Free Syntax Tree Generator (mshang.ca) Alternative
The Syntax Tree Generator at mshang.ca is a simple, lightweight web tool for creating syntax trees from labelled bracket notation. Created by Miles Shang, it's free to use and doesn't require signup. You type bracket notation into a text box, click generate, and get a clean PNG or SVG tree diagram. It's fast and straightforward for users who already know bracket notation or have it from a textbook or course materials. If you prefer a visual interface where you build trees by dragging and connecting nodes, Fixie's Syntax Tree Builder offers a different approach.

Why Choose Fixie?
The Syntax Tree Generator (mshang.ca) is a no-frills tool that does one thing well: convert bracket notation to tree diagrams. If you already have bracket notation from a linguistics textbook, corpus, or assignment template, you can paste it in and get a tree instantly. The interface is minimal — a text box, a few options for font size and subscript notation, and a generate button. It's fast, reliable, and has been used by linguistics students for years.
The trade-off for simplicity is limited interactivity. You type bracket notation, click generate, see the result, and if you need to change something, you edit the text and regenerate. There's no live preview as you type, and customization options are basic. For users who don't already know bracket notation (e.g., [NP [Det a] [N tree]]), there's a learning curve — you need to understand how brackets nest and how to structure them correctly.
Fixie's Syntax Tree Builder removes the bracket notation step entirely. Instead of typing nested text, you drag nodes onto a canvas, connect them visually, and label them by clicking. The tree updates in real-time as you build, so you see exactly what you're creating without a generate step. This is especially helpful for beginners who are still learning how syntax trees work and find it easier to think visually rather than in nested text. Both tools are free and produce clean output. The choice depends on whether you prefer text-based input (faster if you know bracket notation) or visual building (easier if you don't).
