PubMinder is an AI-powered research feed for scientists, students, and curious minds. It aggregates the latest preprints and journal articles from bioRxiv, medRxiv, arXiv, and PubMed — then summarizes each one in 2–3 plain-English sentences using Apple Intelligence (on-device) or Groq's free AI. WHAT IT DOES Fetches the newest papers from the subjects you care about Summarizes every abstract automatically — no reading walls of text Opens papers in a built-in reader, so you never lose your place Lets you save and share papers with one tap Search your saved papers and sort by date, title, or source Supports keyword filtering so only relevant papers reach your feed ORGANIZE YOUR LIBRARY (PRO) Add tags and notes to any saved paper Group papers into collections and browse by project Export your library to BibTeX, RIS, or CSV — import straight into Zotero, EndNote, or Mendeley, with authors, year, and journal included SOURCES INCLUDED bioRxiv — biology and life sciences preprints medRxiv — medical and clinical preprints arXiv — physics, mathematics, and computer science preprints PubMed — peer-reviewed journal articles via NCBI E-utilities AI SUMMARIZATION On Apple Intelligence-capable devices (A17 Pro, A18, or M-series chips, iOS 26+), summaries run entirely on-device — no internet, no API key needed.

Verdict
The clearest difference is ads: PubMinder at none against Logical Argumentation's shown. Logical Argumentation's advantage is update cadence (every 3 weeks vs every 5 weeks) and iOS requirement (15.6 vs 18.0). On price, in-app purchases and device support there is nothing between them.
