Supplements AI
A competent developer can reproduce a useful core (questionnaire, catalog, schedule, reminders, charts) in a few weeks, but the full product value relies on curated content, polished native apps, and an existing user base that are costly to match.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User completes a questionnaire -> backend estimates nutrient gaps -> user selects/adds supplements -> system generates a timed supplement schedule and reminders -> user logs adherence and sees progress charts and suggestions.
What it still won’t have
- Native mobile apps and polished app-store presence
- Proprietary AI tuning and curated 200+ supplement profiles with editorial content
- Existing user base, ratings, and aggregated reviews
- Polish and UX refinements from production usage (repeat edge-case fixes)
What remains hard
- Brand trust

Runnable build prompt
Build a single-tenant web PWA supplement tracker using Next.js (React) + Node/Express backend, Postgres for data, Redis for scheduled jobs, and Firebase Cloud Messaging + SendGrid for reminders. Core features in scope: (1) onboarding questionnaire and backend rules engine to estimate 18 nutrient probabilities, (2) seedable supplement catalog (~200 items) with search/filters and interaction metadata, (3) schedule generator that places supplements around meals/sleep/exercise and persists reminder events, (4) push/email reminder delivery and simple 'taken/missed' logging, (5) day-by-day charts and CSV export of logs, (6) basic auth, user settings and privacy controls. Out of scope: training custom ML models, native App Store builds, community reviews, and third-party integrations beyond push/email. Include input validation, retry logic for notifications, background job monitoring, basic unit/integration tests, and deployment scripts (Docker + cloud host).
How we checked
How the score was reached
- Partly verdict base52
- 3/3 assessment runs agreed+4
- Evidence score56
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.
