The verdict

Relevance AI wins, 8.2 to 7.3

SmythOS has a free plan for building public agents; Relevance AI does not offer one to new signups. Relevance AI is cheaper to start once you do pay, $29 a month against SmythOS's $39 a month, and Relevance AI lets you bring your own model or key from Pro, while SmythOS includes that on every tier including its free plan. Relevance AI keeps 90 days of run history against SmythOS's 30, and hosts across four regions where SmythOS hosts only from the US.

Pick Relevance AI if you want lower cost, longer run history and more regions.

Pick SmythOS if you want bring-your-own-key on every plan including free.
