Adaptive Learning Companion Live Application

PathMindAI

An intelligent learning companion that monitors learner progress, helps identify key conceptual gaps, and scaffolds targeted learning exercises to support iterative improvement.

  • Dynamic Lesson Scaffolding: Generates progressive curriculum modules aligned to specific student skill gaps.
  • Submission Assessment: Analyzes assignments using structured criteria, offering concrete pointers for revision.
  • Continuous Learning Flow: Guides students through iterative problem solving rather than simple passive reading.
Claude API Integration
PathMindAI integrates the Claude API on the server to draft adaptive lesson outlines and deliver criteria-based feedback on learner submissions.

Career Mentoring & Simulation Live Application

PassItAI

A comprehensive interview simulation and mentoring platform designed to help job candidates build confidence, refine professional communication, and receive structured evaluation on mock interview responses.

  • Scenario-Driven Practice: Simulates industry-specific interview tracks across engineering, product, and leadership.
  • Rubric-Based Answer Analysis: Evaluates candidate answers on structure (STAR method), technical depth, and clarity.
  • Post-Interview Action Plan: Provides specific revision tips and follow-up guidance to address communication gaps.
Claude API Integration
PassItAI leverages the Claude API to analyze candidate interview responses against industry criteria and generate detailed diagnostic evaluations during and after practice sessions.

Engineering Methodology

Built for Substantive Educational Impact

Rather than creating generic wrapper interfaces, Ethanek grounds AI capabilities in practical pedagogic principles and verifiable criteria.

Rubric-Based Grounding

We support structured practice with explicit rubrics. Learner submissions and interview answers are evaluated against clear criteria, aiming to provide constructive pointers grounded in the submitted text.

Secure Server Architecture

All interactions with the Claude API are routed exclusively through backend services. API credentials remain confidential on the server, enforcing output schema validation and application-level request limits.

Iterative Practice Loops

True mastery requires revision. Both PathMindAI and PassItAI prioritize multi-stage iteration: students submit work, review specific pointers, apply revisions, and observe measurable improvement over time.

Organization

The People Behind Ethanek

Ethanek is an independent, bootstrapped EdTech product team started in 2026 by Ethan Tran (Trần Văn Hậu). Our four-person team develops and operates PathMindAI and PassItAI.
