–No saved libraries, annotations, or export features
–Last listed update was mid-2024, so the project moves slowly

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

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
