Chrome · PDF 0.9.2 · Interactive paper reading

LLM_in_PDF 帮你在 Chrome 中阅读本地 PDF 和 arXiv 等平台的论文，交互式调用本机 Claude Code、Codex，选择局部文字、图表或公式进行问答与追问。

LLM_in_PDF helps you read local PDFs and papers from arXiv and other platforms in Chrome, interactively using your local Claude Code or Codex agent for questions about selected passages, figures and formulas.

PDF 0.9.2 updates the English/Chinese READMEs, store descriptions, popup and promotional copy. Runtime behavior, permissions and data flow are unchanged. Overleaf remains 0.9.1. This GitHub release is a publication kit; it is not a Chrome Web Store submission or approval.

• Upload LLM_in_PDF-0.9.2-chrome.zip or LLM_in_Overleaf-0.9.1-chrome.zip to the matching store item.
• The matching *-companion.zip contains the local bridge. Node and a signed-in local CLI are required; use the actual store extension ID in the install command.
• LLM_in_Work-chrome-store-materials-0.9.2.zip contains the updated bilingual copy, images, disclosures and reviewer steps.
• package-report.json and SHA256SUMS.txt cover the runtime bundles.

The updated packages passed resource/metadata checks and isolated Chromium loading, PDF import/render/text/reload, companion installation, exact-ID authorization, native ping and uninstall checks.

Chrome 0.9.1 · Publication packages and store materials

Bring the Claude Code or Codex agent already installed on your computer into everyday workflows: select precise passages or figures, review changes, and ask questions in place.

Chrome publication preparation for LLM_in_Overleaf 0.9.1 and LLM_in_PDF 0.9.1. These packages have not been submitted to the Chrome Web Store in this release.

• Upload LLM_in_Overleaf-0.9.1-chrome.zip and LLM_in_PDF-0.9.1-chrome.zip to their respective Chrome developer dashboard items.
• Give users the matching *-companion.zip for the local bridge. Node and a signed-in Claude Code or Codex CLI are still required. Use the actual store extension ID when installing; popups display the right command.
• LLM_in_Work-chrome-store-materials-0.9.1.zip includes English/Chinese listings, real-model screenshots, promotional graphics, permission explanations, privacy policy and reviewer steps.
• package-report.json and SHA256SUMS.txt describe and verify the runtime bundles.

Overleaf supports selected LaTeX edits with diff review and explicit application. PDF connects the local agent to selected-text and cropped-image questions in Chrome, leaving the PDF unchanged. PDF currently has a Chinese interface; its Windows setup uses the HTTP companion.

Validation: Overleaf 38 unit tests, installer and browser suites; PDF 19 tests and both browser suites; real Claude screenshot captures; actual ZIP loading, every packaged resource, PDF import/render/reload, companion installation, exact-ID authorization, native ping and uninstall in temporary profiles/homes.

Cross-platform CI: all 15 jobs passed, including Windows/macOS/Linux and the Linux tests against the built ZIPs.

“Just this paragraph.” — a new story edit

A draft is nearly due. You want to improve one paragraph, but first you have to explain where it is. What if you could simply point to it?

The new introduction follows that small problem through selection, review and confirmation. Live-action close-ups and a moving three-panel sequence show the answer; the closing returns to the opening paragraph.

• Fresh, warm female narration in both Chinese and English, with conversational phrasing and deliberate pauses.
• Moving application windows, operation close-ups, animated scenario bubbles, a connection diagram and a closing montage.
• A quiet original instrumental score that ducks under speech.
• Bilingual subtitles, inline 720p playback, downloadable 1080p videos and reusable caption-free source clips.

The product order remains Word → Overleaf → Chrome PDF → PowerPoint → Excel. PDF questions leave the original file unchanged. Narration is synthesized; demonstrations use real recordings, with shortened waits. Overleaf is shown on a local demo page running the real extension.

60 seconds: your local agent, wired into your work

A short introduction to LLM_in_Work. The Claude Code or Codex already signed in on your computer works inside Word, Overleaf, PowerPoint, Excel and the papers you read in Chrome: select exactly what you mean, change only that part, and decide what gets applied.

2026-10-08 · Precise control inside your everyday apps

Precise control inside your everyday apps

Claude Code and Codex can already edit documents and read PDFs. LLM_in_Work connects those locally installed, signed-in agents to the apps where you work, so you can select an exact target, review the proposed change, and confirm what to apply in place.

This presentation update puts that motivation first in both READMEs and the narrated videos. The demos now follow Word → Overleaf → Chrome PDF → PowerPoint → Excel. The PDF introduction describes using a local agent with PDFs in Chrome: select text or crop a figure and ask beside the document. PDF content stays unchanged.

2026-10-07 · LLM_in_PDF 0.9.0 · Five assistants

LLM_in_PDF 0.9.0 joins LLM_in_Work

paper_read is now LLM_in_PDF, alongside Word, PowerPoint, Excel and Overleaf.

• Read online/local PDFs and paper webpages. Ask about selected passages or cropped figures, with the full extracted text as context.
• Render Markdown tables, code and math; save per-document conversations and copy current/all history.
• Keep the existing extension ID, conversation data and PAPER_READ_* settings compatible. New settings use LLM_IN_PDF_*.
• Install the native bridge on macOS/Linux with cd LLM_in_PDF && ./install.sh. Windows uses npm start and the HTTP fallback.
• Both language READMEs, security documentation and CI now include the PDF assistant. No private extension signing key is included.

New narrated videos

The attached English and Chinese videos cover all five assistants, with bilingual captions and separate SRT subtitles. Each language has a full 1080p file and a compact 720p version.

LLM_in_PowerPoint 0.1.0 (new)

• Add selected words, a text box, a table, a group or a whole slide as targets (up to 16, across slides); each gets its own diff.
• Only the changed words are written, so bold figures, colours, bullet levels and line breaks keep their formatting. Every applied card has a one-click Undo.
• Tables change cell by cell and can gain or lose rows. Slide image lets the model see the slide; Presentation Q&A drafts speaker notes and checks consistency.

Install: cd LLM_in_PowerPoint && ./install.sh (Windows: install.ps1), then restart PowerPoint.

LLM_in_Excel 0.1.0 (new)

• Add one or several ranges (Cmd/Ctrl multi-select), including an empty column to fill. Sheets travel as tables with row numbers and column letters, so replies list only the cells that change.
• The cell preview strikes through each old value. Cells are written as if typed and only when they change: number formats stay, IDs like 00123 stay text, and a blank cell in a reply never erases anything. Undo restores values, types and number formats.
• Workbook Q&A summarizes, finds problems, explains formulas and suggests charts, citing cell addresses.

Install: cd LLM_in_Excel && ./install.sh (Windows: install.ps1), then restart Excel.

Both run as local services next to LLM_in_Word (ports 8387 and 8397). On macOS they reuse an already trusted localhost certificate, so no second password prompt.

中文摘要

• PowerPoint 0.1.0（新增）：可以把选中的字词、文本框、表格、分组或整页加为目标（最多 16 处，可跨页），每处一份差异；只改动有变化的字词，加粗数字、颜色、要点层级和段内换行保持原样，每张卡片可一键撤销。表格按单元格修改、可增删行；可附当前页截图；演示文稿问答可写讲稿、查一致性。
• Excel 0.1.0（新增）：可以添加一块或几块区域（按住 Cmd/Ctrl 多选），也可以是要填写的空白列；工作表以带行号、列字母的表格发给模型，回复只列有变化的单元格。预览划掉旧值；写入和手动输入一样，只写有变化的格子，数字格式不变，00123 这样的编号仍是文本，回复里留空的格子不会清掉任何内容；撤销会恢复值、类型和数字格式。表格问答可总结、找问题、解释公式、推荐图表，回答注明单元格地址。
• 安装：分别在 LLM_in_PowerPoint、LLM_in_Excel 目录运行 ./install.sh（Windows 用 install.ps1），再重启 PowerPoint / Excel。macOS 上会沿用已信任的本机证书，不用再输密码。
• 文档：首页改为介绍四个助手；演示视频新增 PowerPoint 和 Excel 两段。

LLM_in_Overleaf 0.9.0

• Full English interface with a live English / 中文 switch in the panel and the popup.
• Explanations follow the language of your instruction; replacements keep the document's language.

• Request timeouts, clean stop, and clearer errors with a suggested fix.
• Markdown tables in replies render as tables.
• New installers: install.ps1 for Windows and Linux support in install.sh, both with an uninstall option.

Update: rerun the installer, click Reload on the extension card, then refresh Overleaf.

LLM_in_Word 0.7.1

• Explanations follow the language of your instruction (previously always Chinese).
• Table edits match rows by content: inserting or deleting a row in the middle changes only that row.
• The Writing engine section folds into a one-line summary, leaving about twice the room for results.
• Connection hints follow the interface language; Markdown tables render as tables.

Update: git pull, then npm run update in LLM_in_Word.

中文摘要

• Overleaf 0.9.0：新增英文界面与中英切换；说明文字跟随指令语言；Claude 调用更安全（不加载本机 MCP、不开放额外工具）；增加超时和出错建议；回答里的表格正常显示；新增 Windows / Linux 安装与卸载。
• Word 0.7.1：说明文字跟随指令语言；表格中间插入或删除一行只改这一行；写作引擎设置可折叠，结果区域约大一倍；连接提示跟随界面语言。
• 文档：重做中英文首页，附中英文讲解的演示视频和新截图。
