The original stays itself.
Pull out the PDF whenever you choose. Its bytes stay unchanged.
A native format experiment from Cyberdelic OS
A file, with room
for its context.
Keep an original PDF beside the reasons, questions and interpretations that travel with it.
Drop a .else or PDF.
On your deviceOpen a .else to read or edit it. Start with a PDF to create one. Nothing is uploaded.
Your files stay in this tab. Save a copy to keep your work.
What can I open?
Standalone two-readings .else files up to 64 MiB. Create from one PDF up to 12 MiB and 200 pages, with up to 65,536 characters of selectable text. Other .else profiles, encrypted PDFs and OCR are outside this first experiment.
One PDF / Two interpretations
Make room for context.
Your PDF stays unchanged. Only the source information and interpretations you enter here travel beside it. This draft stays in this tab until you save it.
The material and its interpretations remain distinct.
Save the PDF to open, print or send it through your usual apps.
Where it came from
Source information is declared. The file’s fingerprints check its bytes, not a person’s identity.PDF text (extracted)
AI-readable context

The file is a score
Carry the difference.
A PDF has its own life. Context gives it another. .else makes room for both, without asking an interpretation to become the original.
Two readings can coexist.
Keep each interpretation with its contributor. Human and AI words are labelled separately.
Keep a source in view.
Carry declared origins and byte fingerprints. Editing saves a new copy with a reference to the earlier file.
A small experiment between Carry’s use and Dear Elsewhere’s encounter. Read Field Note 45 for the artistic direction.
An ordinary desktop companion
Take the reader with you.
