A multilingual messaging app for the people in your life
Espero is an AI-powered multilingual messaging app that automatically translates text, voice messages, images and video into each recipient's own language.
Write naturally, whether the person replying lives nearby or across an ocean.
What makes a messaging app multilingual?
A multilingual messaging app gives the reader a language choice, rather than making the whole conversation use one shared language. In Espero, every message is presented in that reader’s selected language, with the source wording still available.
Looking for the best multilingual messaging app for your situation? Start with the people you want to include: which languages they read, which devices they use, and whether they prefer typing or speaking. Espero has 100+ languages and one account across iOS, Android and the web.
Translation belongs inside the conversation
Reply to a particular message, add a reaction, pin an important detail or check read receipts. Photos, videos and voice notes belong in the same chat as your written messages.
Text translation costs nothing, including group messages. For the mechanics, see automatic message translation; for speech, read the voice note walkthrough.
Find the conversation that fits
Bring relatives into a family conversation, or keep everyday plans moving with a partner abroad. For work and communities, explore shared conversations and the translated group chat guide.
There are also guides for school communities, church members and language learners. A gathering with a speaker has a different workflow: AI live interpretation.
An illustrated plan for Saturday
Imagine a Finnish-speaking neighbour inviting a Spanish-speaking neighbour for coffee. As an illustration, “Nähdään lauantaina kahvilassa” reaches the Spanish reader as “Nos vemos el sábado en la cafetería”. The invitation and reply remain together, so both people can return to the plan.
