Parse emails, PDFs, and documents into structured JSON with LLM-powered extraction
Describe the fields you need in natural language and Airparser extracts them into consistent JSON from PDFs, emails, images, and Office documents.
Forward messages and their attachments to a dedicated address, and Airparser turns each one, plus anything attached, into structured data automatically.
Clean, reshape, enrich, or filter extracted values with Python code, or let the AI code assistant generate it from a plain-language description.
Push parsed records to 7,000+ apps through Zapier, Make, and n8n, or connect directly with REST APIs, webhooks, Google Sheets, Airtable, and Excel.

AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
