JianTeX

Overview

The desktop app works offline, saves projects as ordinary local files, and requires no registration. The online version adds real-time collaboration, while organizations can self-host to keep collaboration content within their intranet. That range makes JianTeX unusually adaptable to different working arrangements, though it also means the desktop and online experiences serve distinct needs.

The project is described as MIT-licensed and free. JianTeX 0.1 alpha is the current release, and code signing and notarization are rolling out by platform—a meaningful caveat for people choosing software for essential work.

Key features

Source editing and PDF navigation

The desktop editor supports LaTeX and Typst with syntax highlighting, code completion, and live preview. SyncTeX links the source and PDF in both directions, so writers can move between a rendered passage and the code that produced it. Support for Tectonic, Typst, LuaLaTeX, XeLaTeX, and pdflatex gives users several engine options. The editor is source-based, not visual, so it is a better fit for people comfortable working with markup than for those seeking a graphical document editor.

Templates and project portability

More than 35 templates include NeurIPS, ICML, IEEE, Chinese theses, and résumés. This can reduce setup for common formats, though the range of templates does not remove the need to edit source. Existing Overleaf projects can be imported from a Git link or ZIP, and JianTeX can clone projects from Git URLs. Those routes make it easier to bring existing work into the editor rather than start over.

Collaboration and version history

The online version supports real-time collaboration using CRDT, with collaborators’ cursors and selections visible. Automatic snapshots can be restored from a timeline, and version history can sync with self-hosted Gitea or GitLab servers. GitHub and Google OAuth are supported for online sign-in. For teams with internal-network requirements, self-hosting keeps collaboration content from passing through third-party servers; solo writers who do not need shared editing may get more from the offline desktop app.

Pricing

Free and open source — 0.00 USD per free. The plan includes the desktop app, online version, and self-hosted option. It is a compelling starting point for individual writers and teams alike: the desktop route avoids a registration requirement, while collaboration and self-hosting are also included. No seat or project caps are given for the plan.

The free offering is not a substitute for release maturity. The software is at 0.1 alpha, so readers who depend on a settled toolchain should consider that trade-off before moving essential work.

Platforms

JianTeX is available for macOS, Windows, Linux, and the web. Desktop apps support offline work; self-hosting provides an option for organizations that want collaboration data kept inside their internal network.

Who it's for

JianTeX is a strong fit for LaTeX or Typst writers who value local files, offline editing, multiple typesetting engines, and the ability to collaborate online or self-host. It is less suited to people who want visual editing or need an established release for critical work.

Pros and cons

• Pro: Offline desktop editing with ordinary local files and no registration requirement suits independent work and low-connectivity settings.
• Pro: LaTeX and Typst support, several engines, SyncTeX navigation, and 35+ templates cover a broad academic writing workflow.
• Pro: Online collaboration, version snapshots, Git import and cloning, and self-hosted deployment give teams several ways to manage shared work.
• Con: The 0.1 alpha release makes it a less reassuring choice for users who need mature software.
• Con: There is no visual editor, so writers must be comfortable with source-based authoring.

Alternatives

LaTeX Editors is a useful place to compare the category. Choose VerbTeX if you want a freemium option spanning Android and iOS as well as desktop and web; its free plan caps local and cloud projects, documents, and uploads at two each. Oleafly is another free desktop choice for Linux, macOS, and Windows, with no subscription for the desktop app, though paid AI providers may charge for usage. Texpile suits readers looking specifically for a free offline desktop editor on Linux, macOS, or Windows.

TeXstudio is worth considering for a free, GPL v2 open-source editor on Windows, Linux, and macOS. MiKTeX is another free option across those desktop platforms. TeXlyre covers Linux, macOS, Windows, and web at no cost. For browser-based work with unlimited projects, collaborators, and full version history, consider TeXposit; its free plan also includes an AI assistant and no compile timeouts. Overleaf is a freemium web alternative: its free plan allows unlimited projects but one collaborator per project, while its Student plan allows ten collaborators per project.

Verdict

Choose JianTeX if you want a free LaTeX and Typst workflow that can move from offline desktop writing to online collaboration or intranet self-hosting. Its mix of source tools, PDF navigation, templates, and Git support is persuasive for academic writers, but its 0.1 alpha release is the main reason to look elsewhere if reliability matters more than flexibility.
