Try Wonders for freeWhy look past Paperguide
Paperguide is a broad product. It lists AI search over 200M+ papers, a reference manager, a research agent, data extraction, a systematic review workflow and an AI writer, with usage metered in monthly AI credits. Its site speaks to evidence teams in pharma, medical devices and consulting as well as to students.
There are a few sensible reasons to look elsewhere. You may want a tool that does one job more deeply. You may prefer a plan without credits. Or you, or your university, may not want a tool that drafts text.

Wonders
Wonders is a guided workspace for the literature review. It suggests keywords, builds Boolean queries with you, and searches Semantic Scholar and OpenAlex, plus Google Patents. It has no index of its own. Ranking uses SCImago journal quartiles for more than 28,000 journals, and you can filter by them. Summaries link each claim to its paper, and a direct quote is shown only if its words are found in the paper’s text. Papers, highlights and notes sit on visual boards, and the writing editor cites in six styles and exports to Word, LaTeX, PDF, BibTeX and RIS. Plus is $20 per month, or $12 billed yearly, with no credits and no cap on searches. See pricing and features.
Where it falls short of Paperguide: no free plan, no systematic review screening or PRISMA workflow, no data extraction tables, no plagiarism checker, no public API. It saves to Zotero but has no Mendeley or EndNote connector. Other libraries come in as .ris, .bib or .nbib files. It also does not generate essays or papers. That one is deliberate, and Don’t cheat explains why. A fuller side-by-side is in Wonders vs Paperguide.
Elicit
Elicit lists search across 138M+ papers and 545,000 clinical trials, research reports, extraction tables, alerts and a systematic review workflow that its home page says supports PRISMA 2020. The free Basic plan includes unlimited search, summaries and chat with papers. Plus is $11 per user per month billed annually. The systematic review workflow sits on Pro at $39. In our view it is the closest match if systematic reviews were your reason for using Paperguide. See Wonders vs Elicit.
Consensus
Consensus describes itself as an AI search engine for research. You ask a question and get a synthesis with citations from 220M+ peer-reviewed papers. The Free plan includes 10 Pro messages and up to 3 Deep reviews a month. Pro is $12 per month billed annually, with unlimited Pro messages and 15 Deep reviews. Its pricing page does not list a reference manager or a writing tool, so it replaces Paperguide’s search and not the rest. See Wonders vs Consensus.
SciSpace
SciSpace lists Chat with PDF, Literature Review, Extract Data, Systematic Research, an AI Writer, a Paraphraser and an AI Detector over 280M+ papers. Premium is $12 per month billed annually with 1,200 credits. Like Paperguide, it meters usage in credits and includes AI writing tools. See Wonders vs SciSpace.
How to choose
This is Wonders’ opinion, not a neutral ranking.
- Systematic review or extraction tables: Elicit, or stay with Paperguide.
- A fast answer with citations: Consensus.
- Many tools, including help with a hard PDF: SciSpace.
- A thesis or literature review, done step by step, with no AI writing: Wonders. Our guide on how to start a literature review shows the workflow it is built around.
Whichever you pick, run the same search in two tools before paying. Index size says little about coverage of your field. If you are new to these tools, academic research tools: a guide for beginners covers the wider set.
