Problem

Generic AI feedback creates more questions than answers

Foundation models lack context: no rubrics, no students, no standards. AI grading becomes a black box teachers can't explain.

Solution

Assessment you can explain. Results you can trust.

TrustAI layers your rubrics, materials, and teaching style over foundation models. Every grade comes with a plain-language explanation anyone can read.

How It Works

Four steps. Full transparency.

Our goal is to encourage safe, transparent learning with AI for students and teachers alike.

Step 1

Teacher Creates Assignment

Set up your assignment, upload course materials, and generate a rubric.

  • Choose assignment type: Essay, Speech, or Coding (coming soon!)
  • Upload PDFs, syllabi, or paste your assignment prompt
  • Auto-generate a rubric aligned to your standards
  • Share with students via a short link

Step 2

Students Submit Work

Students complete assignments in the platform with an optional AI helper.

  • Essay: written response graded against your rubric
  • Speech: AI conversation assessed for verbal fluency
  • Coding: code review and feedback (coming soon!)

Step 3

TrustAI Analyzes Every Submission

Four tools work together to surface insights while maintaining full transparency.

  • Writing Assessment: AI use signals and originality
  • Rubric Generator: standard-aligned criteria
  • Knowledge Assistant: answers from your course materials (RAG)
  • Conversation Avatar: oral formative assessment with AI

Step 4

Teacher Reviews & Approves

TrustAI drafts feedback and flags signals. Teachers approve, edit, and override.

  • Review AI-drafted comments per rubric criterion
  • See AI-use signals with plain-language explanations
  • Edit any suggestion with a single click
  • Full audit trail: every AI/teacher decision is logged
