English Grammar Visualization Tool
An open-source web-based tool for visualizing English grammar, distributed as a single HTML file. It supports AI-assisted sentence segmentation, color-coded annotation of grammatical constituents, a built-in local dictionary, and AI-powered word lookup, relying on the DeepSeek API for image recognition and grammar analysis.
Core Facts
Timeline (last 90 days)
Bilibili UP host "WaterBlood水" released an upgraded version of an open-source English grammar visualization web tool.
The tool is distributed as a single HTML file that can be downloaded for local use or accessed via an online link.
The tool requires a DeepSeek API key to be configured, which powers its text recognition and AI analysis features.
The tool supports two text input methods: pasting text and uploading photos.
The tool uses DeepSeek's API for image recognition and can intelligently extract only printed content while ignoring handwritten notes.
The tool uses different font colors to distinguish sentence components such as subject, predicate, object, predicative, attribute, adverbial, complement, appositive, and parenthetical.
The tool has a built-in local dictionary sourced from an open-source GitHub project, containing approximately 23,000 vocabulary entries.
The built-in dictionary can recognize common inflected forms of words (noun plurals, third-person singular verb forms, past tenses) and match them to their root forms.
Users can double-click a word to invoke AI-powered lookup, which can interpret it in context—for example, recognizing Trump as the proper noun for the person rather than a standard dictionary definition.
The tool's "Grammar Analysis" feature uses levels such as L0 and L1 to annotate the nesting relationships between main clauses and subordinate clauses, and identifies the subject, predicate, and object at each level.

Because the grammar analysis relies on AI, the results may still contain errors, and the author recommends treating them as a supplementary reference rather than a definitive answer.
