Chess move advice and position evaluation assistant for Lichess.org

Helps Lichess players get real-time move suggestions and position evaluation scores during active games, and allows analysis of specific chess positions via FEN strings.

User installs extension -> Opens Lichess.org and starts a game -> Right-clicks to open side panel or clicks extension icon -> Clicks 'Move Advice' button -> Extension fetches current game URL, sends FEN to external Stockfish API -> API returns best move and evaluation -> Extension displays move and highlights it on the board.

Target users: Lichess.org players / Chess enthusiasts looking for move analysis

The extension relies on an external, unofficial Stockfish API (stockfishapi-jh4a3z47hq-uk.a.run.app). The stability and privacy of this third-party service are not guaranteed.
The extension does not verify the Lichess game state directly via Lichess API but likely parses the DOM or relies on the content script to inject into the page. The code suggests it queries the tab URL and potentially the content script interacts with the page to get the board state, though the exact mechanism for extracting the FEN from the live Lichess page is not fully visible in the provided snippets (likely handled by content-script.js or injected scripts).
The 'Buy Me a Coffee' link suggests the developer relies on donations, but this does not constitute a paid feature.

Monetization

No paid features detected

The extension appears to be completely free. There are no references to subscriptions, payments, premium tiers, or license keys within the extension code. The 'pro' keyword matches in the static analysis were false positives (e.g., 'profile', 'promotion', 'hasOwnProperty'). The extension uses a free external API (stockfishapi-jh4a3z47hq-uk.a.run.app) for move suggestions and evaluation. The only monetization signal is a 'Buy Me a Coffee' link in the support page, which is a voluntary donation mechanism, not a paid feature gate.

Reason: The extension is an assistant for Lichess.org. The core workflow involves analyzing active games on lichess.org. The extension detects if the current URL includes 'lichess' to function (script.js:39). While the extension itself does not implement a login UI, the destination service (Lichess) requires an account to play games and access the board state that the extension analyzes. The extension relies on the user being logged into Lichess to have an active game to analyze.
