The Verdict
Grammarly is built for writers and students, with a focus on grammar and spelling. Intercom targets saas companies and startups and leads with messenger and ai-bot.
On pricing, Grammarly is the clear winner for budget-conscious users — starting at $12/mo compared to $39/mo for Intercom. That $27/mo difference adds up quickly for growing teams.
Grammarly has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Intercom requires a paid subscription from day one.
