Explainpaper
Best overallFor most everyday users who need to quickly understand research papers, Explainpaper wins because its free tier and intuitive interface let you highlight confusing text and get instant plain-English explanations. Paper Digest is faster for getting a high-level summary or audio digest, but its best features are locked behind unclear pricing. The single biggest difference: Explainpaper lets you interact with the paper itself, while Paper Digest gives you a pre-digested summary.

Common questions
Yes, Explainpaper is better because you can highlight specific confusing parts and save explanations to your notebook, which helps you understand and cite papers properly. Paper Digest gives you a quick summary but doesn't let you dig into the details.
Explainpaper has an excellent mobile-responsive website that works in any phone browser. Paper Digest does not advertise mobile support, so it's best used on a desktop or laptop.
Explainpaper has a usable free tier for occasional use, and its Pro plan is $16/month. Paper Digest's pricing is not clearly published, which makes it risky for a casual user who doesn't want surprise charges.
Explainpaper lets you upload PDFs on the free tier (with limits). Paper Digest requires a Pro subscription to upload local PDFs — the free tier only works with DOIs and ArXiv links.
Explainpaper is better because it explains the text you highlight, regardless of field. Paper Digest explicitly misses nuance in legal and humanities papers.
Explainpaper lets you export summaries and notes as Markdown. Paper Digest exports to Markdown, PDF, and JSON, but only if you have access to those features.
Explainpaper wins for everyday users who want to understand papers deeply; Paper Digest is faster for quick summaries but has unclear pricing and weaker mobile support.
If you want to actually understand a research paper — not just skim it — start with Explainpaper's free tier. It's easy, works on your phone, and you'll get real value without paying a cent. Paper Digest is faster for quick overviews, but the hidden pricing makes it a gamble for everyday use.
