MyMemory: next generation Translation Memory technology

What is MyMemory?

MyMemory is the world's largest Translation Memory. MyMemory is 100% free.

It has been created collecting TMs from the European Union, United Nations and aligning the best domain specific multilingual websites.

You can download memories for free in TMX format and use them with your CAT tool of choice. You can also contribute to make MyMemory even better with your memories, or editing entries. When no human translation is found for your sentences, MyMemory will help you with state-of-the-art Statistical Machine Translation technology.

Getting Started - Download your first TM! It's all free!

  1. Go to and click on Log in (username: demo - password: demo).
  2. Click on Download a TMX.
  3. Upload a small .txt file you want to translate, choose source and target languages.
  4. Click on Create memory then wait a few minutes while your memory is created.
  5. Download your TMX file and import it in your CAT tool, making sure that the languages match.
  6. Translate your document with your CAT tool.

Note. This is the easiest way to download a memory, but it does not guarantee the best results. Please have a look at the detailed instructions for creating a Translation memory from an empty TMX file.

Look up terms and segments from MyMemory's web interface.

MyMemory works like a linguistic search engine which you can use to look up translated segments and terminology in any language pair and subject domain.

Create a custom Translation Memory for the document you are translating.

MyMemory lets you generate a TM using your own Translation Memories and TMs from other translators, world-class companies and from the web.

Contribute your TMs to create more accurate memories containing matches from your assets.

You can further improve the TMs you export from MyMemory by contributing your own translation memories.

Anything else?

MyMemory's goal is to help translators work faster and better by rendering existing translations universally searchable and accessible. The next big thing is going to be seamless integration with CAT tools, which will see MyMemory move right onto your desktop as a virtual local memory.
