"LockTrans" is a free browser extension created specifically to solve this issue. Its primary goal is to let you forcibly translate text into your desired language with a single click, complete with audio pronunciation. [How to Use] Click the "Extensions" icon in your browser to pin "LockTrans". Click "LockTrans" to select your source and target languages (an illustrated guide opens on first run). Trigger translation (mix & match from 3 methods): ・Highlight text → Release mouse → Press Shift ・Highlight text → Click the floating LockTrans icon ・Highlight text → Right-click → Select "LockTrans Translate" The translation and pronunciation guide appear right below the selected text without breaking your reading flow. [Key Features] ✦ 3-way translation between Japanese, Chinese and English; multiple target languages at once ✦ Uses Google Translate by default; optionally connect your own AI model (bring your own API key) for context-aware translation ✦ AI mode can include surrounding text and a glossary of names/titles ✦ Click the language label at the top of the popup to switch input/output languages instantly ✦ Auto-read the source text with Play / Pause / Stop / Replay ✦ Romanization (Romaji / Pinyin) ✦ Draggable, pinnable popup with independent scrolling for long text ✦ Light / dark themes; UI in Traditional Chinese, English and Japanese ✦ Settings are saved automatically [Privacy] ・Default mode: the text you select is sent to the public Google Translate service to get the translation and audio. No account is required. ・AI mode (optional): only after you enable it and enter your own API key, the selected text (plus ~200 characters of surrounding text if "Include surrounding text" is on) and your glossary are sent directly to the AI service you configured. The API key is stored only in your browser, is not synced, and is never sent to the developer. Each AI provider handles data under its own policy (for example, free tiers may use content to improve models) — please check it and avoid confidential text. ・The developer runs no servers and does not collect, store or sell personal data. There is no analytics or tracking. 日本語 テキストを選択して Shift を押すだけで、即座に翻訳して読み上げます。日本語・中国語・英語に対応し、AI モデルを接続してより正確に翻訳することもできます。 更新履歴 v6.0.2 メジャーアップデート ・AI モデル翻訳を追加:ご自身の API キーを使用(Google Gemini、DeepSeek、Groq、OpenRouter、Ollama など OpenAI 互換サービスに対応) ・AI 翻訳は前後の文脈を参照し、主語の省略・慣用句 ・二重否定の誤訳を軽減。人名・作品名の対訳表にも対応 ・翻訳ウィンドウ上部の言語表示をクリックして、入力/出力言語を即時切り替え・再翻訳 ・ライト/ダークテーマを追加(初期値はライト)、設定画面を 2 カラムの横長レイアウトに変更 ・初回起動時の図解ガイド(繁体字中国語/English/日本語)を追加。設定画面からいつでも再表示可能 ・再生/停止ボタンのサイズを統一し、重複していた「もう一度読み上げ」ボタンを削除 ・AI のリクエストが失敗した場合は Google 翻訳へ自動で切り替え、通知を表示 v5.31 翻訳トリガーが動作しない問題を修正 v5.28 3言語(繁体字中国語/English/日本語)UI切り替え機能を追加、設定画面のテキストを太字・ハイライト化 v5.27 選択テキストのフローティングアイコンおよび右クリック翻訳機能を追加、トリガー方法の設定機能を追加、音声再生終了後の再生成に対応、英語のテキスト切れ問題を修正 v5.05…
