About Writing Style Checker
A deterministic style checker for documentation, blog posts and product copy: paste a draft and it runs eight rules together, marking each finding with its line and column. It flags passive constructions, wordy phrases with a shorter replacement ("in order to" becomes "to"), filler words, hedges and clichés, weasel phrases such as "studies show" that claim authority without a source, sentences over 30 words, acronyms used without ever being spelled out, lists that mix Oxford comma styles, and double or spaced hyphens that should be dashes. A readability strip shows word count, Flesch reading ease and grade level for the same text. Because it uses fixed word lists and patterns rather than AI, the same text always gives the same findings and every flag explains itself; treat them as prompts for a human edit, not errors. It runs in your browser, and each rule is still its own REST endpoint, SDK function and MCP tool for docs pipelines and agents.
How to use Writing Style Checker
- 1.Paste a draft into the editor; findings appear sorted by position, each with its line and column, the rule that raised it and the exact words involved.
- 2.Turn off rules your style guide does not care about (for example the Oxford comma rule) with the toggles above the editor.
- 3.Click a line number to select that line in the editor, or group the results by rule to fix one habit at a time.
- 4.Watch the readability strip as you edit; most technical documentation reads best around grade 8 to 10.
