The honest brief

SciSpace

Search, PDF Q&A, and agentic literature review sit in one academic workspace, against a larger paper index than most rivals query.

  • 280M+ paper corpus
  • Agentic Deep Review search
  • Cited answers over PDFs
  • Writing aids (paraphrase, citations)
  • Undisclosed underlying models
  • Free tier limits depth
  • Answer quality varies by field

Semantic Scholar

A free, nonprofit-run corpus of 200M+ papers with auto-generated TLDR summaries and an open API — no paywall or ads, unlike most research tools.

  • TLDR one-sentence summaries for many papers
  • Covers every field of science
  • Semantic Reader adds inline citation context
  • Adaptive Research Feeds for new work
  • TLDR coverage skews to CS, bio, and medicine
  • Not a chat/Q&A research assistant
  • Metadata gaps for some niche fields
