# Serif

Serif is a project-wide AI research agent for complete LaTeX projects. It works inside the manuscript, bibliography, figures, supporting files, compiler settings, and finished PDF instead of operating as a separate chat or autocomplete tool.

## Common questions

### Is Serif an Overleaf replacement?

Serif includes the core source-and-PDF workflow of a LaTeX workspace, but its defining capability is a project-wide research agent that can research, edit, create assets, compile, and recover across the complete project.

### Is Serif only for writing prose?

No. Serif can work with sources, citations, project files, editable SVG charts, illustrative images, compiler selection, build repair, PDF inspection, and collaboration.

### Can researchers review or undo agent work?

Yes. Agent activity and file changes remain visible, and history groups edits by Intelligence turn and file so users can inspect or revert the affected work.

### Who is Serif built for?

Serif is built first for doctoral students, researchers, research engineers, and technical authors working on papers, theses, literature reviews, and technical reports in LaTeX.
