Frequently Asked Questions: Grammarly vs Semflow
Grammarly has 58,867,412 monthly visits, while Semflow has 4,024. Traffic estimates describe audience size, not product quality.

Limitations
–Month-to-month billing on Grammarly Pro is steep at $30/member/month compared to the $12/member/month annual commitment ($144 billed upfront).
–Core writing intelligence and style rules remain primarily optimized for English dialects (US, UK, Canadian, Australian, Indian) rather than native multilingual grammar checking.
–Aggressive inline underlines and pop-up agent cards can feel visually intrusive in dense technical documents or code-heavy web editors unless muted per domain.

Chrome extension for any site
A Chrome extension brings full site audits, keyword research and optimization guidance to any website on any platform, not just Webflow and Framer.
Strengths & Pros
+Fixes happen right inside Webflow and Framer — no context switching
+Tracks AI answer-engine visibility alongside traditional rankings
+Unlimited sites and audits on every plan
+Chrome extension extends it to any platform
+Very affordable relative to full-suite SEO tools
+Does not inject code into your published site
Limitations
–Optimization still requires judgment — it guides fixes rather than doing all SEO for you
–Best value is for Webflow/Framer users; general-site users rely on the Chrome extension workflow
–Keyword research and reporting are strong but not as deep as some enterprise SEO suites
–Team seats and advanced reporting are gated to the Pro plan
