Replika vs Synthesia

Which should you choose?

These tools serve entirely different markets and shouldn't be compared directly. Replika is a personal AI companion for emotional support and friendship simulation; Synthesia is an enterprise video production platform. Pick Replika if you need a judgment-free conversational partner for daily emotional support or to combat loneliness—though understand it's not a clinical substitute. Pick Synthesia if your organization needs to produce training, marketing, or internal videos at scale across multiple languages without hiring actors or videographers. Synthesia excels at business efficiency; Replika excels at personal connection. The only overlap is that both are freemium tools, but their value propositions are completely distinct.
