Chalk is an AI-powered platform that transforms complex educational content into clear, organized diagrams such as mind maps, concept maps, Venn diagrams, and storyboards to improve student understanding and retention. Designed for teachers, the platform leverages AI providers like OpenAI, Anthropic, and Google AI to generate visuals quickly, with features for differentiated instruction and accessibility support for students with dyslexia, ADHD, and autism. It also includes tools for tracking pupil progress and supporting Additional Support Needs (ASN) provision in schools.

Problem
Teachers often struggle to present complex or abstract educational content in ways that are clear and memorable for all students. Creating high-quality visual aids like diagrams, mind maps, and storyboards is time-consuming, and traditional text-heavy materials can hinder comprehension and retention, particularly for students with diverse learning needs such as dyslexia, ADHD, or autism.
Solution
Chalk provides an AI-powered platform that transforms complex educational content into beautiful, organized visuals, including mind maps, concept maps, Venn diagrams, and storyboards. Teachers input text prompts or content, and Chalk's AI generates structured diagrams in seconds, dramatically reducing lesson preparation time. The platform ensures visuals are designed based on pedagogical research—such as dual coding and cognitive load theory—to enhance retention, schema formation, and accessibility. Chalk also supports differentiated instruction by allowing fine-grained control over the detail and complexity of the visuals. For schools, Chalk offers additional features for tracking pupil progress and supporting Additional Support Needs (ASN) provision, ensuring that visual learning tools are aligned with individual student requirements.
Target Audience
Primary customers are teachers and educators in primary and secondary schools, as well as Multi-Academy Trusts (MATs) and educational institutions that need efficient tools for creating accessible visual learning materials and managing differentiated instruction or ASN provision.
Features
- AI-driven generation of multiple diagram types (mind maps, concept maps, Venn diagrams, storyboards) from text prompts
- Granular control over the level of detail in generated visuals to support differentiated learning resources
- Integration with multiple AI providers (OpenAI, Anthropic, Google AI, and Groq) for content generation, with a commitment not to use user data for training AI models
- Optional Chalk Access module for managing Additional Support Needs (ASN), including tracking pupil progress, support strategies, and staff qualifications, with read-only integrations to school information systems (SEEMiS, Wonde) and Trellis
- Pseudonymised processing of pupil data for AI requests, ensuring no directly identifying pupil data is sent to AI providers
- Content moderation systems to ensure all AI-generated content is appropriate for educational use
