Try Wonders for freeWhy look past SciSpace
SciSpace lists a long menu: an agent, Chat with PDF, Literature Review, AI Writer, Find Topics, Paraphraser, Citation Generator, Extract Data and AI Detector. Premium is $20 per month, or $12 billed annually, with 1,200 credits a month. Advanced is $90, or $70 billed annually, with 10,000 credits.
Reasons to look elsewhere depend on which part you used. You may want unlimited use at the entry price. You may want more structure for a thesis. You may need a free plan. Or your institution may restrict AI writing and paraphrasing tools and you want something that has neither.

Wonders
Wonders covers the part of SciSpace that deals with finding, reading and organizing literature, and adds guidance. It suggests keywords and builds Boolean queries with you, and searches Semantic Scholar and OpenAlex, plus Google Patents. It has no index of its own. The reader has highlights, plain-language summaries, term lookup and chat with a paper. Where the full text is available, page-number citations in a summary open the PDF at the passage, and a direct quote is shown only if its words are found in the paper’s text. Sources and notes live on visual boards, and the editor cites in APA, MLA, Chicago, Harvard, IEEE and Vancouver. See features and pricing.
Where it falls short of SciSpace: no systematic review screening or PRISMA workflow, no data extraction tables, no browser extension, no mobile app, no public API, no free plan. It is built for desktop screens. It has no AI writer that drafts text, no paraphrasing tool and no detector either, on purpose. See Wonders vs SciSpace for the full table.
Elicit
Elicit lists unlimited search over 138M+ papers, summaries and chat with papers on its free Basic plan. Paid plans add exports and extraction tables, and Pro at $39 per user per month billed annually adds a systematic review workflow that screens up to 5,000 papers. In our view it is the nearest replacement for SciSpace’s Extract Data and systematic review tools. See Wonders vs Elicit.
Paperguide
Paperguide is the most similar in shape to SciSpace: AI search over 200M+ papers, a reference manager with Zotero and Mendeley import, Chat with PDF, extraction tables, systematic reviews and an AI Paper Writer. Plus is $12 per seat per month billed annually with 12,500 AI credits, and it lists a 30% academic discount. See Wonders vs Paperguide.
Consensus
Consensus answers a research question with a cited synthesis from 220M+ peer-reviewed papers. Free includes 10 Pro messages a month. Pro is $12 per month billed annually, and students and faculty can get up to 40% off. It replaces SciSpace’s literature search and not its reading or writing tools. See Wonders vs Consensus.
