Built from the therapy room. Designed for the classroom.

LessPrep was built by an RBT and autism specialist with 15 years of hands-on experience across ABA therapy, behavior intervention, Qualified Intellectual Disabilities Professional (QIDP) roles, public school tutoring, and private work with children on the autism spectrum. Every feature exists because it was needed in a real session, with a real learner.

Important: Core creation workflows rely on GPU-accelerated AI image generation. A Vulkan 1.1-compatible GPU with 8 GB+ VRAM is required for intended use. Most modern NVIDIA and AMD GPUs with 8 GB+ VRAM are supported; Intel Arc A750 and A770 are also supported.

No Subscription. No Cloud. No Internet. Ever.

Student data never leaves your machine. LessPrep runs 100% offline using on-device AI — no account required, no monthly fee, no privacy tradeoffs. For schools, clinics, and therapy settings where cloud tools are a compliance concern, this is the point.
