Products

We build what we use, then publish it.

Of the tools A&A runs on internally, here are the two you can look at — or use — right now.

OSS · Public

claude-second-brain-jp

A Claude Code plugin that grows a record of decisions into a knowledge base, built on Obsidian — completely free to use. Source is public on GitHub, MIT licensed, currently at v0.1.0. A&A uses the same plugin to produce this site’s own articles and diagrams.

Real client engagement · In production at A&A (limited availability)

Multi-store MEO operations SaaS

This SaaS grew out of a real client engagement and is operated in production by A&A; the client name is withheld for confidentiality. It turns Google Business Profile operations across multiple stores — posts, review replies, and monthly reporting — into an agent workflow, with a human approval step on every AI output. It is currently offered to a limited set of operator agencies.

Demo video (real SaaS screens)

The Second Brain approach — how the knowledge base is actually built — is explained in detail on its own page.

Products still in development will be added here once they’re ready to show.
