Core concepts

The handful of ideas that explain how PrismaTex works.

Project

A project holds all the files of a document: .tex sources, .bib bibliography, images, .sty and .cls styles. It is saved online, so you can open it from any computer once signed in. Only you and the people you invite can access it.

Main document

The .tex file that is compiled to produce the PDF — the one with \documentclass. Other .tex files are included from it with \input or \include. You choose the main document in the Compile button's menu, under Main document.

Compilation

PrismaTex compiles your sources on its servers with a full TeX Live distribution, in an isolated environment, and shows the resulting PDF to the right of the editor. The default engine is pdfLaTeX; XeLaTeX, LuaLaTeX and Latexmk are also available. See Compiling and fixing errors.

Autosave

Your changes are saved automatically shortly after you type. Ctrl + S (⌘ + S on Mac) saves right away and recompiles.

The assistant's two modes

• Ask (read-only): the assistant answers questions about the project. It doesn't change any file.
• Edit (propose changes): the assistant prepares changes to your files, compiles and checks them, then hands them to you.

See Using the assistant.

Proposal

The changes prepared by the AI form a proposal. Nothing is final until you keep it, and the project is backed up automatically just before. See Reviewing AI changes.

Versions

A version is a snapshot of the project at a given moment. PrismaTex creates some automatically (when compiling, before each AI edit, before each restore) and you can save your own, with a note. See Version history.

Template vs. AI model

Two different things you will meet in PrismaTex:

• a template is the starting layout of a project, such as an ACL paper or a thesis;
• an AI model is the engine behind the assistant (Luna, Sol or Terra).

AI credits

AI features use credits, counted in euros, according to the amount of text processed and the AI model used. Editing, compiling and collaborating are free and unlimited. See Plans and AI credits.
