The short answer
Yes. Spanish is one of 12 languages a sub-account can choose for the HighLevel interface, and each user can override it in their own profile. Voice AI agents can be set to Spanish, or to Multilingual, which lets one agent switch between English and Spanish during a call. An AI Translate workflow action can turn text into Spanish before it is sent.
The HighLevel interface in Spanish
A sub-account sets its default under Settings, Business Profile, Platform Language, and each user can override that under My Profile. HighLevel lists Spanish alongside German, French for France and Canada, Portuguese for Portugal and Brazil, Italian, Dutch, Swedish, Danish, Finnish and Norwegian. Its coverage table marks areas including contacts, conversations, calendars, the page builder, email builder, payments, reputation and the client portal as translated. Notifications and notification emails follow each recipient's language setting, and any missing string falls back to US English. HighLevel says it used professional translators and AI for the work.
Voice AI agents that speak Spanish
Voice AI agents have a Language setting in Agent Details. Choose Spanish for a Spanish-only agent, or Multilingual so one agent can answer in English or Spanish and switch as the caller does; HighLevel pairs this with voice profiles tuned for both languages. For teams that review calls in English, the translation option converts the post-call transcript and summary into a target language, and it appears only when the agent language is not English. The same setting lists more than 50 other languages, from French and Portuguese to Hindi and Arabic.
Texts, emails and pages in Spanish
Messages you write in Spanish send like any others; what HighLevel adds is automation around them. The AI Translate workflow action takes text, such as a welcome message or an incoming reply, converts it from one language to another and passes the result to the next step, so a contact who picks Spanish on a form can get Spanish follow-ups. HighLevel prices translation as a premium AI workflow action at $0.01 per execution. Validation, error and success messages in funnels and websites follow the location's locale setting when one applies.
