Graeca - Products Comparison Autor: SouLPouch

Graeca is a local-first Firefox extension that helps you compare products directly from shopping pages.

Select products from a search-results page, review the extracted details, and open a ready-to-paste comparison prompt in ChatGPT, Gemini, or DeepSeek.

## Features

• Detects common product cards automatically, with manual selector and example-card picking when needed.
• Lets you select products directly on the page with checkboxes and keyboard shortcuts.
• Shows data-quality warnings for missing titles, prices, URLs, and model details.
• Offers Fast mode or Specification mode for source-backed product research.
• Ranks the top three options by performance-to-price and reliability-to-price.
• Includes best-for presets such as Gaming, Students, Energy saving, and Budget first.
• Can ask the AI to check whether the same product is cheaper from trusted retailers in your region.
• Saves comparison history locally, with Markdown/CSV export and optional saved AI results.

## Privacy

Graeca has no backend and does not use API keys. Product details, settings, prompts, and comparison history stay in Firefox’s local extension storage.

Graeca opens the AI website you choose and copies the prompt, but it does not automatically submit prompts, sign in to AI services, or send your browsing data to a third-party server.
