## What it is
A browser extension that parses competitive programming problems from online judges like Codeforces, AtCoder, and Kattis. It extracts test cases and constraints and sends them to local tools such as CP Editor, CPH, and various editor plugins.

## Use cases
- scrape test cases from codeforces problems into my editor
- parse atcoder contest problems automatically
- download sample testcases from online judges
- send competitive programming problems to cp editor
- extract problem constraints and examples from kattis
- automate fetching icpc contest problems locally

## When to choose
- you solve problems on supported online judges and want test cases loaded into a local editor or helper tool automatically
- you use CP Editor, CPH, acmX, or similar tools that integrate with Competitive Companion

## When to avoid
- you need a general-purpose web scraper rather than competitive programming problem parsing
- your online judge is not among the supported sites

## Facets
- artifact type: plugin
- maturity: active
- function: parser, web-scraping, browser-extension
- domain: developer-tools, web-development
- platform: browser, browser-extension, cross-platform
