The paper and its evidence, in one project.
Write in Markdown or LaTeX beside your sources, datasets, and figures. Every claim links back to the numbers behind it.
Cite as you write.
Keys complete from the project's Sources as you type, in LaTeX or Markdown.
The PDF, beside the source.
Recompile and the paper updates next to the text, with any error pointed at its line.
Figures that know their data.
Datasets keep every version. When the data changes, the figure drawn from it says so, and Regenerate redraws it.

FAQ
Questions.
Do I need to know LaTeX?
No. Write in Markdown and it compiles to a clean paper. LaTeX is there when you want it.
Whose model runs the assistant?
Yours, wherever the assistant is switched on: add a key for Claude, GPT, or Gemini, or let Auto pick. Folie never trains on your drafts; the provider you choose handles your requests under its own terms.
Can my whole lab work in one project?
Yes. Invite your lab to the workspace and everyone works in the same projects. Every version records who saved it, and History shows who changed what. Editing is one person at a time for now.
Can I import my existing draft?
Import a .docx, .md, or .tex file (a Google Doc downloads as .docx), or a whole Overleaf project as a .zip. Export to PDF, to LaTeX, or as a submission package.
