Review how experiment changes affect an existing research paper. PaperDelta connects declared CSV/JSON evidence to numbers, comparisons and figure provenance in LaTeX and optional Word/PDF manuscripts, then shows affected locations in an offline report.

Install with Python 3.11 or newer in a virtual environment:

python -m pip install paperdelta
paperdelta demo --out paperdelta-demo --open

The complete original demo ships in the core package. No model key, GPU, TeX, checkout or plotting dependency is required. The changed scenario intentionally reports outdated numbers and a false claim; the demo creates files but does not apply paper edits. Every run uses a new output directory.

Batch binding, explicit review scopes, traceable exclusions and file watching support repeated review. Reports and CLI prompts support English and Chinese. Verified numeric edits have a preview and recovery journal. Seventeen optional MCP tools are available through python -m pip install 'paperdelta[mcp]'.

Optional Word review: install paperdelta[docx] and run paperdelta demo --document docx --out word-demo --open. Paragraphs and ordinary tables use native positions; Word files are read-only and unsupported structures remain explicit.

Checks cover declared evidence and supported LaTeX/Word/PDF structures. They do not certify scientific truth or infer a correct mapping from matching numbers alone. The original implementation is MIT licensed; separately licensed paper evaluation sources are excluded from the Python distributions.

检查实验结果变化影响了现有论文的哪些位置。PaperDelta 将明确声明的 CSV/JSON 证据关联到 LaTeX 及可选 Word/PDF 稿件中的数字、比较和图表来源，在离线报告中集中展示待复核内容。

使用 Python 3.11 以上版本，在虚拟环境安装：

python -m pip install paperdelta
paperdelta --lang zh-CN demo --out paperdelta-demo --open

核心包自带完整原创演示，无需模型密钥、GPU、TeX、源码仓库或绘图依赖。变化场景 会有意检出旧数字和失效结论；演示创建文件，不自动修改论文，每次需使用新输出目录。

批量绑定、明确审查范围、可追踪排除和文件监听支持持续使用。报告及命令行支持 中英文；验证后的数值修改可预览并通过事务恢复。安装 python -m pip install 'paperdelta[mcp]' 可使用十七个可选 MCP 工具。

可选 Word 检查：安装 paperdelta[docx] 后运行 paperdelta --lang zh-CN demo --document docx --out word-demo --open。 段落和普通表格使用原生位置；Word 文件保持只读，不支持的结构会明确报告。

检查限于已声明证据和受支持的 LaTeX/Word/PDF 结构，不认证科学正确性，也不以数字相同证明 映射正确。原创实现采用 MIT 许可；单独许可的论文评测源码不包含在 Python 发行包中。

PDF and shared manuscripts / PDF 与多稿件

Install paperdelta[pdf] and run paperdelta demo --document pdf --out pdf-demo --open. Original-page highlights, explicit source/export comparisons and shared metrics help find a corrected source whose exported PDF is stale. PDF is read-only; scans and unreliable content remain unverified. No OCR is performed.

安装 paperdelta[pdf] 后运行 paperdelta --lang zh-CN demo --document pdf --out pdf-demo --open。 原页高亮、明确的源稿/导出稿比较和共享指标，可以帮助发现源稿已更新但 PDF 仍过期的 问题。PDF 保持只读；扫描件及不可靠内容不参与验证，不进行 OCR。
