As answered by people managing Codility and Lessona.ai.
Lessona.ai's answer:
Lessona is a complete lesson planning system built around the curriculum a teacher actually has to follow. Unlike credit based tools, every plan is unlimited. It works across all three planning horizons: long term annual overviews, medium term unit and term plans, and short term daily lessons. It also builds presentation ready slide decks with illustrations and labelled diagrams, handles differentiation, and never stores student names. Teachers who feel uncertain about technology can use it because it behaves like a planning companion, not a black box.
Lessona.ai's answer:
Most planning tools cap how much you can create or lock features behind credits. Lessona gives you unlimited plans for one simple price. It aligns to your region's current curriculum framework rather than a generic template, includes a calendar, supports differentiation, and produces ready to teach slide decks alongside the written plan. It was built with a practising primary teacher, so it fits the real rhythm of a classroom week rather than the workflow of a software company.
Lessona.ai's answer:
Primary, intermediate, and secondary school teachers who plan lessons every week and want to reclaim their evenings and weekends. The first market is New Zealand, with Australia, the United Kingdom, the United States, and Canada to follow. The core user is a classroom teacher who values their time, cares about curriculum alignment, and may be cautious about new technology.
Lessona.ai's answer:
Lessona was founded by Stephen and Emma Milner. Emma is a primary school teacher who lived the reality of spending evenings and weekends planning lessons, and Stephen builds the product around what she and her colleagues actually need. The goal is simple: give teachers back the hours that lesson planning quietly takes from their lives, while keeping every plan aligned to the curriculum they are required to teach.
Lessona.ai's answer:
Lessona is built with Next.js and TypeScript, styled with Tailwind CSS, and deployed on Vercel. Lesson and slide generation is powered by large language models from Anthropic and Google.
