Google Geminiが意味を要約し、吹き出しでその場に表示 ■ 主な特長 ・キーボードとマウス操作だけで完結、コピペや別タブでの検索が不要 ・Gemini 3.1 Flash-Lite を優先的に使用し、高速な応答を実現 ・複数のGeminiモデルへの自動フォールバックにより、無料枠のクォータ超過時も安定動作 ・ブラウザの表示言語を自動検出し、日本語・英語・中国語など設定言語に応じた説明文を生成 ・説明文は画面外にはみ出さないよう自動で表示位置を調整 ■ 必要なもの Google AI Studio などで取得できる無料のGemini APIキーが必要です。 取得したAPIキーは、拡張機能の設定画面からご自身の端末に保存され、Google Gemini APIへの問い合わせにのみ使用されます。 (APIキーや選択テキストが開発者のサーバーに送信されることはありません) ■ こんな方におすすめ ・専門用語の多い記事やドキュメントを読む方 ・英語や他言語のページを読みながら単語の意味を確認したい方 ・ページを離れずに素早く言葉の意味を確認したい方
