AI-Powered Brake Inspection Analyser

Help mechanics diagnose brake issues faster with AI-powered image analysis that detects wear, damage, and provides repair recommendations. Build this SaaS tool in a weekend.

Independent shops lose margin on brake inspections because explaining pad wear to a skeptical customer takes longer than the inspection itself. Techs know a 3mm pad is “yellow soon,” but the service advisor still fights trust battles without visual proof. Generic AI photo tools do not understand rotor scoring, heat checking, or pad taper—and OBD apps ignore physical wear entirely. Shops that do show photos often use messy camera rolls or markup in Paint. “Customers think we’re upselling until they see the pad compared to a new one,” is the recurring advisor complaint. A brake-specific vision pipeline that outputs a standardized wear score, annotated overlay, and recommended line items turns inspection into a sales asset instead of a confrontation.

Built for Developers, Solo Founders.

Suggested stack: Next.js 14 PWA, Supabase Storage + DB, OpenAI Vision API, React PDF / Puppeteer, Stripe Billing, Vercel + Inngest. Weekend scope: about 10 hours.

The Problem

The Solution

Build a mobile-friendly web app (PWA is fine) where a tech captures guided photos: pad profile against rotor, rotor face, caliper area. Upload hits a vision pipeline (OpenAI…

Market Research

US independent repair shops — roughly 160K+ repair establishments; even 0.1% paying $99/mo is a viable bootstrap SaaS.

Competitive Landscape

Tekmetric / AutoLeap MPI — Full shop management with digital vehicle inspections. Broad, not brake-specialized AI scoring; long implementation cycles. Shop SaaS $200–400+/mo

Business Model

Starter ($49/mo) — 100 inspections, 1 location, branded PDFs

Recommended Tech Stack

Next.js 14 PWA — Camera capture, shop login, advisor dashboard.

AI Prompts to Build This

  1. 1. Project Setup

    Scaffold BrakeVision SaaS: Next.js 14, Supabase (shops, inspections, images, overrides), OpenAI vision wrapper returning JSON {wearPct, severity, recommendations[], confidence}. Include Zod validation and shop-level API keys.

Do not build: billing beyond a single shop login, multi-tenant marketplace, or mobile native apps.
Done when: a shop can sign in, create an inspection, upload a pad photo, and receive structured wear JSON.

  2. 2. Core Feature

    Mobile capture flow with SVG overlay guiding pad photo angle. On upload, queue analysis job, display results with editable advisor notes, generate PDF with shop logo. Log human overrides for future prompt tuning.

Do not build: SMS integrations, fleet accounts, or automatic parts ordering.
Done when: an advisor can edit AI notes, export a branded PDF, and see overrides logged against the inspection.

  3. 3. Vision Prompt

    Write system prompt for automotive brake pad analysis: identify pad thickness vs rotor, classify green/yellow/red, list likely services, refuse to guess if image blurry—return confidence score and re-shoot instructions.

Do not build: full vehicle diagnostics beyond brake pads, or any medical/safety certification claim.
Done when: blurry images return a re-shoot instruction and clear images return severity plus recommendations with a confidence score.

  4. 4. Sales Landing

    Landing page for shop owners: ROI calculator (extra brake jobs/week), 20 free inspections CTA, testimonial layout, comparison vs generic MPI modules. Dark garage aesthetic with high-contrast safety yellow accents.

Do not build: a marketing CMS, A/B testing suite, or paid ads dashboard.
Done when: the page states the offer, shows the ROI calculator, and CTAs to start the free inspections.
