LessonDrop is an online teaching platform built for individual tutors and small teaching businesses. Create a professional booking page in minutes - add your session types, set your availability, configure packages and pricing, and share a single link with students.
Students see your page in their language (30 supported), browse your offerings, pick a time slot, and book. You get email confirmations, a dashboard to manage bookings, and Stripe payments built in.
Unlike Teachable or Thinkific, LessonDrop doesn't charge $39/month or take a cut of your revenue. The free tier is a real, working product. Not a demo. Pro unlocks unlimited booking pages, all 18 themes, analytics, and advanced features for $7/month.

ThreadMine.dev LessonDropLessonDrop's answer:
Built with React. Serverless architecture with global CDN.
LessonDrop's answer:
30 languages with automatic detection - the entire booking page displays in the student's language, not machine-translated. Auto currency detection across 30+ currencies. Built specifically for tutors and teachers, not repurposed from a general scheduling tool.
LessonDrop's answer:
$7/mo vs Calendly's $12/mo or Teachable's $39/mo. Free tier is a real product, not a trial. No revenue share on bookings. Tutor-specific features like parent/child booking, level and goals intake, session packages, and subject tagging that general scheduling tools don't offer.
LessonDrop's answer:
Solo tutors, language teachers, music instructors, academic coaches, and small teaching businesses. Anyone who teaches 1-on-1 or in small groups and needs a professional booking page without paying enterprise prices.
LessonDrop's answer:
Built by JRK Digital as part of a portfolio of 6 SaaS products. Every tool in the portfolio solves one problem well for one audience. LessonDrop exists because tutors were using Calendly or building WordPress sites when they just needed a booking page that speaks their students' language.
