Pros & Cons
Beehiiv
+ AI Writing Assistant built-in — draft, refine, and rewrite newsletter content
+ Best free tier in the category (2,500 subscribers, no watermark)
+ Boosts network — get discovered by other Beehiiv readers automatically
+ Advanced analytics: scroll depth, click maps, subscriber growth attribution
+ Native monetization: ad network + paid subscriptions + referral programs
− Limited design customization vs. platforms like Substack or Ghost
− AI features are helpful but not as deep as standalone writing tools
− Scale plan needed for premium features like boosts and A/B testing
Grammarly
+ Works everywhere: Gmail, Docs, Notion, Slack, browser
+ Tone detection tells you how your writing sounds to others
+ Plagiarism checker covers 16B+ web pages
+ Generative AI rewrites weak sentences with one click
+ 30M+ daily active users — team adoption is frictionless
− Not a content creation tool — it corrects, not writes
− Free tier lacks advanced suggestions and plagiarism
− Expensive at $30/mo for what is ultimately a grammar tool
