PlanSpark

AI-powered lesson plan generator for K-12 educators.

I built PlanSpark to help teachers plan faster and walk into class more prepared.

I built PlanSpark because lesson planning can feel repetitive, scattered, and more time-consuming than it should be. I am married to an elementary school teacher with more than 30 years of experience, and watching the amount of work that happens before and after the school day gave me a much clearer picture of how much time goes into preparing strong instruction.

The feature I am most excited about is the Lesson Plan Simulator. Teachers can create a profile for a real class and get a preview of how a lesson might land before they ever teach it. That idea felt especially valuable to me because it moves beyond content generation and into actual classroom preparation.

I also wanted PlanSpark to stay grounded in the day-to-day work of teaching. That is why the platform reaches beyond lesson creation into assessments, reading support, parent communication, and special education tasks. The goal was never to build a flashy AI demo. It was to build something teachers could come back to again and again because it genuinely helps.

What it does

  1. 1

    Break down academic standards into clearer teaching targets and student-friendly language.

  2. 2

    Generate lesson plans and move into aligned assessments and support materials from the same workflow.

  3. 3

    Create class profiles and simulate a lesson to spot pacing issues, likely struggles, and engagement concerns ahead of time.

  4. 4

    Build assessments, rubrics, worksheets, presentations, and student feedback more quickly.

  5. 5

    Support related classroom needs like parent communication, text rewriting, and special education documentation.

Who it's for

K-12 teachers, instructional coaches, PLC teams, special education staff, and school teams who need faster planning without giving up alignment, differentiation, or classroom practicality.

How it's built

I built PlanSpark as a Blazor and .NET application backed by Azure and OpenAI services. I wanted the product to support the real work teachers do every week: planning lessons, unpacking standards, creating assessments, supporting reading instruction, and handling special education tasks.

Why it matters

What matters most to me about PlanSpark is that it tries to respect a teacher's time. Instead of throwing a bunch of disconnected AI features onto a page, I wanted to build a tool that feels organized around real classroom work and helps teachers move from idea to instruction with less friction.
