If you need to message someone who speaks another language — a partner, family abroad, a global team, a friend you met travelling — you have a few options: your phone's built-in translation, a standalone translator app, or a messenger built around translation. Here is how they differ, and where Espero fits.
Espero is a multilingual cloud messenger where everyone writes in their own language and AI translates messages for each reader. It works in one-to-one chats and groups, and members can choose from a catalog of 100+ languages. You write naturally, each person reads in theirs, and the original remains available. It runs on iOS, Android and the web with one account. Transport and provider-managed storage are encrypted, but ordinary cloud chats are not end-to-end encrypted.
| Espero | Translation built into another messenger | Standalone translator apps | |
|---|---|---|---|
| Everyone writes their own language, both ways, automatically | Yes — core | Varies by provider | Usually copy-paste |
| True multilingual group chat (many languages at once) | Yes — reader-specific | Varies by provider | Not a group chat |
| One account on iOS, Android and web | Yes | Varies by provider | Varies |
| Voice notes, images & video subtitles translated | Yes | Varies by provider | Varies by tool |
| A real messenger (reactions, replies, pins, read receipts, media) | Yes | Yes | No |
| Free to start | Yes | Varies | Varies |
| Encrypted in transit & at rest · honest about not being end-to-end | Yes | Varies | Varies |
Categories necessarily generalise across products that change often. Check each provider's current documentation for supported devices, regions, languages, prices and privacy terms. Espero's row reflects its public product as of the date above.
Some general-purpose messengers include translation, but the exact workflow and availability depend on provider, device, app version, region and plan. That may be the simplest choice when everyone already uses the same compatible service. Espero instead makes reader-specific translation the core conversation model and uses one account across iOS, Android and web.
A translator app turns one phrase into another, but you copy out of your chat, paste in, translate, and copy back. Espero removes that loop entirely — translation lives inside a full messenger with reactions, replies, pins, read receipts, media and themes, so you simply chat.
Several apps put translation inside chat. Espero's current combination is reader-specific translation for text, voice notes, images and video subtitles across iOS, Android and web, together with explicit disclosure that ordinary cloud chats are not end-to-end encrypted. Secret Chat is not currently available.
The best fit depends on platforms, privacy, languages and media. Espero is built for ongoing one-to-one and group conversations where each person writes in their own language and reads a reader-specific translation, across iOS, Android and web.
Yes — Espero translates messages automatically for each reader and keeps the original available. Voice notes, images, uploaded videos and YouTube links also have translation features.
Yes. In an Espero group, members write in their own languages and each person reads in their selected language. The catalog supports 100+ languages, with quality and feature availability varying by language.
Translation is Espero's core conversation model, not a per-message add-on. Built-in translation can be simpler when everyone already uses the same compatible service; its availability varies by provider, device, region, version and plan.
Server-side translation requires processing message content. Espero encrypts ordinary cloud chats in transit and at rest, but they are not end-to-end encrypted. Espero does not sell message content, use it for advertising or train its own models on it. Secret Chat is not currently available.
