Learning and careers decision

Vellum

A competent developer can recreate the core interview→draft→publish workflow and Stripe storefront in about a week using existing OSS pieces, but reproducing Vellum’s marketplace, growth programs, analytics polish, and community features is non-trivial and likely not worth fully rebuilding.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Vellum alternatives, with the arithmetic →

What a replacement has to do

  • Record an interview or type answers → transcribe → generate structured course (modules/lessons) with AI → edit content → optionally record lessons with teleprompter → publish course page and accept payments via Stripe.

What it still won’t have

  • Built-in marketplace and cross-creator storefront/traffic
  • Promotional features tied to platform (reel views refund program)
  • Polished analytics, priority support, and community spaces integrated across courses
  • Any proprietary editorial/UX polish and iterative product improvements from the vendor

What remains hard

  • Product polish and ongoing maintenance

Runnable build prompt

Not run yet
Build a minimal self-hosted course-creation service in Next.js + TypeScript, Postgres, and Node backend. Core features in scope: (1) in-browser audio recording and upload; (2) server-side transcription using OpenAI/Whisper-compatible model; (3) LLM orchestration to generate modules, lessons, and scripted teleprompter text from transcripts; (4) editable lesson editor with inline AI rewrite actions and versioning; (5) teleprompter UI and lesson video attachment flow; (6) Stripe integration for one-time purchases and a simple storefront; (7) deployable container + automated backups and basic analytics. Out of scope: multi-creator marketplace, community spaces, advanced marketing tooling, reel-credit program, and custom domains. Include error handling, input validation, authentication (email), unit tests for critical orchestration logic, and deployment scripts (Docker + cloud provider instructions).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
