Analysis and versions

What analysis produces

When Prescene analyzes a script it builds:

• a profile: logline, summary, tone, and tags
• a scene map: every scene with its beats and story function
• characters and entities: who appears, where, and how they change
• locations and story elements
• page and scene references for everything, so answers cite evidence

This is the intelligence everything else uses: the assistant, coverage, workflows, and version comparison.

Source versions

Every upload is kept as its own version. The title always shows its current analyzed version, and you can open any older version from the version picker. When a new upload is analyzing, the title shows "Analyzing the new version" and switches over when it is done. If an analysis fails, your title stays on the last good version and you can retry. A failed upload never costs you your working state.

Comparing versions

Version comparison shows what actually changed between drafts: scenes added, cut, or rewritten, characters who appear or disappear, and how the story shape moved. Comparison uses scene identity, not raw text, so a scene that moved pages is tracked as the same scene.
