Semrush Writing Assistant (SWA) is an SEO content optimization tool integrated into the Semrush platform. It analyzes your content in real time against your target keywords' top 10 Google results, providing scores across four dimensions: SEO, readability, tone of voice, and originality. For SEO, SWA recommends related keywords to include, identifies keyword stuffing, and suggests optimal article length.
The readability module scores content using the Flesch reading ease formula and flags overly complex sentences. The tone checker uses machine learning to evaluate if your content matches your intended tone (casual, formal, neutral). The originality checker scans against web content to identify potential plagiarism.
SWA works as a Google Docs add-on, a WordPress plugin, and directly in the Semrush content editor. It integrates with Semrush's broader SEO toolkit, pulling data from Keyword Magic Tool, Position Tracking, and Site Audit. As part of Semrush rather than a standalone product, SWA requires a Semrush subscription, which starts at $129.95/month — making it a premium option best suited for teams already using the Semrush ecosystem.
