Groups in any mix of languages
Up to 20 people per group. Five languages in one chat, and nobody is left out.
A messenger with translation built in
Write in your language. Everyone reads it in theirs.
Olingo Chat translates every message for each person in the chat. Your friend in Seoul reads Korean, your teammate in Madrid reads Spanish, and you just type the way you talk.

How it works
Talk like you share a language
-
Pick your language
Choose one of 40 languages when you sign up. You can change it any time in Settings.
-
Write the way you talk
Slang, names and emoji included. Nothing to copy into a translator, no switching apps.
-
Everyone reads their own
A moment later each person sees your message in their language. Tap Show original for the exact words.
Translation
Translation that reads like a person wrote it
Olingo Chat doesn't translate word by word. It reads the conversation so replies make sense, and it keeps the tone friendly.
-
Understands context
It reads the last few messages, so short replies like "me too" and the subjects Korean and Japanese often leave out come through correctly.
-
Polite by default
Korean translations use the friendly polite style (해요체), so nobody sounds rude by accident.
-
Leaves the right things alone
Names, emoji, links and numbers stay as they are. "ok", "lol" and "haha" don't need a translator.
-
Never leaves you waiting
The original arrives instantly. If a translation is ever unavailable, you still have the message and a Retry button.

Security
Encrypted on the way. Encrypted at rest.
Every message, translation, photo and file is encrypted while it travels and before it's stored. Here's what happens to a message after you press send.
-
Sent over HTTPS
Your message leaves your phone or browser over an encrypted connection, so nobody else on your Wi-Fi or network can read it.
-
Translated in-house
Olingo Chat's own server translates it, on the same machine. It's never sent to an outside translation service or AI company.
-
Encrypted before it's saved
The message, each translation and any photo or file are encrypted with AES-256 before they're stored.
-
Delivered over HTTPS
Everyone in the chat receives it in their own language, over an encrypted connection again.
The key is kept apart
The encryption key is stored separately from your messages. A copy of the database or a backup shows only scrambled text.
Tampering is detected
Each message is sealed to the exact place it's stored. If saved data is altered, swapped or cut short, Olingo Chat notices.
Every access is logged
Olingo Chat's admin tools list chats without their content. Opening one, for example to look into an abuse report, needs a written reason, recorded before anything is shown.
Sign-in that's hard to steal
Passwords are hashed with Argon2, never stored as typed. Sign-in tokens are kept only as hashes, so even a leaked database can't sign anyone in.
Locked down on your phone
Your sign-in is kept in the phone's secure storage, and Olingo Chat can ask for your fingerprint or face before it opens.
You decide who reaches you
Let everyone message you, only people in your groups, or nobody new. Block anyone, and sign out any device you don't recognise.
Encrypted
- Message text
- Every translation
- Photos and files
- File names
Not encrypted
The server needs these to deliver messages:
- Usernames, display names and email addresses
- Profile pictures
- Group names and who is in each chat
- When each message was sent
Is Olingo Chat end-to-end encrypted?
No. To translate a message, the server has to read it, and end-to-end encryption would prevent that. Instead, messages are encrypted on the way and in storage, and the server decrypts them to translate and deliver them, on Olingo Chat's own hardware.
Technical details
- Stored text (messages, translations and file names): AES-256-GCM with a fresh random 96-bit nonce for every value, bound to where it's stored so it can't be moved to another message unnoticed.
- Files: encrypted while they upload, in 64 KiB pieces sealed with AES-256-GCM under a key made for that one file (HKDF-SHA256). The last piece is marked, so a shortened or reordered file is rejected.
- Connections: HTTPS (TLS) for the web app, the API and the live WebSocket connection.
- Passwords: Argon2id. Sign-in tokens: 256-bit random values, stored only as SHA-256 hashes and replaced every time they're refreshed. Changing your password signs out your other devices.
- Sessions: in the browser, HttpOnly, Secure, SameSite=Strict cookies that page scripts can't read; on phones, the system's secure storage.
- QR sign-in: a code alone never signs anyone in. A device that's already signed in has to approve the new one, and each code expires after 2 minutes and works once.

Questions people ask
Do I need an invite?
Yes, for now. Olingo Chat is invite-only while it grows. Enter the code you received when you create your account.
How good is the translation?
Olingo Chat uses a modern AI model that understands context, slang and tone, and keeps names, emoji and links as they are. No translation is perfect, so the exact original is always one tap away.
Are my messages encrypted?
Yes. Messages, translations, photos and files travel over encrypted HTTPS connections, and they're encrypted with AES-256 before they're stored. The key is kept apart from the database, so a copy of it or a backup shows only scrambled text.
Is Olingo Chat end-to-end encrypted?
No. Translation needs the server to read a message, which end-to-end encryption would prevent. Olingo Chat translates on its own server, never with an outside service, and opening a chat as an admin takes a written reason that is logged first.
Can other people see what I originally wrote?
Yes. Anyone in the chat can tap Show original to see your exact words, just as you can with theirs.
What happens if I change my language?
Go to Settings, then Profile, and pick a new language. New messages arrive in it right away, and older messages are translated when you scroll back to them.
Which devices does Olingo Chat work on?
Any computer with a modern web browser, and Android phones. An iPhone app is coming. Your chats are the same on every device, and you can sign in on a computer by scanning a QR code with your phone.
How do I install the Android app?
Download the APK on your phone and open it. When Android asks, allow your browser to install apps, then tap Install. New versions install over the old one, and your chats stay where they are.
What happens to my messages if I delete my account?
Deleting your account permanently removes it, along with the messages and files you sent. Groups that are left with no members are removed too.
Say it your way. They'll read it theirs.
