面向 macOS 的本地优先 Markdown 科研工作台
并排双栏阅读器，让 PDF 与 Markdown 编辑器同时呈现，边读边把高亮与批注写入笔记。
从 PDF 元数据生成 BibTeX 或 APA 引用，每条引用都链接回原始高亮，几个月后仍能一键回到出处。
Premium 功能，按含义而非精确关键词检索文献库，由设备端模型驱动，内容不上传。
笔记与文献之间的双向链接构建可视化关系图谱，并可导出为 Neo4j 友好格式。
用于阅读、理解与撰写科学论文的 AI 科研平台
打开或上传论文后直接提问，对高亮段落获取通俗解释，并以对话方式梳理方法、结果与局限性。
在覆盖 Google Scholar、PubMed 和 arXiv 的大型学术索引中检索，并据此生成结构化的文献综述与相关工作章节。
提供起草用的 AI Writer、保持学术语气的改写器，以及支持常见格式的引用生成器。
把论文中的表格与结果整理为结构化数据，并用内置检测器判断稿件是否带有 AI 生成痕迹。
专项更强Offers broad general reasoning and document upload capabilities, but lacks specialized academic indexing and citation databases.
免费 / 开源提供包含引用图表的庞大学术文献免费索引，但缺乏内置的交互式论文阅读助手。
#2专项更强Focuses heavily on assisted academic drafting and autocomplete, whereas SciSpace centers more on reading and analysis.
ResearchRabbit is a free AI research discovery tool that maps the literature around the papers you care about. Seed it with a paper you like and it visualises related work, key authors and emerging topics, learning from your choices to surface the research you have been missing.
Paper Digest is an AI research platform that summarizes literature, generates literature reviews with citations, and delivers daily digests of new papers across arXiv, PubMed, bioRxiv and major conferences. Launched in 2018 and used by millions of researchers, it combines a citation-backed review engine that avoids inventing results with tools for reading PDFs, writing, question answering, claim verification and topic tracking.
Searches academic sources and generates literature reviews, but lacks some of SciSpace's advanced collaborative workspace features.
专项更强Condenses papers into structured summaries quickly, but lacks SciSpace's full interactive research workspace and citation management.
