PaperDemo — interactive supplements that publish alongside your arXiv paper

A publishing tool that lets authors attach one or more LLM-generated interactive widgets to their arXiv or blog post, with version pinning so reviewers see the same demo you submitted.

Target user

academic researchers and graduate students publishing technical papers

Features
  • Submit a theorem statement and get a draft visualization plus counterexample explorer
  • arXiv-compatible sidebar embed that does not require reader accounts
  • Reviewer-locked preview links so the same demo is reproducible across revisions
  • Citation-ready widgets that count as 'supplemental material' in CVs and grant reports
Why now

Tao explicitly said he plans to ship interactive visualizations as supplements for future papers — a hosted 'paper-demo' service tied to arXiv would standardize what Tao just invented by hand.

Demand
5/10

Terry Tao explicitly stated intent to attach LLM-built interactive visualizations as paper supplements, validating the use case at the top of academia; broader demand exists across the ~2.4M arXiv corpus but currently concentrated in ML/data-viz communities using ad-hoc Jupyter/Colab.Old and new apps, via modern coding agents | What's newarXiv.org e-Print archive

Whitespace
6/10

No product standardizes 'interactive supplements tied to arXiv submissions with version pinning'; adjacent platforms (Hugging Face Spaces, Papers With Code, Observable) serve overlapping but distinct needs (model hosting, reproducibility, notebooks) without the arXiv-anchored widget framing.Paper page - Computational reproducibility of Jupyter notebooks from ...Pricing - Hugging Face

Monetization
3/10

Academic researchers rarely pay out-of-pocket; competing free tiers from HF ($0 public) and existing free notebook hosting make paid conversion hard. Likely needs institutional/grant-funded B2B or grant-piggyback model.Hugging Face Pricing 2026: Free, PRO & Team Plans from $9/mo

Longevity
7/10

Interactive/reproducible-paper trend is durable and well-established (Distill.pub ~2017, Papers With Code ~2018, Jupyter reproducibility studies); LLM-generated widgets are a natural next step rather than a fad.Understanding and improving the quality and reproducibility of Jupyter ...

Feasibility
6/10

Buildable on existing widget runtimes (Streamlit, Gradio, Observable) with arXiv ID + git hash pinning; main work is the authoring UX and LLM-code-sandboxing safety layer, not the hosting infra.Old and new apps, via modern coding agents | What's new
