AI & Product Daily

A daily AI news digest that a pipeline I built writes and sends.

The problem

Staying current in AI is a second job. The useful signal is scattered across launch posts, practitioner videos, and forum threads, and most of it decays inside a day.

So people either skim nothing or lose an hour to it. Neither one scales to a team.

What I did

I built a pipeline that assembles a morning digest and sends it: what practitioners are shipping, plus the news worth five minutes.

Sources are read, checked against what already went out, and ranked before anything is written. Repeats are the fastest way to lose a daily reader.

A four stage flow, sources then select then compose then deliver. Everything delivered is written back to a memory store, which the select stage reads before the next edition.

The left-to-right path is the easy half; any newsletter has one. The loop is what makes it survivable: everything that ships is written back, so the no-repeat guarantee holds without anyone remembering what went out yesterday.

The format is fixed on purpose. Same sections, same order, every day, so reading it becomes a habit instead of a decision.

It runs on a schedule rather than on me finding a spare hour. That is the only reason a daily thing survives past week two.

In July I moved distribution onto an Apple Directory group, so people request access and get added without coming through me.

Outcome

87 editions between June 24 and October 5, 2026.

The group is the part I would point at. A useful thing that depends on me being the door stops being useful. This one no longer does.
