Tone

Tone and form of address

The widget's built-in labels speak to the visitor as tú: "Escribe un mensaje...", "Envíame este chat por correo". That is the norm for chat in most of Spain and Latin America and for retail, travel and software brands.

Banks, insurers, clinics and law firms often prefer usted. The labels stay in tú, but everything the bot says is yours to set: write the greeting with usted and give the AI agent one line in its instructions.

An instruction you can give the AI agent:

Trata siempre al cliente de usted, con un tono cordial y profesional. Usa español neutro y evita expresiones propias de un solo país.
  • Mixing the two in one conversation reads as careless: if the greeting says usted and a later answer says tú, add the instruction above.
  • Neutral Latin American Spanish (español neutro) is the safest default for a bot that serves several countries.
  • Keep exclamation and question marks paired (¡...! and ¿...?) in your own messages; the AI does this on its own.
Regions

Regional differences in Spanish

  • Spain: vosotros for the plural you, ordenador and móvil, prices with a decimal comma.
  • Mexico and Central America: ustedes for the plural, computadora and celular, prices with a decimal point.
  • Argentina, Uruguay and Paraguay: everyday speech uses vos ("¿vos querés...?"); most brands still write in tú or neutral Spanish online.
  • United States: visitors often switch between English and Spanish in one conversation. The AI answers in the language of each message, so a reply can change language mid-chat.

Write dates and prices in your knowledge base the way your customers expect them. Words such as hola, gracias, precio, horario, cuánto, cuesta tell the AI a message is in Spanish; for a one-word first message it uses the visitor's browser language as a hint.

Why it matters

Who you reach in Spanish

Spanish has about 635 million speakers, about 520 million of them native, according to the Instituto Cervantes 2025 yearbook El español en el mundo. More than 80% of native speakers live in the Americas, which is why a Spanish bot usually needs to sound right in Mexico and Colombia as well as in Spain.

Troubleshooting

Fixes for Spanish bots

What you seeThe fix
A customer in Spain finds the bot too casualAdd the usted instruction above and rewrite the greeting with usted. The built-in labels stay in tú.
Answers use vocabulary from the wrong countryWrite the knowledge base in the variety most of your customers use, or tell the agent to use neutral Spanish.
The bot switched to English mid-chatThe visitor wrote that message in English (common in the US). The next Spanish message brings the reply back to Spanish.
FAQ

Spanish chatbot: common questions

Does the widget use tú or usted?

The widget's built-in labels use tú. Your own greeting and the AI's replies follow what you write and instruct, so a bank or law firm can use usted.

Will it understand Latin American Spanish?

Yes. The AI reads Spanish from any region and replies in Spanish. Write your knowledge base in the variety your customers use so product terms match theirs.

Can it handle visitors who mix English and Spanish?

Yes. Each reply follows the language of the visitor's latest message, so a conversation can move between the two.

Does my knowledge base need to be in Spanish?

No. The agent answers in Spanish from English content too. Spanish content gives the most natural wording for local terms, sizes and delivery details.
