StudyBuddy AI: A Local AI Study Companion Powered by Gemma 3 4B

Description and use

StudyBuddy AI consolidates explanation, practice, testing, revision, and planning into a single local application, ensuring privacy and no cloud‑API costs.

Problem

Students struggle to understand difficult topics and organize exam preparation, needing a continuous learning flow rather than isolated Q&A.

Outcome

StudyBuddy AI provides a unified, privacy‑preserving study workflow that replaces multiple disparate tools, enabling students to explain concepts, practice, test, revise, and plan all locally.

Workflow

• Enter topic
• Request explanation
• Choose follow-up action (simpler explanation, analogy, quiz, revision sheet, study plan)
• Generate and review quiz
• Review mistakes and explanations
• Generate revision sheet
• Create multi‑day study plan
• Save resources to localStorage
• Track progress and revisit saved items

Evidence

StudyBuddy AI turns that workflow into one application.

The most important lesson was: AI should be treated as a component of the product, not the entire product.
