Type on the typeset page as in Word, get the PDF from real TeX
Live, keep a clean .tex that Overleaf, Git and any TeX open. Try it now at
https://rikuy.rackebrandt.pe/: no install, no account. If it helps you, a star here is how
other people find it.
Rikuy is Quechua for "to see". It is a LaTeX editor in the browser where you type on the
typeset page. Click into a paragraph, a formula, a table cell or a footnote on the rendered page
and edit it there: Rikuy patches the .tex source in the smallest way that makes the change,
and undo gives the source back byte for byte. Real TeX Live 2026 (pdfTeX, XeTeX and LuaHBTeX,
compiled to WebAssembly) runs in a Web Worker and makes the PDF. Nothing is installed and there
is no account; documents stay in the browser until you send them, as a share link that carries
the document itself, a file, or a git push.
Open it at https://rikuy.rackebrandt.pe/ (also reached as https://rackebrandt.pe/rikuy/): the
page installs as an app, works offline after one visit and reads and writes Word files. To build
the editor on your own machine you need node 22 and Python 3: npm ci && npm run build && npm run serve, then open http://127.0.0.1:8790. The PDF
pane also needs the TeX tree, which takes the longer build under Running it.
