Grammar & Flow Check

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

What it is

This skill reviews your writing for grammar errors, logical gaps, and flow issues, then gives you targeted suggestions to fix each problem. Perfect for polishing PRDs, marketing copy, emails, or any important document before you hit send. The AI points out what's wrong and how to fix it—you stay in control of your voice.

What it does

  • 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.)

Use it when

  • You're finalizing a PRD, pitch deck, or important email and want a fresh set of eyes
  • You need to polish marketing copy or product messaging before launch
  • You're reviewing a draft and want to catch errors without losing your voice
  • You want to ensure your writing is clear, professional, and aligned with your goal
