What our research says

AnswerThis

AnswerThis goes further into the actual review process than most cited-answer tools — dual-reviewer screening, evidence grading and PRISMA structure are real workflow features, not chat wrappers. The catch is price: $35 a seat is well above general research assistants, and the free tier's five-project cap makes a serious evaluation awkward.

Pros

  • Screening, evidence grading and drafting sit in one workflow
  • Free plan needs no card and still includes cited search and exports
  • Exports into standard reference managers and thousands of citation styles
  • Institutional tier covers SSO and LMS integration rather than just more seats

Cons

  • Corpus size is stated inconsistently: 300M+ papers on the homepage, 250M+ on the pricing page
  • Team tier requires three seats billed annually, so the real entry cost is much higher
  • No API for pulling results into other tools

Undermind

The search actually reads papers rather than matching keywords, which is why it surfaces work that keyword ranking buries. Runs are slow by design and the free tier's rate limits bite quickly, so it earns its keep only if literature review is a regular part of your week.

Pros

  • Reports how completely it covered a topic, not just a result list
  • Follows citation trails automatically
  • Alerts when new relevant papers appear
  • MCP connection lets Claude or ChatGPT run searches through it

Cons

  • Deep searches take minutes rather than seconds
  • Free tier rate limits are tight
  • No documented public REST API, only the MCP connector
