Research Paper to Text — FAQ

Converts research papers — arXiv preprints, journal articles, theses — into clean LaTeX-formatted plain text optimized for math + citations. Equations come back as `$...$` LaTeX, multi-column layouts get unwound, references preserved. Faster + smarter than copy-pasting a PDF into a text editor.

Generic PDF tools like pdftotext destroy equations and scramble multi-column reading order — fine for memos, useless for papers. Nougat (the model behind Research Paper to Text) was trained on millions of arXiv pages specifically to handle that case.

PDF only right now — born-digital and scanned both work. Max 50 MB. Most research papers are ≤10 MB so this isn't a constraint in practice.

Nougat outputs LaTeX-flavored Markdown — inline equations as `$...$`, displayed as `$$...$$`. Drop the output into Pandoc / Quarto / a Jupyter notebook and equations render natively. Or feed it to ChatGPT and ask for a plain-English explanation of each equation.

Yes — automatic. Two-column IEEE-style and three-column journal layouts both come out as a single readable text stream in proper reading order.

Tables are extracted into Markdown table syntax. Figure captions are preserved; figure images themselves are not extracted (we keep just the text + math).

Inline citation markers stay where they are. The references / bibliography section at the end is extracted intact so you can use it with Zotero, BibTeX, or your own pipeline.

Roughly 8-15 sec/page. 300 tokens/page (floor 600). A 10-page paper = 3K tokens; daily free pool covers a few papers per day for signed-in users.

PDFs are processed immediately and deleted. Output is kept 24h (anonymous) / 7 days (paid). Never used for training.

Yes — clean LaTeX output is ideal for downstream LLM ingestion. Many users build paper-search engines or "explain this paper" bots on top of this endpoint.

GROBID is excellent for citation extraction but weak on math. SciPDF is heavier to deploy. Nougat is purpose-built for the full PDF→text+math conversion in one pass — best for end-users who just want the paper as readable text.

Yes — same /v1/document/academic-pdf/ endpoint. Multipart `file` upload, JSON response, Bearer auth. /api/ for the curl example.
