Chalkie is a UK-based edtech startup focused squarely on one of the most painful parts of teaching: lesson preparation. The platform lets a teacher type in a topic, select a curriculum, and guide the AI to produce a complete, classroom-ready lesson in seconds, including professionally designed teaching materials and differentiated activity sheets for students of varying abilities.
The product offers three creation modes built around how teachers actually plan. Lessons generate a single standalone session, Lesson Series build multi-session units with sensible scaffolding, and Worksheets produce standalone practice materials. Generated lessons include slides with learning objectives, key vocabulary, images, activities, and even suggested YouTube clips, and everything is fully editable and exportable to Google Slides, PowerPoint, or PDF so teachers can adapt the output to their own style and classroom.
A key strength is international curriculum coverage. Chalkie aligns to UK standards, US standards including Common Core (CCSS) and state-specific standards, and Australian curricula, which lets it serve teachers across multiple English-speaking education systems from a single product. This breadth, combined with a generous free tier, has driven rapid global adoption: the company reports more than 500,000 teachers and over 10 million students reached worldwide, with teachers self-reporting average time savings of around five hours per week and 90% strongly agreeing that Chalkie contributes to their long-term professional well-being.
Chalkie pursues a freemium model with a forever-free plan offering a handful of resources per week, a Pro plan at roughly $80 per year, and a higher-tier Max plan with more capacity and advanced features. The company closed a $4 million seed funding round led by Triple Point Ventures, capital it is using to expand curriculum coverage, deepen its feature set, and scale globally as demand for AI lesson-planning tools accelerates. Chalkie's positioning as a fast, affordable, standards-aligned planning assistant places it directly in the teacher-copilot category that has attracted significant venture interest.
