Teachers never needed help knowing what a great assessment looks like. They needed the hours back to build one. Teachers set the blueprint. Relay builds the assessment.

Assessments shaped by learning objectives.

Relay uses learning objectives, reading level, difficulty, and curriculum standards to guide question generation. Multiple-choice answers help reveal what students understand and where they need more support.

Less preparation, with teachers in control.

Creating assessments takes time throughout the school year. Relay generates a draft from the teacher’s course materials, leaving teachers in control of what gets taught and tested.

How it works

Teachers upload their course materials and choose the learning objectives, reading level, and question types. Relay generates an assessment they can edit and share through their existing tools.

Questions grounded in the course materials.Relay uses the teacher’s slides, readings, and units to create questions that reflect what students have been taught.
Relay controls for choosing assessment question types and quantities

Teachers choose the question types and mix.

Before generating an assessment, teachers choose the types of questions and how many of each to include.

Each generated question shows the course material it draws from. Teachers can check the source, review the answer, and edit the question before sharing the assessment.

Relay was acquired by Discovery Education

Designed to grow with Discovery Education.

We built Relay so its AI model and visual design could evolve while preserving the workflow teachers knew. After the acquisition, we continued working on the product, adapting it for Discovery Education as it reached a larger audience.
