Consensus vs Genspark

Consensus is a search engine built specifically over peer-reviewed scientific literature: ask a question (e.g., "does X improve Y?") and it returns relevant papers with AI-generated summaries of their findings, plus a distinctive "Consensus Meter" that visualizes how much agreement exists across the returned studies — whether the evidence leans toward yes, no, or is mixed. Every summary links to its source paper, making it straightforward to dig into the underlying research. The free tier covers a number of searches and AI summaries per month suitable for casual use; paid plans starting around $9.99/mo raise those limits for students, researchers, and professionals doing more frequent literature searches. Coverage is limited to indexed academic literature, so it won't help with general topics, and the consensus meter is a useful starting signal but can oversimplify genuinely contested or nuanced research questions.

Genspark takes a different approach to AI search: instead of a text answer with links, it generates a custom "Sparkpage" — a one-off web page combining summarized text, relevant images, charts, and citations, assembled specifically to answer your query. Beyond search, it includes a set of built-in agent tools aimed at practical tasks, such as comparing products across shopping sites, planning multi-step travel itineraries, or making automated phone calls on your behalf for simple bookings. The free tier covers everyday search and a limited number of agent-tool uses; paid plans starting around $19.99/mo raise usage limits across both search and agent features. Sparkpage quality depends on how well-covered a topic is online, and as a newer product Genspark has a shorter track record than Perplexity or Google — some of the more novel agent features (like AI phone calls) also raise their own privacy and consent considerations.
