Latter Study
A competent technical user can reproduce the core app (LLM-backed lesson builder, Q&A, daily prompts) in about a week; Latter Study's visible value appears to be product polish and community rather than irreproducible data or infrastructure.

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 Latter Study alternatives, with the arithmetic →
What a replacement has to do
- User picks a topic or scripture → backend calls an LLM with prompt templates → generate a lesson outline or answer → store result and show in app; scheduled job pushes a daily prompt.
What it still won’t have
- Polished native mobile apps and app-store-level UX polish
- Any proprietary doctrinal review or editorial curation the vendor provides
- Built community, social features, or existing member base
- Brand trust and ongoing product improvements from the vendor
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-tenant web app (Next.js + TypeScript frontend, Node/Express backend, Postgres database) that replicates the core Latter Study features: 1) Lesson Builder: accept topic or scripture, call an LLM (configurable OpenAI-compatible API) with prompt templates, store and present a structured lesson outline; 2) Gospel Q&A: accept freeform questions, call the same LLM, store answers with source text and timestamps; 3) Daily Study Seeds: implement a scheduled worker (cron or serverless job) to generate and store one short prompt per user per day and a simple delivery UI; 4) Authentication (email/password) and basic profile settings; 5) Admin dashboard to view logs, regenerate AI outputs, and manage prompt templates. Out of scope: native mobile apps, multi-tenant billing, social/community feeds, and editorial doctrinal review workflows. Include input validation, rate-limiting, retries for API failures, logging, basic automated tests for critical routes, and a Dockerfile + deployment instructions for a VPS or managed container host.

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.
