Pricing
FreemiumElicit offers a genuinely functional free Basic plan with unlimited paper search, unlimited abstract summaries, and unlimited full-text chat with papers — no credit card required. Research Agent and Research Reports are available with limited usage on the free tier. Plus at $12/month (individual) expands Research Agent runs, Research Report generation, and adds figure extraction from PDFs — designed for independent researchers running regular systematic reviews. Teams at $14/user/month adds collaborative workspaces, shared project libraries, and higher usage limits for research groups and labs. An Enterprise tier is available for institutions requiring SSO, audit logs, higher volume limits, and dedicated support. Note: Elicit significantly lowered its top-tier pricing in April 2026 (from $780 to $79/user/month for the highest plan). Verify current rates at elicit.com/pricing.
FreemiumFree: unlimited basic searches with Sonar, capped Pro Searches (~3-5/day), limited file uploads. Pro: $20/month ($16.67/month billed annually) — unlimited Pro Search, ~20 Deep Research queries/day, model switching across GPT, Claude, Gemini and Sonar, image/video generation, and Comet Plus included. Max: $200/month ($167/month billed annually) — unlimited Deep Research, Perplexity Computer with a large monthly credit pool, Model Council, and priority access to new models. Education Pro: $10/month for verified students via SheerID. Enterprise Pro: $40/seat/month; Enterprise Max: custom pricing (reported around $325/seat/month) with SSO, audit logs, and data-retention controls. The Comet browser is free for everyone. The Sonar API is billed separately, pay-as-you-go by tokens and search-context size.

The answer engine that searches the live web and cites every source
Elicit

Elicit Pros & Cons

Pros

  • Purpose-built for systematic reviews — automates the most time-consuming steps (screening, extraction, synthesis)
  • Structured data extraction with source traceability — every extracted data point links back to its source sentence
  • 138M+ paper database with semantic matching — finds relevant papers based on meaning, not just keywords
  • Free tier is genuinely useful — unlimited search, summaries, and full-text chat with no credit card required
  • Research Agent autonomously searches and synthesizes literature from a single question
  • Zotero integration lets researchers bring existing reference libraries into Elicit workflows
  • Trusted by 2M+ researchers including at top academic and medical institutions globally

Cons

  • Research Agent and Research Reports usage limited on free plan — heavy systematic review users need Plus or Teams
  • Database of 138M papers is strong but not as large as Consensus AI (220M) or Google Scholar
  • Less suited for discovering very recent preprints or non-indexed grey literature
  • No built-in citation manager — relies on Zotero export for reference management
  • Teams and Enterprise pricing is per-user and can add up for large research groups
Perplexity

Perplexity Pros & Cons

Pros

  • Every answer includes transparent, checkable source citations
  • Genuinely useful free tier with no credit card required
  • Model-agnostic: choose the best AI model per query instead of being locked to one
  • Comet browser brings agentic search directly into everyday browsing, and it's free
  • Fast, cited answers for research-heavy and time-sensitive queries

Cons

  • Max tier is a steep 10x price jump from Pro ($20 to $200/month)
  • Citations occasionally don't fully match the underlying claim, requiring manual verification
  • Sonar API pricing is separate from subscriptions and can be harder to budget for
  • Not built for workflow/task automation like CRM updates or ticket handling
  • Weekly/monthly usage caps on some features can be a surprise for heavy users
