Supported file types

What you can create and edit in Papers AI, what you can add for reference, and what isn't supported yet.

Papers AI picks the editor by file extension. Here's what each type gets you.

Writing and editing

Type	Extension	What you get
Markdown	.md	Prose editor, with a Visual / Code toggle.
MyST	.myst	Scientific markdown, same editor family as Markdown.
Word	.docx	A paginated, Word-style editor with comments, citations, and track changes.
LaTeX	.tex	Source editor with a compile pipeline and PDF preview.
Typst	.typ	Source editor with a compile pipeline and PDF preview.

Data and analysis

Type	Extension	What you get
Notebook	.ipynb	Mixed code and markdown cells, running Python or R in your browser. See Notebooks.
CSV / TSV	.csv, .tsv	A table viewer with sorting, filtering, and in-cell editing.
JSONL	.jsonl	Same table viewer as CSV.
Parquet	.parquet	Recognized, but not yet viewable. Support is coming.
Python	.py	Plain code editor. Typically used alongside a notebook rather than run on its own.

References and planning

Type	Extension	What you get
Bibliography	.bib	Powers citation insertion in Word, LaTeX, and Typst files.
Kanban board	.kanban	A dedicated board view for tracking tasks.
Timeline / Gantt	.timeline	A dedicated board view for planning work across time.

Files you can add, but not edit

Presentation and spreadsheet formats (.pptx, .ppt, .key, .xlsx, .xls) can be added to a project folder (for example when importing an existing folder), but Papers AI can't open or edit them. You'll need a compatible application for those until support is added.

These can live in your project and be attached to the AI, but Papers AI doesn't provide an editor for them:

• PDF (.pdf): opens in a viewer.

• Images (.png, .jpg, .gif, .webp, .svg, and similar): used as figures in your documents.

• Plain text (.txt): opens in a basic text editor, without the formatting tools of the Markdown or Word editors.

Changing a file's format

There's currently no built-in way to convert content between formats (for example, turning a LaTeX document into a Word document). To move content across formats, copy and adapt it manually, or ask the AI to help translate a section from one syntax to another.

You can change which editor a file uses by renaming its extension (for example .md to .typ). Papers AI warns you before applying the change, since it's a different editing pipeline. Renaming only changes which editor opens the file. It doesn't convert or reformat the underlying content, so the result is only useful if the content already matches the new format's syntax.
