LetX and TeXstudio compared by hosting, setup, collaboration, compilation, AI features, MCP support, and offline use.
Short answer
LetX provides a hosted browser workspace, real-time editing, cloud compilation, templates, Lexi, and MCP. TeXstudio provides an open-source desktop editor, offline use, extensive customization, and control of the local LaTeX toolchain.
Feature comparison
| Area | LetX | TeXstudio |
|---|---|---|
| Product model | Hosted browser application | Free, open-source desktop application |
| Setup | No LaTeX installation; compilation runs in the cloud | Requires TeX Live, MiKTeX, or another local distribution |
| Collaboration | Native project sharing, cursor presence, and real-time CRDT editing | Primarily local; recent releases include Teamtype-related collaboration work rather than a hosted project service |
| Compilation | Managed pdfLaTeX, XeLaTeX, and LuaLaTeX environment | Local and highly customizable build system with multiple compiler tools |
| AI | Lexi operates on the project and compile log | Editing assistants focus on LaTeX authoring; no equivalent hosted project agent is documented |
| MCP | Hosted OAuth 2.1 server | No official project MCP server documented |
| Offline use | Requires a connection for the hosted editor | Strong offline workflow after local installation |
| Editor depth | Focused collaborative web editor | Advanced syntax highlighting, reference checking, integrated PDF viewer, macros, and customizable commands |
Prices, limits, and features change. This is a dated research note, not a substitute for checking each vendor’s live plan page.
