Pruuva

Your students submitted the work.Do they understand it?

Pruuva adds a short, adaptive follow-up to any work students submit, from essays to code to projects, and produces rubric-linked evidence of what each student actually understands. No detection. No surveillance. No course redesign.

Vertical Integration
as Strategic Inevitability:
A Tesla case study

§2 Theoretical framework. Drawing on transaction cost economics (Williamson, 1985), the integration decision can be framed as a response to asset specificity and small-numbers bargaining hazards.

In Tesla's case, the most cited driver is battery cell supply, which exhibits both long-cycle capex requirements and severe lead-time risk during the 2017–2022 expansion.

§3 Empirical pattern. Cross-referencing 10-K filings against industry benchmarks, the in-house share of cell production rises from 0% in 2015 to a projected 56% by 2028…

WHAT YOU GET

A clearer way to review AI-era student work

Pruuva turns an existing assignment into a structured review: collect the work, ask the student to explain it, inspect the evidence, and keep a record that supports the final decision.

Start with the submitted work

Use the essays, reports, files, code, repositories, and mixed assessments students already turn in. No course redesign is required.

Keep AI suggestions inspectable

AI-assisted grading stays tied to rubrics, student responses, execution evidence, and confidence levels so you can inspect the basis for every recommendation.

Ask students to explain it

Submission-specific oral, video, or text follow-ups ask students to explain, adapt, and reason from the work they turned in.

Review the evidence in one place

See rubric-level understanding ratings, quoted transcript excerpts, integrity signals, strengths, weaknesses, and source-linked rationale in one report.

Make the decision with context

Use side-by-side submission review, evidence panels, rubric scoring, annotations, AI suggestions, and teacher overrides in one grading flow.

Preserve a defensible record

Each completed workflow can preserve identity, artifact, follow-up, rubric evidence, integrity context, and teacher judgment as a durable evidence event.

THE PROBLEM

Submitted work is no longer enough evidence

The AI-era question is not just who produced the output. It is whether the human can demonstrate the capability the output claims to represent.

AI made polished output cheap

Essays, reports, code, plans, and explanations can now be generated and revised faster than institutions can verify them.

Detection answers the wrong question

AI detectors guess whether text looks machine-generated. They do not show whether the person can explain the work, adapt it, or reason from it.

Capability evidence is expensive

A direct conversation, rubric review, session audit, and evidence record would be ideal for every student. Manually, that does not scale.

THE EVIDENCE LOOP

From submitted work to capability evidence

Pruuva is not an AI detector or a proctoring wrapper. It is a structured workflow for producing evidence that a human can defend the capability their work claims.

01

Artifact

What the student produced

The paper, project, file, code, repository, or written response becomes the starting evidence.

02

Probe

How they explain it

Adaptive follow-ups test reasoning, tradeoffs, corrections, transfer, and depth of understanding.

03

Rubric

How capability is evaluated

Findings map to rubric dimensions so evidence supports the grading decision instructors actually need to make.

04

Integrity

Whether the session is reliable

Consent, identity, timing, transcript quality, and session signals stay separate from comprehension findings.

05

Judgment

What the instructor decides

Pruuva suggests and organizes evidence. Teachers review, adjust, override, and finalize the grade.

06

Evidence event

What can be inspected later

A durable record links learner identity, task, artifact, probe, report, session context, and teacher judgment.

HOW IT WORKS

The loop from output to evidence

Pruuva brings the submitted work, adaptive follow-up, rubric evidence, and instructor review into one assessment flow. You get a clearer basis for grading without rebuilding the assignment.

  1. 01Define the task, rubric, and evidence policy

    Create an assessment, choose supported artifact and question types, set rubric dimensions, configure access, and decide whether students demonstrate understanding through text, audio, or video.

  2. 02Students submit work and demonstrate capability

    Students submit through a link or roster-gated portal. Pruuva probes specific claims, choices, code paths, sources, or methods so the student can explain the work in their own words.

  3. 03Review evidence and make the final judgment

    The evidence report connects transcript excerpts, rubric ratings, integrity signals, and AI suggestions. Teachers review, annotate, override, grade, and export the record.

INSIDE THE ASSESSMENT

Not generic questions.
Evidence from their work.

Every probe starts from the student's own work: their claims, methods, sources, code paths, and decisions. Students respond through the mode the instructor configures, and the resulting evidence stays linked to rubric dimensions.

Reads the full artifactParses claims, evidence, methodology, reasoning, files, code decisions, or project structure.
Generates artifact-specific probesEach question targets concrete passages, choices, or claims with configurable depth and focus areas.
Captures demonstrated understandingStudents respond via the configured text, audio, or video mode with transcripts and session context.
Builds an evidence recordRubric ratings, quoted excerpts, integrity signals, strengths, weaknesses, and teacher decisions stay connected.
STUDENT SUBMISSION

The study employs a mixed-methods design integrating quantitative survey instruments with semi-structured interviews to triangulate findings.

Sample size determined via power analysis (α=.05, β=.80) yielding a minimum n of 84 per arm.

Findings consistently suggest that institutions with greater perceived credibility anchor expectations more effectively…

LIVE ASSESSMENT
PRUUVA
You mention a power analysis with α=.05, β=.80. Where did those parameters come from?
STUDENT
Um, alpha is just standard convention. The beta… honestly I think I pulled it from a template.
PRUUVA · FOLLOW-UP
Let's stay there. What does β=.80 actually mean in plain English?
STUDENT
It's the probability of detecting an effect if one is really there. Eighty percent.
PRUUVA · FOLLOW-UP
Good. So why .80 and not .90?
speaking…

How it works

Scans text for AI-generated patterns using statistical analysis

Artifact-specific probes tied to the student’s own submission and rubric

What it measures

Probability that text was AI-generated (binary yes/no)

Demonstrated understanding mapped to rubric dimensions with quoted evidence

False positives

Flags non-native speakers and neurodiverse students at disproportionate rates

Designed to evaluate demonstrated understanding instead of writing-style patterns

Student experience

Accusatory. Students feel surveilled and guilty until proven innocent

Fair. Students demonstrate what they know in their own voice

Actionable output

A percentage score with no pedagogical value

Evidence report with per-dimension findings, source excerpts, and review context

FAQ

Things people ask

Most questions come from one place: making sure this is fair to students. We obsess about that too.
