Perplexity Pro vs SciSpace
A fellow pulling study characteristics into a table for a systematic review has a clear pick. SciSpace lists data extraction, Systematic Research and search over Google Scholar, PubMed and arXiv, and Premium showed $12 per month billed annually with $20 struck through. Perplexity Pro at $17 per month billed annually sells Deep research, model selection and inline citations, so it is out for that fellow. Every extracted cell still needs checking against the paper, since SciSpace has no published accuracy evaluation. Premium carries 1,200 monthly credits, and unlimited monthly usage starts at Advanced, which showed $70 per month billed annually with $90 struck through under the same sale.
An attending who wants sources behind a clinical question gets Deep research and inline citations from Perplexity Pro. SciSpace is not built for a clinician who needs a referenced answer at the point of care, so that attending gets less from it.
