cu1ch3n/papilot is a writing workspace that lets an agent revise LaTeX source based on feedback marked up on a paper PDF. The latest release listed in the repository information is v0.4.0. The provided information does not separately state what was added or changed in this release, so this post looks at the project's features as described in the README. It is built with TypeScript and React and released under the MIT license.
When you select a sentence in the PDF or mark a formula, SyncTeX finds the corresponding LaTeX line at that position and passes it to the agent. The result of the agent's edit can be checked as a before/after comparison of the typeset PDF, and it is not applied to the paper source until the user approves it. Turning the link between PDF annotations and LaTeX revisions into an inspectable step is the core of this tool. The README also describes support for Codex, Claude, and Antigravity agents, a diff view between LaTeX and PDF, PDF annotations, applying selected changes to Git, and per-agent workspaces. The configuration focuses on a flow in which the author reviews the proposed edit and decides whether to apply it.
That said, the README presents no independent evidence of use, such as actual use cases. What can be confirmed at present is the described features and workflow, not the effect on real paper writing. Until independent evidence of use is confirmed, it is more accurate to see this as a working method that connects PDF review with agent edits than as a tool whose editing effectiveness has been validated.
