EXIF Metadata

Photos (especially JPEG and HEIC from cameras/phones) often contain EXIF metadata:

  • Capture date and time
  • Camera make and model
  • GPS coordinates (location)
  • Lens information
  • ISO, aperture, shutter speed

This metadata can be used in format patterns with $exif{} placeholders. See Format Patterns & EXIF.

Documents

Format Extensions Extraction Method
PDF .pdf Text extraction; falls back to vision for scanned PDFs
Word (modern) .docx Text extraction via mammoth
Word (legacy) .doc Text extraction via word-extractor
Plain Text .txt Direct UTF-8 reading
Markdown .md Direct UTF-8 reading
CSV .csv Direct UTF-8 reading
Rich Text .rtf RTF tag stripping
OpenDocument .odt XML extraction via jszip

How Documents Are Processed

  1. Text is extracted from the document using format-specific methods
  2. Extracted text is truncated to the text trim limit (default: 4,500 characters)
  3. Truncation strategy:
    • Head only: First N characters (default for most documents)
    • Head + Tail: First N/2 + Last N/2 characters (better for contracts with signatures)
  4. Data-heavy files (lots of numbers) use smaller limits to avoid token overflow
  5. The truncated text is sent to the AI for analysis

Scanned PDFs

If a PDF contains no extractable text (it's a scanned image):

  1. The first page is rendered as an image
  2. The image is sent to the AI's vision capabilities
  3. The AI "reads" the scanned page just like it would analyze a photo

Unsupported Files

Files with unsupported extensions are skipped during drag & drop and folder scanning, and not counted toward batch limits.

Common unsupported formats: video files (.mp4, .mov), audio files (.mp3, .wav), archives (.zip, .rar), executables (.exe, .app).
