SIL has produced software that enables peoples of the world to use the computer in their mother language.

In order to have a complete index, the whole range of SIL software is covered here, from the state-of-the-art linguistic analysis program to ancient text processing tools that are only of historic interest. Searching for software by linguistic task, interface language, license or operating system can be done through LingTranSoft, which includes all SIL Software, plus other software used to support language development and translation tasks.

Please contact the Language Technology team if you have questions or need assistance.

A separate page lists fonts produced by SIL.















Web Applications

A Unicode Keyboard Layout Editor for Mac OS X versions 10.2 and later.

A way to author and archive linguistic papers or books using XML.


Unsupported Software

Unsupported software is available to use on an “as is” basis. The software may be helpful to accomplish tasks for which it was designed. However, due to limited resourcing, SIL will not provide support or bug fixes for the software.

Discontinued Software

Discontinued software has been deprecated. Because there are those who still rely on this software, or there exists data that was created using discontinued software, we retain the software in the event it must be used. We, however, strongly recommend migrating your data to one of our currently supported tools that supports the same task.
