Genuinely Free & Unlimited AI Assistants

These platforms are not traditional language learning apps, but their advanced conversational models provide a 100% free, unlimited speaking partner. By turning on their voice features and asking them to act as your English coach, you can practice natural dialogues without hitting any daily limits. 

• Microsoft Copilot: Offers unlimited free conversation practice. By tapping the microphone icon, you can engage in real-time role-plays (such as ordering at a café or a mock interview) where the AI's tone matches the scenario. You can review a full written transcript afterwards and ask it to highlight vocabulary for improvement. Available on browsers or via the mobile app. 

• Google Gemini: Features a live voice mode called Go Live that enables unlimited talk time. You can explicitly instruct Gemini to correct your grammar mistakes mid-conversation. It will gently break down why a phrase is incorrect and provide natural alternatives.
