HashChat: the social network without language barriers

November 2, 2026 - Mingle Labs

HashChat started life as Mingle, a live voice translator. People used it in HelloTalk voice rooms, Discord calls, hostels, and meetups, and the same thing kept happening: once the language barrier was gone, they wanted to stay in touch with the person on the other side. A translator could not give them that.

So Mingle grew into HashChat (formerly Mingle): a social network where you post, follow, comment, and talk with people from other countries, and where every post, comment, chat, and voice conversation can be understood in your own language. Translation is no longer a tool you open. It is the floor everything stands on.

From translator to social network

Mingle answered one question well: "what is this person saying?" It translated continuous speech in real time, across three or more languages at once, even when the voice came from another app. That core is still inside HashChat. What changed is everything around it.

A feed of people from everywhere. Swipe through For You and Following, and see translations of posts written in Korean, Japanese, Spanish, or Vietnamese with one tap.
Comments that cross languages. Reply in your own language; everyone else can read it in theirs.
Profiles built for meeting the world. Each profile shows the languages someone speaks, the languages of the people they want to meet, and their level in each, so you know who is looking for someone like you.
Explore and follow. Search people and posts, follow the ones you like, and get notified when they post or reply.
Chats and voice talk with a live interpreter built in. One-to-one and group rooms where you just talk and HashChat interprets as you go.

Language exchange apps ask you to learn the language before the friendship can start. Global social apps assume you already share one. HashChat lets the friendship start first.

Comparison table

How HashChat compares with messengers and social apps.

LINE, WeChat, and WhatsApp are built for talking with people you already know. HelloTalk and Tandem are built for language exchange, Instagram for sharing, and Discord for communities. HashChat is the only one built around making friends across languages without a shared language. Features were checked against public store listings and product announcements in November 2026.

"Partial" means the feature exists in a narrower form, through add-ons, or behind a paid plan. HashChat voice talk is rolling out in November 2026. Apps update often; check the source links below for the current state.

Why a translator had to become a social network

Most people who want foreign friends are not looking for a lesson. They want to talk about food, football, a drama they just finished, or the hike they did last weekend. Language exchange apps make the language the topic. Global social apps quietly assume everyone speaks English. Either way, a lot of people never get past the first few messages.

HashChat removes that wall in every place a conversation can happen: the post you scroll past, the comment you leave, the chat you start, and the voice call that follows. You can post in your own language and still be understood in Seoul, Tokyo, Hanoi, or São Paulo.

Where HashChat is different

Voice talk that just works across languages. No other messenger or social app interprets voice conversations live. You speak naturally; HashChat handles the rest.
Profiles that say who you want to meet. Interest languages and levels make it obvious who is looking for someone like you.
Your existing voice apps, translated. Keep a HelloTalk voice room or a Discord call on speaker and HashChat interprets it live.
