Our content methodology

We focus on three things: symptom-based diagnostics (what does this noise / smell / warning mean?), OBD-II diagnostic trouble codes (generic and manufacturer-specific), and vehicle-specific repair guides indexed by year, make, model, and engine code.

We do not publish content for tasks we do not have structured data for. If a guide is on the site, it is backed by a data package that ties the procedure to verifiable references.

1. A data package is assembled from public technical sources: the NHTSA vehicle and complaint APIs, manufacturer service bulletins, published OBD code references, and aggregated community knowledge (e.g. r/MechanicAdvice). We collect data points — torque specs, part numbers, failure modes, mileage windows — not prose.
2. The package is fed through prompt templates that produce an outline, diagnosis section, tools/parts list, step-by-step procedure, and common-mistakes section.
3. Output is checked against automated quality gates: required torque values present, safety warnings present where applicable, internal links present, schema markup valid.
4. The guide is committed to the site and indexed in our sitemap.

As of the current launch phase, content is generated using Anthropic Claude (via the Claude Code CLI) under a standard subscription. We do not rely on third-party paid APIs for generation; this lets us hold a consistent quality bar without per-article cost pressure.

As the library grows, we will introduce a self-hosted open-weights model for bulk drafting while keeping Claude in the loop for critical / safety-flagged guides. The model used for each guide will be visible in its metadata.

• We do not copy text from forums, manuals, or other guide sites. We collect data; we write the prose.
• We do not invent torque specs, part numbers, or service intervals. If we cannot source it, we do not state it as fact.
• We do not impersonate certified technicians. The editorial team is the publisher of record; no individual repair persona is claimed.
• We do not hide that the content is AI-assisted. Every guide carries this notice at the top.

Guides involving brake systems, airbags, fuel systems, or other high-risk procedures carry an explicit safety warning at the top of the page. If you are not confident in performing a repair, please consult a certified technician. Content here is informational and does not substitute for professional mechanical advice.
