Introduction

NO.B612 LaTeX Editor is a LaTeX editor application available on the Apple App Store and Microsoft Store. Features include: outline/file tree, editor, PDF preview, log viewer, two-way sync search, and more. You can use it as:

An out-of-the-box LaTeX editor, a remote LaTeX compiler

No complex environment setup or configuration — focus on what interests you most.

Quick Start

After installing from the Windows Store or Mac App Store, you can start right away.

1. Open the app and click the "Create Project" button
2. Name the project: "test"
3. Click "Choose Directory" and select a folder, e.g. your Documents folder
4. Click "Create Project" — this creates a folder named "test" in the chosen directory and opens the editor for you to write LaTeX.
5. Write something, save (Ctrl+S on Windows, Command+S on Mac), and it will automatically compile in the cloud and display the latest PDF.

"Create Project" is great for creating a simple LaTeX project to learn and test syntax. In practice, you often already have a LaTeX project folder — use "Open Project" for that.

Open Project

You can open a project just created via "Create Project", an existing project on your computer, or a template downloaded from the web. Steps:

1. Open the app and click "Open Project" — this opens your file browser
2. Select the LaTeX project directory and click "OK"
3. If the project has multiple .tex files, you need to designate one as the main .tex file
If you select the wrong directory in step 2, cloud compilation will fail. Reopen the project and select the correct directory.
If you select the wrong main .tex file in step 3, cloud compilation will fail. Open the left file tree and set the correct .tex file as main.

Forward Search

Double-click text inside a document environment in the editor, and the PDF preview on the right will automatically jump to the corresponding area.

If it stops working, the project on the remote server may have expired and been deleted, so the synctex file is missing. Recompile the LaTeX project to fix it.

Inverse Search

Click content in the PDF, and the editor will automatically jump to the corresponding source line.

If it stops working, the project on the remote server may have expired and been deleted, so the synctex file is missing. Recompile the LaTeX project to fix it.

Clean & Compile

This triggers a full re-upload of your LaTeX project and performs a fresh compilation from scratch.

Adjust Layout

Drag the dividers between the left sidebar, editor, and PDF preview to resize panels.
