TEACHER.PRO
Private AI English Tutor that runs offline
TEACHER.PRO is a private AI English tutor platform powered by local LLMs, voice recognition, and pronunciation analysis. Unlike cloud-only solutions, it runs locally, providing privacy-focused language learning with personalized conversations and interactive training.
Thanks for highlighting TEACHERPRO! This is my first product launch; I’m nervous but excited to share what I’ve built.
What is TEACHERPRO?
It’s a fully offline, privacy-focused English tutor that runs four AI models directly on your computer. No cloud. No data leaks. No subscriptions. The student's voice and progress data never leave the machine.
The Processing Pipeline – How the four models work together:
1. Audio Processing: Professional noise reduction and volume normalization (LUFS) clean up the raw microphone input.
2. Speech Recognition (Whisper – OpenAI): Transcribes what the student said, preserving pronunciation errors.
3. Acoustic Analysis (WavLM – Microsoft): Compares the student's speech to a native speaker's, generating a phonetic similarity score.
4. Forced Alignment (Wav2Vec2 – Meta): Identifies exactly when each sound was pronounced.
5. Conversational AI (Qwen 2.5 – Alibaba): Acts as a personal tutor, offering feedback, explaining rules, and keeping the conversation flowing.
All models are orchestrated locally via FastAPI and Ollama, featuring a Vanilla JS frontend and SQLite for progress tracking.
Privacy and Offline Mode
The entire pipeline works without an internet connection. When a connection is available, the software can optionally enrich conversations with real-world context (weather, culture, currency) using public APIs, but it never sends user data.
What’s included in the sale
- Full source code (Python/FastAPI + Vanilla JS)
- Windows installer (.exe)
- Pre-populated database (over 260 words, 80+ dialogues, achievements)
- Architecture documentation, security audit report (Bandit), and INPI registration (Brazilian intellectual property office)
I developed this entirely on my own. It involved two years of self-directed learning and two months of intensive development with AI assistance. Now, I am looking for a buyer capable of scaling the project.
I am available to answer questions or provide a live demonstration. Thank you for reading!
