LyX — The Complete Guide: Writing Theses and Technical Reports With Equations, Free
LyX is a free document processor built on LaTeX, the typesetting system in which most papers and theses in science and engineering are written. The difference: in LyX you work in a graphical interface, see the structure and the equations on screen, and do not have to memorise commands.

- Equations — fast entry in LaTeX syntax (fractions, Greek letters) with instant display, and automatic numbering that stays up to date.
- Long documents — chapters, tables of contents, lists of figures and cross-references that do not break when you add a chapter.
- Typesetting — the result looks professional without manual formatting.
- Bibliography — linked to a .bib file, for example from Zotero.
- Templates — most universities and journals provide a LaTeX template that you can open in LyX.
Installation
On Windows, the LyX installer also downloads and configures a LaTeX distribution (MiKTeX). On macOS install MacTeX, and on Linux install TeX Live from the repositories. Then open Help → Tutorial, which teaches the basics in an hour.
Other languages
LyX supports right-to-left writing and mixing languages in the same sentence. Set the document language and produce the PDF with XeTeX or LuaTeX and a suitable font. Start from an existing template and check the settings once.
Alternatives
If you would rather write code directly and quickly, choose Typst, a modern typesetting system with simpler syntax than LaTeX. GNU TeXmacs has a full WYSIWYG editor and direct links to computer-algebra programs. For reports that mix code and results — Quarto.
