How it works
Academic drafts frequently suffer from two grammatical structural errors: comma splices (joining two independent clauses with only a comma, such as “The sample was small, however the effect was significant”) and fused run-ons (joining clauses without punctuation or coordinating conjunctions).
The tool scans sentence boundaries for conjunctive adverbs preceded by commas instead of semicolons, pronoun-verb clause starts following uncoordinated commas, and sentences exceeding 35 words with high clause density.
For each issue detected, the tool explains the structural cause and recommends punctuation repairs: inserting a semicolon, adding a coordinating conjunction, or splitting the thought into two distinct sentences.
All structural parsing runs locally in your browser.
Why it matters for academic writing
Run-on sentences and comma splices force readers to re-read complex academic arguments multiple times. Clean sentence boundaries ensure reviewers grasp your findings on the first read.
