以大模型驅動的文件解析工具，將郵件、PDF 與各類文件轉為結構化 JSON
Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2). It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.

以大模型驅動的文件解析工具，將郵件、PDF 與各類文件轉為結構化 JSON
以自然語言描述所需欄位，Airparser 便能從 PDF、郵件、圖片與 Office 文件中擷取並輸出穩定的 JSON。
把郵件與附件轉寄到專用地址，Airparser 會自動將每封郵件及附件內容轉為結構化資料。
用 Python 程式碼清理、重塑、增補或過濾擷取出的數值，也可請 AI 程式助手依自然語言描述產生程式碼。
透過 Zapier、Make、n8n 將解析結果送到 7,000+ 應用，或經由 REST API、Webhook、Google Sheets、Airtable 與 Excel 直接串接。

It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
