Document Delta Studio

Compare two versions of a document, find what was really added, removed, edited or moved — with every figure change called out — and export a traceable change report.

Everything here runs in your browser. Your documents are not uploaded or sent to any AI service. The only request to this site is loading your own result, if you choose to open one.

This is a deterministic comparison of two Markdown texts. It does not say why anything changed, does not verify the original PDF/DOCX (tables, layout, figures), and is not legal or financial advice. Line numbers are Markdown lines, not PDF pages. Numbers written out in words (for example "three" or 百分之十八) are shown as text changes, not as figure changes.
