ProphetAI Proofreading Tool for Chrome
Proofread and polish any text on the web with Prophet. Fix grammar, improve clarity, and ensure professional quality directly in your browser.
Why proofreading slows you down today
Catching your own grammar mistakes, typos, and awkward phrasing is difficult because your brain auto-corrects familiar text.
Basic spell checkers miss contextual errors, homophones, and stylistic issues that make writing look unprofessional.
Proofreading emails, social media posts, and web content across different platforms requires checking each one individually.
Ensuring consistency in style, terminology, and formatting across a long document requires multiple focused passes.
How Prophet changes proofreading
Identifies and corrects grammar, spelling, punctuation, and style errors with explanations for each suggested change.
Detects issues that basic spell checkers miss, including contextual errors, wordiness, passive voice overuse, and unclear references.
Checks text directly on any webpage, including email composers, CMS editors, social media post boxes, and form fields.
Maintains your original voice and intent while improving technical accuracy and readability.
What Prophet actually does for proofreading
Prophet is not a chat box that reads pasted text. It works against the live page through Chrome, using the same browser tools every time. Here is the sequence for proofreading, and the tools it calls at each stage.
1. Reads what is in the editor
Prophet checks the live contents of the text field rather than a copy, so it catches what you have actually written.
take_snapshotget_page_content2. Applies fixes in place
Accepted corrections are written back into the same field by element ID.
fill_element_by_uid3. Checks long documents section by section
It scrolls through the document and reports issues with enough surrounding text that you can find them.
scroll_pagesearch_snapshotPrompts to try for proofreading
Open the Prophet side panel on a page where you would normally do proofreading by hand, then paste one of these in.
“Proofread this text and list every grammar, spelling, and punctuation error you find.”
“Rewrite this paragraph to fix all errors while keeping my original tone and meaning.”
“Is this email professional enough to send to a client? Suggest any improvements.”
“Check this blog post for consistency in tense, voice, and formatting.”
“Simplify this text to an 8th-grade reading level while preserving all the important information.”
