SIL International

What SIL International does

SIL International is a Christian nonprofit organization founded in 1934 and headquartered in Dallas, Texas, that studies, documents, and assists in developing the world's lesser-known languages. Operating under the public-facing brand 'SIL Global' (previously the Summer Institute of Linguistics), the organization deploys 4,213 staff and volunteers across 119 countries to serve 1,572 language communities, with documented work on orthographies for over 1,300 languages since inception. SIL's core activities span language assessment, orthography development, literacy and multilingual education programs, dictionary creation, translation support, and language technology development. Primary beneficiaries are ethnolinguistic minority communities and deaf/sign language communities lacking access to Scripture, education, and health resources in their mother tongue.

SIL's product portfolio includes proprietary open-source software tools for field linguistics — FieldWorks Language Explorer (FLEx), WeSay, SayMore, Bloom, The Combine, LanguageForge, Lexique Pro, Pathway, SooSL, and DictionaryAppBuilder — alongside specialized fonts (Andika, SIL Fonts Collection) and reference platforms (Ethnologue, ScriptSource, Webonary). The organization contributes to Unicode character encoding standards and integrates with external tools such as Keyman keyboards and UBS Paratext. SIL also operates an extensive training infrastructure through partnerships with 20+ universities worldwide, ranging from certificate programs to master's degrees in linguistics, translation, and language development.

The revenue model combines donations and charitable contributions from individuals, churches, and organizations; fees from training and educational services delivered through university partnerships; and revenue from publications and resources via SIL Global Publishing Services. Services are provided free or at minimal cost to end-user language communities (a freemium pricing posture for non-commercial use), with no disclosed revenue figures available. SIL holds a Charity Navigator four-star rating, ECFA accreditation, and Candid Silver Seal, reflecting its governance and financial accountability standards as a faith-based nonprofit.

Scale indicators11 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Max Planck Institute for Psycholinguistics: MPI is a leading research institution studying language documentation, processing, and multilingualism, publishing comparable linguistic resources and overlapping with SIL on academic training and field methodology.

Direct peers

• Endangered Languages Project: Endangered Languages Project is a Google-supported collaboration between First Peoples' Cultural Council and the University of Hawaii that catalogs endangered languages worldwide, directly competing with Ethnologue for the language-data stewardship role.
• The Rosetta Project (Long Now Foundation): The Rosetta Project builds a digital archive of all documented languages, mirroring SIL's archival mission (Language & Culture Archives) and competing in the same space of long-term language data preservation.
• Global Recordings Network: GRN produces audio recordings of Scripture and language-learning materials in thousands of minority languages, sharing SIL's faith-based, Scripture-focused approach and overlapping heavily on target communities and donor base.
• Jesus Film Project: Jesus Film translates and distributes a Christian film in thousands of languages, sharing SIL's faith-based, Scripture-aligned mission and partially overlapping target communities and donor networks.
• Translators without Borders: TwB provides translation and language services for humanitarian and development contexts, sharing SIL's mission-driven, non-commercial approach to enabling marginalized language communities to access critical information in their own languages.
• Endangered Languages Archive (ELAR / SOAS): ELAR at SOAS University of London funds and archives documentation of endangered languages, closely overlapping with SIL's documentation, archiving, and training offerings for field linguists.
• Wycliffe Bible Translators: Wycliffe is the largest faith-based Bible translation organization and SIL's closest counterpart, partnering with SIL on translation projects and sharing donor networks, field staff, and training infrastructure for Scripture work in minority languages.

Others

• Linguistic Society of America: LSA is the principal professional society for linguists; SIL engages with it through academic conferences and shared researcher communities, serving adjacent ecosystem roles rather than competing directly for service delivery.

Broad incumbents

• Duolingo: Duolingo is a large commercial language-learning platform; though it serves a different (mass-market, major-language) audience, it represents the broader digital language-learning space in which SIL's literacy and English-with-Newcomers offerings sit.
