SciSpace

AI research platform for reading, understanding and writing scientific papers

Chat with PDF

Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.

Literature Review and paper search

Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.

Writing, paraphrasing and citations

An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.

Extract Data and AI Detector

Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.

Strengths & Pros

+Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions
+Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work
+Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv

Free tier plus a Chrome extension make it easy to evaluate before paying

Limitations

–Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans
–Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models
–AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity

SOMA

Map the relationships hiding inside biomedical literature

Entity and relationship extraction

SOMA parses published studies and pulls out the factors, exposures and outcomes they discuss, so you can examine the evidence base without reading every paper in full first.

Knowledge graph of biomedical findings

Extracted relationships are organized into a connected graph, letting you start from one condition or factor and follow the links outward to related variables.

Source-linked evidence

Each relationship in the graph is tied back to the studies that reported it, so you can open the source paper and judge the evidence yourself.

Question-driven exploration

Search across study relationships to see which factors have been investigated together and where findings cluster or conflict.

Strengths & Pros

+Turns scattered biomedical findings into an explorable graph
+Cuts the time needed to orient in an unfamiliar research area
+Links relationships back to the underlying source papers
+Focused on open-access literature
+Useful for hypothesis generation across large corpora

Limitations

–Site reliability issues — the public domain was unreachable during our checks
–Coverage is strongest in biomedicine; other research domains are thinner
–Extracted relationships and association graphs are hypotheses, not clinical proof
–You still need domain expertise to interpret links and judge causality
