Overview

TKAWEN Knowledge powers learning and credentialing for product teams, schools, training organizations, and certification authorities:

• LMS — lessons, assignments, quizzes, progress tracking
• Certificates — QR-verifiable, tamper-proof via SHA-256 hashing
• Trainer marketplace — unified instructor accounts under TKAWEN ID
• Skills taxonomy — indexed skill tree linking courses to job market signals
• AI Tutors — context-bound LLM tutors that won’t hallucinate outside the syllabus

Replaces Teachable, Coursera, Credly.

Verifiable certificate

Every certificate is:

• Signed with SHA-256 hash
• Permanently valid (unless explicitly revoked)
• Verifiable without an account — anyone scanning the QR gets a public page
• Issued under your organisation’s branding, not TKAWEN’s

The public verification page at verify.tkawen.com/cert_8xk2 shows:

• Issuing organisation
• Issue date
• Skills acquired
• Validity state (live / revoked)
• TKAWEN digital signature

AI Tutor

curl -X POST https://api.tkawen.com/v1/knowledge/ai-tutor \
  -H "Authorization: Bearer $TKAWEN_KEY" \
  -d '{
    "course_id": "crs_abc",
    "question": "Explain the difference between useState and useReducer.",
    "language": "en"
  }'

The AI Tutor responds based on course content only — no hallucination outside the syllabus. Student data stays within your organisation’s tenant.
