Side Reader is a Chrome extension that opens PDFs in the sidebar of ChatGPT, Claude and DeepSeek so you can read and interact with them side by side: summarize, translate, explain or ask about any passage without leaving the chat.
PDFs render directly in the sidebar next to the chat, so your document and the AI conversation are visible at the same time.
Summarize a whole document, translate it, or have passages explained in simpler terms using the AI you are already signed into.
Built-in buttons cover the common actions, and you can edit their prompts to make the AI respond in the format and tone you need.
Ask about charts, scans or regions that cannot be selected by taking a screenshot question instead.

擅長大量改寫與重寫文字，但在所有應用程式中提供流暢的行內即時校對功能較少。
提供強大的跨應用程式多語言文法與風格檢查，但進階生成式 AI 功能較少。
為網頁、文件、影片與圖片打造的雙語 AI 翻譯
跨裝置的免費 AI PDF 編輯、轉換與閱讀工具
提供更深入的文稿分析與結構報告，但學習曲線比 Grammarly 陡峭。
專項更強Paperpal is an AI writing assistant built for researchers, academics, and students. It proofreads and rewrites academic prose in real time, suggests citations, checks references, and reads PDFs — all from inside Microsoft Word, Google Docs, Overleaf, the Chrome extension, or the web editor.
