Use Case Recommendations
Best for: Explainpaper
Explainpaper does one thing: you upload a research paper, highlight the passage that lost you, and it explains that passage in plain language. The interaction model is the point — rather than summarising a paper top to bottom and hoping the summary covers your confusion, it works at the granularity of the sentence or paragraph you actually got stuck on, and lets you ask follow-up questions about the explanation until it lands. That makes it a reading aid rather than a summariser, which is the right shape for anyone who needs to genuinely understand a method section instead of skim its conclusion. Highlight explanations and follow-up questions are unlimited on the free tier, forever, which is unusually generous for the category; the free tier is powered by basic models. The paid tier changes three things that matter for serious reading: advanced models behind the explanations, Math Explain for formulas and figures — the part of a paper where plain-text summarisers are least useful — and whole-paper summaries alongside the passage-level work. Paid also persists your highlights and explanations so a paper you fought through in March is still annotated in June. Zotero library import works on both tiers, so it fits an existing reference workflow rather than asking you to re-upload everything, and a Teams tier adds management, priority support and volume discounts.

- •Teams or individuals who need passage-level explanations triggered by highlighting text
