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.

|---|---|---|
.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 |

How Documents Are Processed
- Text is extracted from the document using format-specific methods
- Extracted text is truncated to the text trim limit (default: 4,500 characters)
- 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)
- Data-heavy files (lots of numbers) use smaller limits to avoid token overflow
- The truncated text is sent to the AI for analysis
Scanned PDFs
If a PDF contains no extractable text (it's a scanned image):
- The first page is rendered as an image
- The image is sent to the AI's vision capabilities
- 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).
