What Conversation Exchange does well
Conversation Exchange has been around since 2005, which is a very long time for a language-learning site. That longevity is a real strength, and the site has several things going for it:
- Face-to-face exchanges. This is its signature. The home page leads with “meeting up with natives in your area,” and the search lets you look for partners by language and city. If you live in a big city and want a weekly coffee exchange, it is one of the most direct tools for that.
- Three kinds of exchange in one place. You can look for face-to-face partners, pen pals for longer written correspondence, or chat partners for text, voice and video.
- No lock-in. Once you find someone, you talk wherever you both like: its own ChitChat tool, Skype, WhatsApp, or a café.
- Free at its core. The membership page says the site is “completely FREE of charge,” with paid memberships that remove ads and messaging limits. Education accounts (emails ending in .edu) get the Unlimited membership at no cost, which is a nice touch.
- Simple and fast. There is no feed and no gamification, just profiles and messages.
- Learning resources. Tips, conversation topics, survival phrases and pronunciation pages sit alongside the partner search.
If you want an in-person tandem partner in your city, Conversation Exchange is still worth a try, and we would honestly suggest keeping your profile there even if you also use an app.
Where LangX differs
LangX is not a directory. It is an app where the conversation itself happens, with tools that make that conversation teach you something. Here is what that means compared to Conversation Exchange.
Matching runs in both directions
On LangX you only see people who speak the language you are learning and are learning a language you speak. Every match is a real exchange, so you spend less time messaging people who were never looking for your language. Conversation Exchange gives you a flexible search instead, which is powerful, but you do more of the filtering yourself.
Corrections are built in, and unlimited
The most useful thing a partner can do is fix your sentence. On LangX you hold any message and correct it right in the conversation. Corrections are unlimited on every plan, including Free. On Conversation Exchange, corrections depend on the chat tool you end up in.
Translation, voice messages and read-aloud in one place
LangX has translation inside the chat, voice and photo messages for pronunciation practice, and read-aloud so you can hear a message spoken. With Conversation Exchange you would put these together yourself from separate apps.
An app, not only a website
Conversation Exchange works well in a mobile browser, but it has no official app. LangX runs on iOS, Android and the web at app.langx.io.
Open source and no ads
LangX’s app and API are open source under BSD-3 on GitHub, and you can host your own instance. There are no ads on any plan. If you are looking specifically for an open source alternative to Conversation Exchange, this is the core difference.
Where LangX is weaker
Be clear-eyed about it:
- No live calls. LangX has voice messages, not voice or video calls. If you want live conversation, you can still meet a partner on LangX and move to a call elsewhere, just as you would with Conversation Exchange.
- Not built for in-person meetups. Conversation Exchange’s city search is better for that.
- A smaller community. Conversation Exchange has had two decades to grow. LangX is newer, so in some language pairs you will find fewer people.
- The free plan has limits. You can start 5 new conversations and use 20 translations per rolling 24 hours. Replies and corrections are never limited. See the plans page for details.
Who should pick which?
Pick Conversation Exchange if you want an in-person partner in your city, want a long-form pen pal, or already have a favorite calling app and just need to find people.
Pick LangX if you want an app where matching, chatting, corrections and translation all happen in one place, you care about open source and no ads, or you want a daily streak to keep you practicing.
Use both if you want the best of each: find a local coffee partner on Conversation Exchange and keep daily written and voice practice going on LangX. A guide on how to find a language exchange partner covers how to combine sources.

Getting more out of any language exchange
