Phext is a re-invention of plain text for the ASI era. I dredged ASCII control codes to steal 9 more delimiters, giving you access to a universal text format. Phext supports utf8 and binary in the same file, and requires no escaping for plain text. Binary rides in the same file as base64 scrolls: no side files, no escaping, no special tooling. Compress the file with xz when you want it small; open it in any text editor when you want it readable. Worst case, it's still just text!
Phext is endlessly composable - you can stuff literally any text file format into a .phext (verbatim), and it just ... works.
Phext is plain text in 11 dimensions: a file of scrolls, each at a coordinate - and still plain text. Phext Edit is its web editor. Navigate by coordinate, browse the dimension tree, search, edit any scroll and save to the server. Live demo, no sign-in; sign in with Google, GitHub, or X for your own files. Free no-login utilities: Up Goer Five, Singular, coordinate TTS, Phext Previewer, and Learn You Phext - a phext tutorial that is itself a phext. Open source (phext-lattice). No ads, ever.
