Example Syntax Trees
Draw a Syntax Tree Without Bracket Notation
No [S [NP ...]]. No qtree macros. No drag-and-drop.
Stop counting parentheses in [S [NP The] [VP [V left]]]. Type the sentence you're analyzing and the AI builds a labeled syntax tree with heads, phrasal categories, and X-bar projections. Works for English, Spanish, German, Japanese, Mandarin, and 40+ other languages.
Type or Paste Your Sentence
Write the sentence in plain text. Add a short note about the framework you want — Government & Binding, Minimalist bare phrase structure, or classic X-bar theory — and the AI follows that convention across the whole tree.
AI Parses the Sentence and Labels Every Node
The syntax tree generator assigns category labels (S, NP, VP, PP, CP, DP, TP), identifies heads and complements, and draws hierarchical structure. It marks wh-movement, NP-movement, and head movement with indexed traces where your framework requires them.
Export as PNG, SVG, or LaTeX qtree
Download the tree as a 4K PNG for homework and lecture slides, an editable SVG for Figma or Illustrator, or copy LaTeX qtree code directly into your syntax paper or thesis chapter.
One Syntax Tree Generator, Three Linguistics Workflows
Students · Researchers · Instructors
The same AI syntax tree generator handles intro syntax homework, publication-ready figures for journal papers, and full-semester teaching materials — without rewriting bracket notation every time.
Linguistics Students
Intro Syntax to Graduate Seminar
You understand how the sentence parses — you just need a clean tree diagram to turn in. Get a labeled syntax tree diagram for your homework, midterm review, or qualifying exam prep in under 30 seconds.
- Handles relative clauses, wh-movement, and subordinate CPs
- Renders in under 30 seconds — even at 1 AM before class
- Free credits on sign-up — no payment info needed
Linguistics Researchers
Publish faster, revise easier
Journal-ready figures for your syntax paper without fighting tikz-qtree or redrawing by hand after every reviewer comment. Export as LaTeX qtree, SVG, or PNG and drop straight into your manuscript.
- LaTeX qtree and tikz-qtree output for direct paste into papers
- Indexed traces for NP-, wh-, and head-movement
- Consistent formatting across every figure in your paper
Syntax Instructors
Undergraduate and graduate teaching
Build a full week of parse-tree problem sets, answer keys, and lecture slides in an afternoon. The syntax tree generator follows whichever framework your syllabus uses — Radford, Carnie, Adger, or Sportiche/Koopman/Stabler.
- Generate dozens of sentence tree diagrams for problem sets
- Consistent X-bar formatting across every worksheet
- Side-by-side trees for surface vs deep structure comparison

What Makes This Syntax Tree Diagram Generator Different
Not Another Bracket-Notation Parser
Most parse tree generators force you to write bracket notation like [S [NP [Det The] [N dog]] [VP [V barked]]]. This one reads the sentence directly and draws the tree — with X-bar theory, movement, and multilingual support built in.
Reads the Sentence, Not Brackets
Plain-Text Input Only
Paste a full English sentence and the AI identifies the head, complement, and adjunct of each phrase — then draws a labeled syntax tree matching how syntax textbooks actually analyze it. No preprocessing required.
Start free, upgrade as sentences get longer
Every account gets free credits on sign-up. Need more syntax trees for coursework, a dissertation, or a full semester of problem sets? Pick a plan that fits your workload.
How Linguists Actually Use It
Feedback from syntax students, linguistics researchers, and language instructors who stopped drawing parse trees by hand.
Dr. Emily Carter
Syntax Professor, UC BerkeleyI assign 40 parse trees a semester. Drawing the answer key used to take a full weekend. Now I paste each sentence in, check the output, and export as LaTeX for the handout.
Raj Khanna
Linguistics Major, University of MichiganMy intro syntax homework has ten sentences a week. I used to spend two hours drawing trees in Word. Now I get the tree, adjust if needed, and paste it straight into my PDF.
Dr. Hiroshi Tanaka
Postdoc, Sophia UniversityMost parse tree generators are English-only. This one handled my Japanese SOV structures correctly, including topic-marker ga/wa distinction. I used the SVGs in my workshop paper.
