Research PDFs aren't small. Between high-resolution figures, long appendices, and dense tables, it's easy to end up with a file that traditional upload flows simply reject. Starting today, ResearchCast supports PDF uploads up to 100MB - so you can turn the entire paper into an accurate, grounded-in-paper podcast you can listen to anywhere.

If you've been looking for a reliable PDF to podcast workflow - an AI podcast generator that actually reads and understands the paper first instead of rephrasing an abstract - ResearchCast is for you.

Why 100MB matters for academic PDFs

A surprising number of important papers ship as "heavy" PDFs: conference camera-ready versions, dissertations, long-form surveys, or papers with many figures. Some are small in page count but huge in bytes because of embedded images.

  • Fewer workarounds: No more re-exporting, compressing, or stripping figures just to get a paper through an upload form.
  • Better fidelity: Keeping the original PDF intact helps us interpret results, tables, and figure captions in context.
  • More papers supported: Large PDFs are common in ML, medicine, and systems work - exactly where listening can save hours.

Full-paper processing for more accurate, grounded podcasts

The real upgrade isn't only the file size limit - it's what we do with the PDF once it's uploaded. ResearchCast is designed to generate a research paper podcast that stays grounded in the source document.

That means we process the full paper to capture the parts that actually matter:

  • Methods and experimental setup: What the authors did, what baselines they compared against, and what evaluation they used.
  • Results with quantitative detail: Key numbers, metrics, and comparisons that make conclusions trustworthy.
  • Figures and tables: What the important plots and tables show (and why they support the claims).
  • Limitations and caveats: Where the paper is strong - and where the authors themselves draw boundaries.

In practice, this is what makes the difference between a generic "paper summary podcast" and an academic paper to audio experience you can actually rely on.

Turn a PDF into a podcast in minutes

To generate a scientific paper podcast from your own PDF, upload your file (up to 100MB), pick a format, and hit generate.

  • Overview: A fast 2-3 minute scan to decide whether the paper is worth deeper time.
  • Deep Dive: A guided walkthrough that covers the paper step by step, including methods, results, and limitations.
  • Lunch Talk, Debate, ELI5: Alternative formats when you want a different learning style.

If you're searching for an AI podcast generator for research papers or a simple way to turn PDFs into podcasts, this is the most direct flow we've shipped yet.
