Lol Live Helper

LOL Live Helper is a Chrome extension built for watching League of Legends matches. It opens in the browser side panel and gives you quick access to champion, summoner spell, and item information without leaving the stream.

When you see an unfamiliar champion portrait or item icon, use screenshot search to select the target on the current page. The extension matches champions and items locally in your browser, then shows the most relevant results in the side panel.

## Key Features

- Champion lookup: search by champion name, English ID, role tags, and common Chinese nicknames.
- Champion details: view roles, stats, lore snippets, passive ability, and Q/W/E/R ability descriptions.
- Ability videos: play champion ability previews directly in the side panel.
- Summoner spell lookup: check descriptions, cooldowns, ranges, and required summoner levels.
- Item lookup: search items and view prices, stats, effects, tags, and build paths.
- Champion screenshot search: select champion portraits or BP/loading-screen art from a stream to find matching champions.
- Item screenshot search: select a single item or an item strip; the extension can segment the strip and match items.
- Multi-language data: switch between multiple Data Dragon locales in the side panel.
- Local cache: image features are cached in your browser to reduce repeated processing.
