About Miyako Stack

Practical reviews of AI tools and SaaS — tested in real work, from Miyako Island, Japan.

Who I am

I live on Miyako Island, in Okinawa Prefecture, Japan, and work for a construction consulting firm, where I lead the civil engineering design group. I'm also driving the adoption of AI tools across the company.

That job is where these reviews start. I judge tools on whether they hold up in real work — drafting, research, documentation, and team communication — not in a demo. Most English-language reviews come from full-time review sites or from marketers. Mine come from someone who has to decide whether a tool is worth rolling out to colleagues, and then live with that decision.

Why Miyako Island

Miyako is a small island in southern Okinawa, a long way from any tech hub. Working from here is a useful filter: a tool has to earn its place without an on-site vendor, a local support team, or a large IT department to lean on. If it's easy to adopt and dependable here, it will probably work for your team too.

What I review

AI tools are the main focus: writing, voice, and productivity software for professionals and small teams. I also cover marketing automation SaaS — email, funnels, and all-in-one platforms for small businesses — because the two categories increasingly overlap.

How I evaluate tools

• Hands-on where possible. If I've used a tool in real work, the article says what I used it for. If I haven't, the article says that too and relies on documented features, pricing, and terms.
• Criteria before conclusions. Each comparison sets out what it measures — price, output quality, limits, ease of adoption — before recommending anything.
• Honest cost comparisons. A cheaper plan that lacks an essential feature doesn't count as cheaper.
• No paid placements. Vendors can't pay to be reviewed or ranked. Some links are affiliate links; see the affiliate disclosure.
