Common questions
No, Petal is better. You'll need to cite sources, and Petal's automatic citation extraction and multi-paper search will save you far more time than Explainpaper's single-paper explanations.
Both work in a mobile browser, but Explainpaper's interface is much more polished for reading and highlighting on a small screen. Petal's mobile experience is usable for searching but not for editing PDFs.
Petal. Its free tier supports more file types and more documents per month. Explainpaper's free tier is very limited and will frustrate anyone reading more than a couple papers.
Yes, both work with any PDF. Explainpaper is best for dense technical documents, while Petal is better for managing a collection of reports and extracting key data across them.
Explainpaper. You upload a PDF, highlight a sentence, and get an explanation in seconds. Petal requires you to set up collections and sync your library first.
Explainpaper is the easiest way to understand a single paper; Petal is the better value for anyone managing a research library.
If you just need to understand a handful of papers without any fuss, start with Explainpaper's free tier. But if you're a student or researcher who reads regularly and needs to keep track of citations, Petal's generous free tier and superior library management make it the smarter long-term choice.
