Is the free plan actually usable?

Yes, but limited. You get unlimited highlight explanations and follow-up questions on basic AI models. Advanced models, full-paper summaries, saved highlights, figure/equation explanations, and automatic outlines are gated behind Pro at $16/month.

Does it work on papers outside my field, or in other languages?

Yes. Explanations are adjustable from beginner to expert complexity and available in 50+ languages, so you can read a paper in English while getting the explanation in your native language.

Do I need a credit card for the free tier?

No card is required to sign up and use the free plan. The 7-day Pro trial, however, requires a card on file and will convert to paid billing unless you cancel before the trial ends.

How does it avoid hallucinating answers about the paper?

The chat is scoped to the uploaded paper's content rather than general model knowledge, and it cites specific sections you can jump to. That grounding is what separates it from pasting a paragraph into a generic chatbot.

Which model powers the explanations?

Explainpaper doesn't publicly name its model provider; it tiers access as 'basic AI models' on Free and 'advanced AI models' on Pro. Treat the model identity as opaque and evaluate output quality on your own papers before paying.

Can I integrate it with my reference manager?

Zotero library import is supported on the free tier, so you can pull papers in without re-downloading PDFs. There's no public API or export path for annotations to Markdown or LaTeX, which is the main gap for programmatic workflows.

Single-paper context only; no multi-paper cross-referencing

For technical folks

The deep-dive specs

FAQ

Includes technical Q&A

You upload a PDF research paper, then highlight any sentence that confuses you. The tool sends that passage plus surrounding paper context to a large language model, which returns a simplified explanation. You can then ask follow-up questions about the paper.
