Common questions
How is LESSO different from ChatGPT?
ChatGPT responds when you prompt it — you still do the thinking. LESSO works ahead of time, preparing your lessons before you ask, in your school's style and on your curriculum. You review and approve, not create and fix.
Will LESSO actually save me time, or just add another tool to manage?
LESSO replaces your lesson planner, slide editor, worksheet generator, and communications tools — all in one place. For less than 25p a day, you get everything back that other tools have taken from your evenings.
What if my lessons need to match my school's specific style?
LESSO learns your school's BrandKit — your logo, colours, fonts, and teaching style. Every document it produces is on brand, right first time. SLT-ready. Always.
Is LESSO safe to use with school data?
Yes. LESSO is UK-GDPR compliant and built specifically for UK schools. Your data and your pupils' data are never used for training models or shared with third parties.
How much does LESSO cost after the founding cohort period?
Founding teachers receive free access during the cohort period. After that, LESSO plans start from £7/month — less than 25p a day to replace your lesson planner, slide editor, and comms tools combined.
