The Verdict
DeepSeek is built for developers and researchers, with a focus on chat and code-generation. Semrush targets digital marketers and agencies and leads with keyword-research and site-audit.
On pricing, DeepSeek is the clear winner for budget-conscious users — starting at $0.14/mo compared to $139.95/mo for Semrush. That $139.81/mo difference adds up quickly for growing teams.
DeepSeek has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Semrush requires a paid subscription from day one.
Feature-wise, DeepSeek offers broader built-in capabilities (8 features vs 6), while Semrush takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Semrush has a slight overall edge — but if free web chat with no subscription required matters most to you, DeepSeek may still be the right call.
