WrenchSpec is an AI-powered tool recommender for home mechanics. You enter your vehicle's year, make, and model, set a budget and skill level, and get back a prioritized, opinionated list of exactly which tools to buy — with vehicle-specific notes from an AI trained on real repair data.
No generic "top 10 tool sets" lists. No filler. Every recommendation is tailored to your exact vehicle — because a 2021 Ford F-150 and a 2022 Honda Civic need completely different socket sizes, oil filter wrenches, and specialty tools.

How It Works
Enter your vehicle(s) — Year, make, and model. You can add multiple vehicles if you work on more than one.
Set your budget and skill level — Beginner, intermediate, or advanced. The AI adjusts tool complexity and prioritization accordingly.
Get your tool list — A prioritized build with tier rankings (must-have, recommended, nice-to-have), price estimates, mechanic notes, and links to buy each tool.
What Makes It Different
Vehicle-specific — Tools are recommended based on your exact vehicle's fastener types (metric, SAE, or both), engine layout, and common maintenance needs.
Budget-aware — The AI prioritizes tools by how often you'll actually use them, so you buy the most versatile tools first.
No sponsored rankings — Tool recommendations are based on fit, not paid placement. When we link to Amazon, we earn affiliate commissions, but this never changes what tools are recommended or their priority order.
Who Built This
WrenchSpec is built by Breakglass, a software studio that builds focused, single-purpose tools. Other projects include Origin Recipe (seed oil free recipes from food labels) and DyeFreeCheck (artificial food dye scanner).
