# Gear Decision Engine Public Site Summary

Gear Decision Engine is a public research and decision site for camera and creator tech purchases. It is designed to be crawlable, transparent, and source-backed.

## Main entity

- Name: Gear Decision Engine
- Category: camera buying guides, creator tech comparisons, product research, setup tutorials
- Audience: beginners buying gear, serious creators comparing exact products, and shoppers checking used/open-box listings
- Primary verticals at MVP launch: source-backed beginner/creator cameras, creator MacBooks, camera tutorials, YouTube/source radar, eBay exact-match beta

## Recommendation logic

The site ranks products using deterministic JSON rules: category fit, use-case scores, budget fit, priority fit, confidence level, and exact product status. No user-facing live AI chat is used in the MVP.

## First product loop

The core user loop is: buyer inputs category, use cases, budget, skill level, priorities, owned gear, used/open-box tolerance, and risk preference; static scoring returns a best pick, value pick, used/open-box pick when safe, and avoid-for-this-intake item; the site explains the rationale and links to product verdict and comparison URLs that can be copied, saved, shared, or printed without an account.

## Confidence thresholds

- Exact product title match: no required terms missing, no excluded terms, and score >= 78/100.
- Likely product title match: no excluded terms, at most 1 required term missing, and score >= 68/100.
- Hidden match: excluded product terms are present and the item is removed from ranked match output.
- Manual review: weak required terms or used listing price below 65% of expected used minimum.

## Trust implementation

- Product pages include practical creator tradeoffs and setup implications.
- Data models separate product families, exact variants, source evidence, tutorials, and listing confidence.
- Pages cite official sources, trusted reviewers, lab-style sources, and merchant pages with last checked dates.
- Uncertain products and marketplace listings are labeled, not silently promoted.

## Current product coverage

- [Sony FX30](https://geardecision.com/products/sony-fx30): Best first serious cinema camera for solo Sony shooters when photos are secondary and reliability matters more than full-frame look.
- [Sony A7C II](https://geardecision.com/products/sony-a7c-ii): Best compact full-frame hybrid when you want one camera for photos, travel, and polished video without moving to a cinema body.
- [Sony A7 IV](https://geardecision.com/products/sony-a7-iv): Best used hybrid pick if ergonomics, dual slots, and all-around reliability matter more than smallest size.
- [Sony ZV-E1](https://geardecision.com/products/sony-zv-e1): Best compact full-frame video body for casual creators who prioritize size and low light over pro controls and heat margin.
- [Sony A6700](https://geardecision.com/products/sony-a6700): Best value Sony hybrid for creators who want the FX30 sensor family in a smaller photo-friendly body.
- [Canon EOS R50](https://geardecision.com/products/canon-eos-r50): Best entry Canon RF body when you want an approachable first interchangeable-lens camera and do not need pro video controls or long-recording heat margin.
- [Canon EOS R10](https://geardecision.com/products/canon-eos-r10): Best Canon beginner upgrade body when you want to learn manual photo controls and basic creator video without jumping to R7-level cost or weight.
- [Fujifilm X-S20](https://geardecision.com/products/fujifilm-x-s20): Best Fujifilm beginner growth body when you want a stills-friendly camera with creator video headroom and in-body stabilization without jumping to a larger pro body.
- [Nikon Z50II](https://geardecision.com/products/nikon-z50ii): Best Nikon beginner pick when easy stills, travel size, and Z-mount growth matter more than in-body stabilization or advanced video headroom.
- [MacBook Air 13 M4, 16GB, 512GB](https://geardecision.com/products/macbook-air-13-m4-16gb-512gb): Best simple Mac laptop for light creator work, but not the safest choice for heavy DaVinci timelines or long exports.
- [MacBook Pro 14 M4 Pro, 24GB, 512GB](https://geardecision.com/products/macbook-pro-14-m4-pro-24gb-512gb): Best value/default MacBook Pro recommendation for serious creators who do not need the newer M5 Pro configuration or 1TB starting storage.
- [MacBook Pro 14 M5 Pro, 18-core CPU, 20-core GPU, 48GB, 1TB](https://geardecision.com/products/macbook-pro-14-m5-pro-18c-20c-48gb-1tb): Verified current Apple Canada M5 Pro configuration for heavy creator work, but still a cautious higher-cost option until non-Apple workflow evidence is reviewed.

- [How to Shoot S-Log3 on Sony Without Ruining Your Footage](https://geardecision.com/tutorials/how-to-shoot-slog3-on-sony): Use S-Log3 only when you can expose deliberately, monitor your image, and grade or convert the footage later.
