Grammar & Flow Check

By Product Management Skills by Pawel Huryn

Catch grammar mistakes, unclear logic, and awkward phrasing—get fix suggestions without rewrites.

Doc Co-Authoring Workflow

• Asks clarifying questions to gather all the context you have about the project or decision
• Helps you build each section by brainstorming options, then refining what you keep
• Tests your finished document with a fresh AI (no prior context) to find confusing parts
• Pulls in context from Slack, Google Drive, or other tools if you have them connected
• Creates a structured scaffold for your document type with all the right sections

Grammar & Flow Check

• Identifies grammar errors like typos, punctuation mistakes, and tense inconsistencies
• Flags logical problems such as unsupported claims, contradictions, or vague statements
• Spots flow issues including choppy transitions, passive voice overuse, and unclear pronouns
• Provides specific fix suggestions with location, rationale, and priority level
• Checks tone alignment with your objective (persuade investors, onboard users, etc.)
