Our Verdict
Both answer research questions with sources, but they search different places. Perplexity searches the web and, on Pro, premium sources such as PitchBook and Statista. SciSpace works with academic papers: Deep Research, Chat with PDF and literature reviews. Choose Perplexity for market research, competitor scans and client prep. The free plan includes citations in every answer, and Pro is $20/mo or $200/yr (about $17/mo) with deep research and a choice of top AI models. Choose SciSpace if peer-reviewed studies are part of your deliverable, as in healthcare, biotech, education or policy work. Premium is $12/mo billed annually ($20 monthly) with 1,200 monthly credits, Deep Research and unlimited Chat with PDF. Advanced is $70/mo billed annually ($90 monthly) for unlimited monthly usage. The pricing page lists no free plan, but every plan has a 24-hour money-back guarantee. If your sources are mostly news, company websites and industry data, Perplexity covers it. If you read and cite papers every week, SciSpace is the cheaper paid plan and is built for that job.
