About Safegloss

Read the SafeGloss blog

SafeGloss is an open, research-capable glossary system designed to support multilingual learners while providing educators and researchers with a transparent, inspectable platform for studying vocabulary use in authentic learning contexts.

SafeGloss is intended to function both as a classroom tool and as a research instrument for examining how learners interact with vocabulary, definitions, translations, and language-support scaffolds during normal instructional use.

Safegloss.org is operated as a (pending) 501(c)(3) non-profit. Subscription fees are used to cover the cost of hosting, software maintenance, and administration.

Open-Source Core

SafeGloss Core is the maintained open-source application core, released under the MIT License.

It implements the central multilingual glossary, course, enrollment, and Exam Mode workflows. The hosted service includes additional private integrations, billing, analytics, deployment configuration, and legacy functionality not included in the public repository.

This licensing ensures that SafeGloss remains:

• Transparent and auditable
• Modifiable for research purposes
• Freely usable in educational contexts
• Resistant to enclosure as a closed or proprietary system

Why the MIT License?

The MIT License allows SafeGloss Core to be used, copied, modified, distributed, sublicensed, and sold, provided its copyright and permission notices are retained.

This permissive license supports:

• Inspection and independent auditing of the public core
• Adaptation for educational and research settings
• Self-hosted deployments under local control
• Reuse in compatible open-source and commercial projects

The software is provided without warranty. The public license does not imply that the repository is the exact source deployed at safegloss.com.

SafeGloss as a Research Instrument

SafeGloss may be used in two primary research configurations:

1. Hosted use via SafeGloss.org

   SafeGloss includes built-in analytics that allow researchers to study patterns such as:

   • Frequency and timing of glossary interactions
   • Types of terms accessed
   • Duration and repetition of engagement
   • Aggregate and group-level usage trends
   • Engagement patterns from optional quiz and gamification features when enabled

   This pathway supports observational and quasi-experimental research conducted in real classroom settings, using a shared, maintained platform.

2. Self-hosted deployment

   Researchers and institutions may install SafeGloss on their own infrastructure.

   Self-hosting enables:

   • Full control over data storage and retention
   • Alignment with institutional review board (IRB) or ethics requirements
   • Custom instrumentation, logging, or experimental conditions
   • Use in restricted, offline, or jurisdiction-specific environments

   In this configuration, SafeGloss functions as a locally deployed research tool, rather than a third-party service.

Data Ethics

SafeGloss is intended for responsible educational and research use across diverse instructional contexts, including classrooms that use quizzes and gamified learning workflows.

Institutions and researchers should define appropriate data handling practices for their setting, including retention, access controls, and governance procedures.

Institutions and researchers retain responsibility for consent, anonymization, and ethical use in accordance with their local regulations and review processes.

Source Code and Research Use

SafeGloss Core is the official open-source core of SafeGloss, the product offered at safegloss.com. It implements the central multilingual glossary, course, enrollment, and Exam Mode workflows. The hosted service includes additional private integrations, billing, analytics, deployment configuration, and legacy functionality not included in the public repository.

SafeGloss Core is available under the MIT License and may be forked, modified, and redeployed for research purposes.

GitHub repository: https://github.com/w9smz8qkh6-stack/safegloss-core

Researchers are encouraged to:

• Fork the repository for experimental or institutional use
• Modify instrumentation to suit specific study designs
• Document and publish methodological changes alongside findings

We welcome scholarly use, critique, and extension of the platform.

Research-Aligned Design Philosophy

SafeGloss is developed with the following principles:

• Transparency over optimization
• Reproducibility over proprietary advantage
• Teacher control over algorithmic opacity
• Respect for student data and classroom context

Use of LLMs

SafeGloss can use large language models (LLMs) to help generate glossary content. This is designed to reduce teacher workload while keeping outputs tied to a specific instructional setting.

When AI generation is enabled, SafeGloss uses two key inputs:

• Course and glossary context (e.g., course/program/authority metadata, subject, grade level, and optional teacher-provided context) to scope definitions and examples to the way terms are used in that learning environment.
• User language settings to determine which translation languages are needed and how audio pronunciations should be generated (including language-appropriate voices and pronunciation steering).

SafeGloss uses this information to generate:

• Definitions (scoped to course context, not generic dictionary meaning)
• Translations (term + definition + example sentence, into learner languages)
• Example sentences (simple, instructional, context-relevant usage)
• Audio pronunciations (text-to-speech using the selected provider/model)
