Byte-exact, and fast.

We don't ask you to trust the instant preview. We compare its PDF, byte for byte, with the engines you already use, and we publish how fast it is on real documents.

Byte-exact

The same bytes, every time.

Each document is built by PhiTeX and by the reference engine; the outputs are normalized only for the fields TeX itself varies (creation date, document ID) and then compared with cmp.

Performance

        
Instant stays instant as documents grow.

        
A full rebuild grows with the document. PhiTeX's edit grows with the change.

How we measure.

      

      

        
Corpora
TeX Live's own documentation, the TRIP test, and a sample of arXiv sources, frozen by hash. The list is published with the results.

        
Machines
Named hardware, a quiet machine, the median of 11 runs after 3 warm-ups. Browser figures in Chromium, on the same wasm the extensions ship.

        
Keystroke → page
From the editor's transaction to the repainted page on screen, measured in the page, not in the core alone.

        
Reproducible
One command runs it all in a sandbox; the scripts and raw numbers are in the repository.
