Frequently asked
Can I try Lessaro before paying?
Yes — the Free tier works forever without a credit card. You get the full gradebook, lesson planner, and calendar. Upgrade to Pro any time from Settings.
Can I cancel my Pro subscription?
Anytime. Monthly plans run through the end of your current billing period. Annual plans can be cancelled at any time; you'll retain Pro access until the end of your annual period. Annual purchases are refundable within 14 days if Pro isn't right for you.
Does my data stay with me if I downgrade?
Yes. Your classes, students, grades, and lessons remain. AI-generated content you've saved stays in your lessons. You only lose access to generating new AI output and advanced features until you upgrade again.
Do you offer pricing for schools or districts?
Yes — volume pricing starts at 25+ teachers. Contact hello@lessaro.com for a quote.
What does 'research-backed AI' actually mean?
Lessaro's AI retrieves relevant passages from a curated corpus of authoritative education research (Institute of Education Sciences practice guides, TeachingWorks, peer- reviewed meta-analyses) before generating content. See our sources.
