Naturable – AI Writing Pattern Checker

Underlines AI writing patterns (AI words, template openers, em dashes) where you type. Runs locally; nothing is uploaded.

Naturable underlines the patterns that make writing sound like a chatbot, in the text boxes of the sites you choose, and explains each one. What it flags • Overused AI vocabulary, such as "delve" and "leverage" • Template openers and closers, such as "The future looks bright" • Vague sources, such as "Experts believe" • Leftover assistant phrases, such as "I hope this helps!" • Stacked hedges, wordy filler and heavy em dash use How it works • Turn it on for a site from the toolbar button. Chrome asks once, for that site only • Hover an underline to see the rule, why it reads as AI-written, and what to do instead • Ignore a phrase you meant to use, or open the full explanation on naturable.app • Right-click selected text and choose "Check with Naturable" to see a score and every finding in the side panel • Paste any text into the side panel, including from editors that can't be underlined • Choose what you're writing (email, blog, academic and more) to adjust how strict it is Private by design • Runs on your device. Your text is never uploaded, and there's no account • It stays off until you turn it on for a site, and never turns on for banking, payment or sign-in pages • It doesn't read password, payment or one-time-code fields Open rules Every rule is open source, with examples and tests, and is the same one the naturable.app editor uses. English rules are stable; Chinese rules are in beta. Naturable is not an AI detector. A flag is a style signal, not evidence of who wrote the text. It doesn't rewrite your text; you decide what to change.
