Turning AI into a Dedicated & Free Personal Teacher

I am Le Vu Ngan Lam. Enginuity didn't start from a grand business plan, but from real needs in my own English self-learning journey.

Back then, because I couldn't afford center classes, I chose to learn entirely through AI tools. However, learning through fragmented chat lines was quite challenging. I often had to switch tabs, draft prompts, copy my work, wait for results, then manually archive them... These repetitive manual tasks made me lose focus and took too much time for 'ops' instead of actually learning.

'Why isn't there a system to automate these things, so I can only focus on knowledge?'

That is the reason Enginuity was born. Instead of fragmented conversations, I created a more professional and systematic learning interface. My goal is to turn AI into a true companion, helping everyone learn English in a focused, effective, and completely free way.

Key Functionalities

Enginuity is built with a focus on systematic learning and AI-driven automation.

Module 1

Vocabulary Mastery (CAM Method)

Master English vocabulary through a scientifically-backed three-phase system designed for long-term retention. Move from simple discovery to active contextualization, and finally to peak production where you receive granular AI feedback on your writing accuracy.

Module 2

IELTS Speaking Simulation

Practice for the IELTS Speaking exam with full-length simulations (Part 1, 2, and 3). The system mimics real test conditions and provides a comprehensive breakdown of your performance based on official IELTS criteria, including detailed band scores for Fluency, Lexical Resource, and Pronunciation.

Module 3

IELTS Writing Assistant

Elevate your writing for both Task 1 and Task 2 with a sophisticated dual-mode editor. Choose between Standard Mode for pure practice or AI-Assisted Mode for guided drafting. Get immediate AI evaluation and an estimated band score based on official grading standards.

Module 4

Personalized Wordbook

A centralized linguistic repository for every word and phrase you encounter. Organize your vocabulary with powerful search, filtering, and batch operation tools like merging or deleting entries, while tracking your mastery progress over time.

Module 5

Transparency & AI Control (BYOK)

Enginuity puts you in control with a 'Bring Your Own Key' model. Connect your own Google Gemini API key to gain full transparency over AI costs and performance. Monitor every token spent with a detailed history dashboard and usage analytics.

Project Overview

A modern, AI-powered platform for English self-learners focusing on vocabulary mastery through the CAM Method (Contextualization, Activation, Mastery) and IELTS preparation. Key features include a three-phase vocabulary system, IELTS speaking simulations with granular AI feedback, and a dual-mode writing assistant for Task 1 and Task 2. It empowers users with a 'Bring Your Own Key' (BYOK) model for complete transparency and control over AI costs.

Challenges & Solutions

While the features may appear straightforward on the surface, the end-to-end implementation involves high complexity across multiple synchronized learning phases. Developing robust backend logic, responsive frontend interfaces, and comprehensive test suites to handle numerous edge cases required significant time and effort. Additionally, the 'Bring Your Own Key' model currently limits access to advanced API features such as image processing, high-fidelity voice generation, and accurate speech-to-text, which affects the overall precision and breadth of automated feedback.

Results & Impact

Successfully engineered a comprehensive, multi-phase learning management system that effectively automates complex self-study flows. Despite the limitations of individual API keys, the platform delivers high-quality linguistic analysis and provides a structured, professional-grade environment for IELTS preparation.
