PDFs & Citations

Allternit can extract text from PDFs, pass it to models, and surface citations so users can verify answers against source documents.

PDF content blocks

Upload a PDF via /v1/files and reference it in a message:

{
  "type": "pdf",
  "file_id": "file_xxx"
}

Citation format

Responses may include citations arrays:

{
  "citations": [
    {
      "id": "cite_1",
      "document_title": "Annual Report 2026",
      "page_number": 12,
      "passage": "Revenue increased by 34% year over year."
    }
  ]
}

Tool

Use the pdf_process Tool Belt tool to convert PDFs to markdown with structure detection and optional thumbnails.
