Code

These are the working surfaces behind the products, grouped by the question each one was built to answer. Most are private, because the products are on the App Store and the trading system holds live keys, so a private row publishes its language and its dates and nothing else. Every detail page carries one piece of its actual code, chosen for the decision it shows. Nothing here is padding: duplicates, scratch experiments and dead ends were removed by name rather than listed.

Consumer AI8

Products where a model does something specific and checkable, rather than being the feature. The shipped ones are on the apps page; these are the rest of the attempts.

Distribution2

Building the thing is half of it. This is the other half — programmatic SEO and affiliate economics, where the engineering exists to answer a question about a market rather than a user.

  • FreelanceStack    Programmatic SEO: thirty tools scored on five weighted dimensions, generating 178 pages including 62 head-to-head comparisons.TypeScript · 5 months agoRead
  • pitchlessaiPRIVATE    Pitchless — scores Reddit posts for whether your product genuinely answers them, and drafts a reply worth sending.TypeScript · 5 months agoRead

Infrastructure2

Software other software depends on. Both of these exist because a guarantee was missing — that a retry cannot post twice, and that a bug which never throws still gets found.

  • Halyard    Social publishing infrastructure built around one rule: a retry must never post the same thing twice.TypeScript · todayRead
  • sentinelPRIVATE    Watches a deployed app for the bugs that do not announce themselves, and proves one is real before reporting it.TypeScript · 2 months agoRead

Prototypes4

Single-burst projects: an idea taken far enough to see whether it was worth continuing, and then not continued. Listed because the ratio is the honest part.
