# SciSpace vs Explainpaper vs Vezz me: choosing the right AI research reading tool.

Compare SciSpace Copilot, Explainpaper, and Vezz me for reading academic papers, STEM equations, and technical documentation.

> **Best fit:** Best fit for graduate students, scientists, and R&D engineers comparing the top three highlight-to-explain tools for research reading.

## Step-by-step workflow

1. **Check where you actually read papers**: Do you upload local PDFs into a cloud vault, or do you read across arXiv HTML, PubMed Central, documentation, and technical blogs in browser tabs?
2. **Compare sidebar vs uploaded viewer vs on-screen overlay**: Explainpaper requires uploading PDFs to its site; SciSpace opens a right-hand sidebar; Vezz me opens a compact overlay right beside the text on any webpage.
3. **Test custom methodology prompts**: Load our Statistical Methods Interpreter preset in Vezz me to audit p-values, confounders, and assumptions on screen.

## How SciSpace, Explainpaper, and Vezz me differ

All three tools share the core insight that highlighting a confusing passage is better than summarizing a whole document—but they serve different surfaces.

- Explainpaper is a web app where you upload PDF files and highlight sentences at preset difficulty levels
- SciSpace is a full academic database (200M+ papers), citation graph, and Chrome sidebar drawer
- Vezz me is a universal on-screen browser overlay that works on any webpage (arXiv HTML, PubMed, GitHub, docs, SEC filings) without a sidebar

## SciSpace vs Explainpaper vs Vezz me

Side-by-side comparison for academic and technical researchers.

| Dimension | Vezz me | SciSpace Copilot | Explainpaper |
| --- | --- | --- | --- |
| Primary surface | Any live webpage (HTML papers, PubMed, GitHub, docs, news) | Academic databases + browser sidebar | Uploaded PDF files inside explainpaper.com |
| Answer placement | Compact floating overlay right next to your selection | Wide right-hand browser sidebar | Right-hand pane inside the PDF reader web app |
| Custom system prompts | Full custom prompts + 1-click JSON preset import/export | Academic preset actions | Fixed difficulty toggles (ELI5, Undergrad, Expert) |
| Browsers | Chrome and Firefox | Chrome / Chromium | Web app (any browser, requires PDF upload) |

## Frequently asked questions

### Which tool is best if my research combines papers AND code/documentation?

Vezz me. Because computer science, biotech, and quantitative finance research moves constantly between papers (arXiv/PubMed) and implementation (GitHub/API docs), Vezz me gives you one seamless shortcut across both.
