Supported file formats
38 formats, three kinds
nymos names by content, so what matters is what it can read inside a file, not just the extension. Documents, text and data, and images are all handled, mixed freely in one batch. Video and audio are coming soon.
Documents

Read for their full text, tables and all. Scans fall back to OCR.

38 formats in all. A file with no readable content, an empty scan or a blank export, is left untouched rather than given an invented name.
How each group is read
The three groups reach the model in different shapes, and all of the preparation happens on your Mac before anything is sent.
- Documents: PDF, Word and PowerPoint are read for their full text, tables and slides included. Illustrator and RTF files come in the same way. A PDF that is really a scan, with no text layer, is read with on-device OCR instead.
- Text & data: plain and structured text is read directly, from a Markdown note to a JSON export to an .eml you saved from Mail. Subtitle files (.srt, .vtt) name from what is said in them.
- Images: a photo or screenshot is analysed for its content, and any text in the picture is read too. Where a photo carries capture details, the date taken and the camera feed the name.
Which providers can read them
Because nymos prepares every file on your Mac, extracting text, running OCR, and converting any image to a standard JPEG before it is sent, the provider never has to understand the original format. It receives text, or a plain JPEG.
That keeps the rules simple: every format works. Documents and text arrive as text, and images arrive as a plain JPEG the model reads directly.
Common issues
- "No text found": the file has no readable content. For a scan, OCR usually steps in; if even OCR finds nothing, the page is likely blank.
- Audio or video did nothing: those are not read yet. They are on the list, not in the app today.
