Saga

Generate a chapter-by-chapter guided tour of a code change as a single, self-contained static HTML page, a saga of your diff. It partitions a diff into ordered chapters that tell one coherent story, each with a plain-language narration and just the hunks that belong to it. Large PRs become easy to review without losing the thread.

The output is one HTML file with everything inlined (diff2html, syntax highlighting, the data). Open it offline, email it, commit it, or drop it on any static host.

Quickstart

cd your-repo
uvx --from saga-cli saga

That runs saga with no install and opens a saga of the current branch against its default base. Using it regularly? uv tool install saga-cli so the command is just saga. See Installation and Usage for the details.
