What our research says

Elicit

Elicit is the only one of these tools that treats a literature review as a structured extraction job rather than a chat, which is exactly right for the work. The price assumes you are billing someone else for the hours it saves.

Pros

  • Column-per-field extraction into a table is the correct shape for review work and rare elsewhere
  • Free tier is unusually generous: unlimited search, summaries and full-text chat
  • Every claim links back to the paper it came from
  • API access is included from the first paid tier rather than sold separately

Cons

  • The $49 to $169 jump is steep and Scale is priced for institutions, not labs
  • Free tier's limits on the Research Agent and Reports are not quantified anywhere on the pricing page
  • Extraction accuracy still needs spot-checking against the source PDF
  • Coverage is paper-centric, so grey literature and preprint-heavy fields are thinner

Petal

The one tool in this space that is a real reference manager first and a document chatbot second, which matters if citations are part of your output. If you only need to interrogate a handful of PDFs, a general assistant does that for free.

Pros

  • Automatic metadata extraction and deduplication removes the worst part of library upkeep
  • Sourced answers link back to the passage rather than paraphrasing without provenance
  • Word add-in and browser importer cover the actual writing workflow, not just reading
  • Paid entry price is a few dollars a month, far below research-AI subscriptions

Cons

  • Free tier's 400 AI credits do not replenish, so it is a trial rather than a usable plan
  • 1 GB of free storage fills fast with scanned PDFs
  • Multi-document chat and AI Create are locked to the Advanced tier and above
  • No API, so it cannot feed a lab's own pipelines

Which one fits

Choose Elicit if you need

  • Researchers screening hundreds of abstracts against defined inclusion criteria
  • Pharma, policy and academic teams that need an auditable trail back to sources

Choose Petal if you need

  • Graduate students and academics managing a growing citation library
  • Literature reviews where answers must be traceable to a specific source passage
  • Small research groups sharing annotated collections with co-authors
