Architecture of Expert Reasoning

Expert time is scarce and generic AI lacks instructional grounding. Arch scales expert reasoning to every learner.

The education challenge

With AI and robotics, work is changing faster than we can train it.

Learners Waste Time

Learners click through lessons, memorize concepts but can't apply them. They fail certifications not from lack of intelligence or effort, but because critical reasoning connections are missing.

AI Tools Don't Align

Generic AI tutors give explanations that sound plausible but contradict certification standards. Inefficient scope or abstraction level. No grounding, no auditability, no control.

Experts Can't Scale

SMEs (Subject Matter Experts) can be the best teachers, but they can't provide feedback on thousands of practice attempts. Traditional scaling methods dilute quality.

For adults, having a mortgage, kids, full time job, education has to optimize for maximum mastery per unit learning effort.

Our Mission

How can we transform education

Arch enables experts to teach AI how they solve problems once, so AI can support thousands of learners with the same exact reasoning.

Expert Reasoning Scaled

Reasoning structure is extracted from lessons and training materials. Based on this index, educators define reasoning steps and conceptual connections required for a specific problem class. The system can draft problem/question pools with one click for each class.

Precision Diagnostics

Students receive targeted feedback showing exactly where their reasoning breaks down – not just 'incorrect answer' but which conceptual connection they're missing.

Fully Auditable

Every part of the internal index is explainable, traceable to exact source material. The system uses an advanced retrieval engine not a black-box. It provides reasoning primitives, lesson context and deterministic recommendation constraints to the generator model.

Grounded in Curriculum

Reasoning structure and exact source references provide orthogonal dimensions in AI grounding. These represent exactly the same reasoning paths and style educators use in lessons and practice problems.

The Feedback Difference

Context: Student practicing a problem and gets stuck.

Question: "I'm struggling to understand how neural networks learn. Can you explain backpropagation?"

Generic LLM

"Backpropagation is the fundamental algorithm used to train neural networks. It works by computing gradients of the loss function with respect to each weight by applying the chain rule, iterating backwards from the output layer to the input layer. The gradient descent optimizer then uses these gradients to update the weights..."

Arch*

"You understand chain rule and gradient descent individually, but struggle with how the chain rule applies across multiple network layers.

Complete chain:

...

Key insight: Each layer's gradient uses the previous layer's gradient. This is the propagation part, gradient information flows backward."

* Privacy respected: The model does not see student answers. It is enough to know the student successfully answered step 1, step 2 and failed step 3.

For Educators and SMEs

I

Initial setup: You teach the AI once

Upload high-quality core materials, key lessons, worked solutions (quality over quantity). Then Arch will guide you through the model building, review and optimization process. It can run with minimal interaction or offer maximum control by annotations, checkpoints and structural edits.

1

Create Problem classes*

Define a question or problem type as you usually do.

2

Author worked solution

Edit or upload step-by-step instructions on how to solve. It is important to provide detailed steps (system might help detect step boundaries).

3

Teach the AI your reasoning

For each step: "What concepts and reasoning are needed to solve this step?" Choose from a filtered list showing conceptual components and reasoning connections.

* Done once per problem type, not per problem.

High leverage, low overhead.

For Learners

1

Know What to Practice Next

No guesswork. No analysis paralysis. Clear next steps aligned with certification requirements.

2

Practice Problems

Work through practice questions and problems at your own pace.

3

Get Diagnostic Feedback

Receive precise feedback grounded in expert reasoning. Know exactly where your thinking breaks down.

Removes confusion and wasted effort, preserves productive struggle.

Learners build mastery faster with targeted guidance.

Core Approach

Why it works

Student already usse AI. The question is which they use – generic AI with no alignment to certification standards, or Arch grounded in expert's reasoning.

Fine-Tuned Models
  • Require hundreds of labeled examples
  • Need ML infrastructure & retraining
  • Black-box, can not audit reasoning
  • Fixing one error does not fix similar ones
  • Locks institutions into a specific model version
RAG Systems
  • Retrieve text, no reasoning model
  • Can not diagnose where thinking fails
  • No notion of expert connections
  • Surface content, can not guide thinking
Arch
  • Reasoning structure + lesson text
  • Works with small number of examples
  • Changes propagate instantly
  • Fully auditable & traceable
  • Model flexibility: upgrade, reduce costs or specialize without re-indexing

For Institutions & Decision-makers

Governance & Control

This system guides learning. Institutions retain complete control over curriculum design, certification standards, and pass/fail decisions.

  • Your experts define the curriculum
  • Your team controls certification criteria
  • System supports preparation, you control evaluation

Data Ownership

Institutions own their data. We process it. Single-tenant SaaS – dedicated instances, no shared infrastructure.

  • Institution is the data controller
  • Exam data protected via your own KMS keys
  • Practice data end-to-end encrypted
  • Your materials never leave your deployment

Quality Assurance

Helps with accreditation by making exams well-defined at cognitive and reasoning levels – but doesn't enforce standardization.

  • Clear alignment between objectives & assessment
  • Explicit reasoning pathways documented
  • Extracts structure from your actual corpus

Integration & Updates

Requires domain expert input for initial indexing and after major curiculum changes.

  • Small updates are efficient and immediate
  • No model retraining needed
  • Incremental re-index for ongoing curriculum changes

Target Institutions

Primary Use Cases

Internal Employee Development

Upskilling programs, role-based certifications, technical training pathways, and compliance requirements for your workforce

Customer & Partner Certification

Product certifications, partner enablement programs, and customer training that drives adoption and reduces support costs

Professional Credentialing Programs

License preparation, industry certifications, and continuing education for professions (Bootcamps, online or hybrid Master's programs, etc.)

Best fit for organizations with

  • Domain expertise accessible

    SMEs (part-time or consultant enough) who design curriculum, author training materials, and understand how learners develop mastery

  • Structured training programs

    Clear learning objectives, defined assessment standards, and measurable competency requirements

  • Existing training materials

    Lessons, worked solutions, practice problems, and documentation that reflect how your experts teach

  • Willingness to invest expert time upfront*

    Initial setup requires expert time to review and fine-tune indexing, define problem classes and reasoning structure.

* This initial investment creates long-term leverage as the model can auto-generate practice problems (educator review available) and guide 1000s of learners.

Academic institutions: Arch will be evaluated in formal educational (university) context. The architecture naturally fits to controlled applications where compliance and auditability are just as important as performance.

Safe space

Privacy is a feature, not a policy

Adult learners worry about predictive profiling, hidden performance evaluations, and risk scores. Cognitive science shows, the lack of trust impedes cognition and fosters disengagement, avoidance and cheating.

Arch provides an E2EE safe space to practice, experiment and fail.

Privacy Architecture

Tier 1

Exam Data (for certification)

Stored for compliance and certification. Clearly distinguished with explicit privacy policies.

  • Required for credentialing and compliance
  • Protected via the institution's KMS keys
  • Not shared outside of Institution's privacy policy
Tier 2

Practice Data

End-to-end encrypted. Opt-out available. Hard-deletable by learners.

  • E2EE practice data
  • Used for precision learning
  • Impossible to share with managers
Tier 3

AI Conversations

Never processed for system adaptation. Hard-deletable by learners anytime.

  • Only for conversation history (E2EE storage)
  • Full learner control
  • Not used for model training

Why This Matters

Most adaptive learning systems surveil every interaction to build learner models. This enables profiling, learner analytics dashboards, that erodes trust and psychological safety.

Our architecture achieves precision diagnostics by processing only practice and exam evidence. Minimal data processing that can run in browser or TEE with full E2EE.

What This Means

  • Learners control their practice data, delete AI conversations anytime
  • Institutions get what they need for compliance with clear separation
  • No surveillance, no profiling, no behavioral modeling

Result: Learners practice more honestly when they are not being watched.
