Select AI - Explain & Translate by EndlessGrief

Select AI is a web reading assistant. Select to Explain, Bilingual Translation, YouTube bilingual subtitles, and Image Recognition all stay as close as possible to the page you are reading — less copying, less switching, less waiting, and more staying in the flow.

🤖 Select to Explain — Select a word, phrase, heading, paragraph, or code snippet. Select AI explains what it means in the surrounding page context, not just its literal translation.

🌐 Bilingual Translation — Translate selected page content, or select nothing to translate the whole page. Original text and translation are shown side by side for reading foreign-language webpages and long articles.

🎬 YouTube Bilingual Subtitles — Turn on AI bilingual subtitles with one click when watching foreign-language YouTube videos. It reuses existing video captions, translates them in real time, follows playback progress, and supports adjustable font size.

🖼 Image Recognition — Right-click an image or use Screenshot Recognition to understand charts, UIs, error messages, and text inside images.

📖 Japanese kana ruby for kanji — When reading Japanese content, display kana pronunciation above kanji to help understand unfamiliar words and proper nouns.

🎯 Understands what you selected — Select to Explain judges whether you selected a heading, term, code snippet, or normal text, then switches to the explanation style that fits the reading scenario.

🌊 Shows as it generates — Results appear while AI is generating, so you do not need to wait for the full answer before seeing anything.

⚡ Free AI works out of the box. Bring your own model anytime. — Use the built-in free AI service directly, or connect your own AI service with a custom OpenAI / Anthropic-compatible API.

🔒 Clear permissions and privacy — Select AI reads content only when you actively use a feature, and only the content needed for that task. API Keys are stored only in your local browser.
