Before you replace it, let’s understand it and see whether we can fix it.

What it is

LET’S FIX IT AI is an honest repair-diagnosis assistant for everyday products (car remotes, Bluetooth speakers, phones, and more). Users describe a problem (optional photo), get structured follow-ups, an evidence ladder (Observed / Possible / Unknown), real YouTube repair videos, and India parts search links (Amazon.in · Flipkart · Meesho) — without inventing prices, fake videos, or false confidence.

Prize tracks

• Best Use of Gemma 4 — multimodal text + image diagnosis with open-weight gemma-4-26b-a4b-it via Gemini API; focused community repair tool
• Best Open-Source AI Project — open-weight Gemma is core to how diagnosis works (structured JSON agent harness)

How it works (minimal)

User chat (+ photo) → POST /api/diagnose (Hono) → Gemma 4 → Zod-validated JSON → UI (chat, Quick Answers, evidence, videos, parts)

Tech stack

• Frontend: React 19, TypeScript, Vite, Tailwind (Material Design 3), React Router
• API: Hono on Node (local + Vercel serverless)
• AI: Gemma 4 primary (Flash Lite fallback only if Gemma fails)
• Validation: Zod shared diagnosis schema
• Integrations: YouTube Data API v3, merchant search URLs, optional Supabase auth/My Repairs
• i18n: English + Telugu (UI + AI replies)
