s like having a tutor who doesn’t interrupt you while you’re speaking, but helps you reflect and improve afterwards.
3. Multilingual training and in different accents
Heero supports five main languages-English, French, Spanish, German and Italian-with plans to expand further. What makes it unique is the ability to:
✅Practice in multiple languages with one account
✅Choose from 17 different accents (British accent, American, Australian, Irish just to name a few)
This feature helps develop not only speaking skills, but also listening skills, especially if you are preparing for real interactions in a specific country.
4. Personalized conversations, roleplay, and contextualized learning
Heero adapts to your level, interests, and goals, giving you a dynamic learning experience that feels more like talking to a super-patient, experienced friend than using an app.
✅Practice with real-world roleplays such as job interviews, ordering food at a restaurant, making travel plans, or informal conversations
✅Learn vocabulary in context, not in isolation – Heero introduces new words naturally during conversations
✅Read news from around the world and talk about it with Heero to develop your real-world discussion skills
✅Curious about grammar? Ask Heero to explain the rules or give examples – it’s like having a tutor on hand
You can also ask Heero for travel tips, book recommendations, recipes or random trivia about what you like
5. Vocabulary tips and expressions
During conversations, Heero introduces new words and expressions in context, helping you naturally expand your vocabulary without having to memorize isolated word lists.
You’ll learn to say things as a native speaker would, beginning to recognize patterns and complete sentences-essential for fluency.
6.Progress tracking
Each session contributes to your personalized learning statistics. Heero tracks:
- Your daily practice continuity
- The number of words spoken
- Improvements in key speaking metrics
This creates a sense of momentum and accountability, motivating you to come back every day-even if only for a few minutes of speaking.

Heero is not limited to the AI app but for those who want to learn English also offers one-on-one lessons with experienced teachers.
You will be able to choose your tutor, the day of the lesson, and the topic. Alternatively, the teacher will create a personalized plan based on the user’s initial level.
