Decision snapshot

Is this worth validating?

Build this if

You already run paid creative cohorts and critique coordination is the clearest operational bottleneck.

Avoid this if

Your program is primarily self-paced video consumption with no peer review or portfolio outcome.

Validate first

Run one cohort of 10-20 learners and verify that at least 80% complete both assigned critiques without the instructor maintaining a separate tracker.

Problem and target customer

Why this exists

Customer problem

Creative cohort operators often coordinate lessons, submission deadlines, critique partners, and final showcases across video tools, forms, chat threads, and portfolio sites. Instructors lose visibility, while students receive uneven feedback and rebuild their work elsewhere after graduation.

Who pays

Independent design, writing, or multimedia educators who sell cohort-based programs and need one structured path from assignment to public showcase.

Business model

Per-cohort fee or monthly subscription for instructors, with student seats included in each cohort.

Editorial note

The narrow product is not another course library. Its value sits in the period between a learner uploading work and deciding that the work is ready to represent them publicly. That makes critique accountability and creator-controlled visibility the two decisions worth validating first.

Start with one creative discipline and one rubric format. Different media can share the same submission state model, but trying to support every file type, teaching style, and accreditation path in the pilot would hide whether structured peer feedback actually improves cohort completion.

Product goal

Who it serves and what it must change

Target user
A creative educator running paid, time-boxed cohorts and learners completing portfolio-oriented assignments.
Problem
The operator cannot reliably see who submitted, who still owes a critique, or which projects are ready for public display when those actions live in separate tools.
Measurable outcome
In a pilot cohort, every submission, assigned critique, revision, and publication decision is visible from one timeline without spreadsheet reconciliation.

MVP scope

What ships now and what waits

Included

  • Create a cohort with dates, modules, assignments, and enrolled learners.
  • Accept media-backed submissions and assign two peers for rubric-based critique.
  • Let learners revise work and publish instructor-approved projects to a public portfolio page.

Excluded

  • Live video classrooms and recorded-video hosting.
  • Automated grading or AI-written critiques.
  • A marketplace for discovering unrelated courses.

UX and user flow

Screens, actions, and states

Cohort Timeline

Show lessons, deadlines, submission status, and critique completion by learner.

Critique Desk

Submit feedbackRequest clarificationMark feedback addressed
Portfolio Editor

Turn selected submissions into ordered public case studies with creator-controlled visibility.

Choose a projectEdit project contextPublish portfolio

Primary flow

  1. An instructor opens enrollment and assigns the first brief.
  2. A learner uploads work before the deadline and receives two critique assignments.
  3. Peers submit rubric-based feedback; the learner posts a revision and response.
  4. The instructor approves the final project for the learner's public portfolio.

Loading, empty, and error states

  • Enrollment: draft, open, closed
  • Submission: not_started, submitted, revision_requested, approved
  • Critique: assigned, delivered, acknowledged
  • Portfolio project: private, ready, public

Critique

Records a peer assignment and structured feedback against the instructor's rubric.

Fields

PortfolioProject

Keeps the public narrative and visibility settings for an approved piece.

Fields

Relations
Belongs to one learner, References one approved submission

Business rules

  • Only enrolled learners may view cohort submissions, except projects explicitly published to a portfolio.
  • A learner cannot critique their own submission, and each submission receives no more than two active peer assignments.
  • Portfolio publication requires learner consent and an approved submission status.

Architecture and data flow

Components, integrations, and controls

Cohort web app

Serve instructor, learner, critique, and public portfolio experiences with role-aware routing.

Relational store

Persist enrollment, assignment, submission, critique, and publication state atomically.

Media service

Issue signed upload and download URLs for student work without exposing storage credentials.

Notification worker

Send deadline and critique reminders from an idempotent job queue.

Integrations

  • Object storage for submitted and portfolio media
  • Transactional email for invitations and deadlines

Data flow

  1. The client requests a signed upload URL, uploads media directly, then saves the returned object key with the submission.
  2. A submission transaction creates peer assignments while enforcing enrollment and self-review rules.
  3. Approval copies only portfolio metadata; the media remains referenced by its protected object key.

Failure handling

  • Keep an upload in draft until all media objects are confirmed
  • Retry email jobs without duplicating critique assignments
  • Allow an instructor to reassign a critique when a reviewer withdraws

Security

  • Enforce cohort membership on every private read
  • Use expiring signed media URLs
  • Keep public portfolio fields separate from private feedback

Rate limits

  • Limit signed upload requests per learner
  • Throttle reminder sends per cohort and deadline
  • Restrict repeated public portfolio edits

Deliverables and acceptance

Definition of done for the MVP

Deliverables

  • Responsive instructor and learner app
  • Cohort and critique permission model
  • Signed media upload flow
  • Public portfolio route
  • Seeded pilot cohort and automated tests

Acceptance criteria

  • An instructor can create a cohort, enroll three learners, assign a brief, and see each submission state.
  • The system assigns two eligible peers without assigning the author to their own work.
  • A learner can revise an approved project and publish it without exposing private critique text.
  • If a media upload fails, the submission stays editable and can be retried without creating a duplicate record.

Recommended stack

Enough technology for the first version

Web application

Next.js and TypeScript

One codebase can serve authenticated cohort tools and indexable public portfolios.

Database and auth

PostgreSQL with Auth.js

Relational constraints fit enrollments, reviewer eligibility, and submission states.

Media

Cloudflare R2

Direct signed uploads keep large creative files away from the application server.

Notifications

Resend with a database-backed job queue

Deadline reminders need retries and idempotency, not a separate automation platform.

Why this is sufficient

The first release needs reliable permissions and state transitions more than real-time collaboration. A relational monolith plus direct object uploads keeps the critique loop auditable and the public showcase simple.
