Tasukiba — AI Operations Secretary (Service Ended)

Note: this service has ended. The server has been shut down, so the “Try it” link above no longer works. The source code remains public in the GitHub repository as a portfolio piece. What follows describes the product as it was while live.

Before you go looking, the knowledge you need finds you

“We solved this on the last project.” “Those retro takeaways? Nobody remembers them.” — Until now, project knowledge only surfaced when you went looking for it.

Tasukiba is an AI operations secretary that remembers your work data — projects, knowledge, risks, issues, retrospectives. The moment you open a project, the past knowledge, risks, and retrospectives relevant to you right now line up automatically, ranked by relevance. And from the bottom-right of any screen, just ask in plain language for “past assets like this.” Search and delivery — together, they change how knowledge gets pulled out.

	Typical full-text search	Tasukiba
How you find it	You search by keyword	It surfaces on open + ask in plain language
Results	100+ hits to scroll through	The few most relevant, distilled
Wording gaps	”effort” ≠ “delay”	Linked by meaning, so both surface

Context, not characters. Search “bank” and full-text matching can’t tell a riverbank from a savings account — semantic search reads the surrounding context and returns the one you actually meant.

From “review 100 results by eye” to “decide from a handful.” Knowledge stops living in one person’s memory and accumulates as a team asset.

What’s in the Name

The name “Tasukiba (襷場)” comes from the place where one runner hands the relay baton (襷, tasuki) to the next. Tasukiba aims to be the place where the person who ran one leg can reliably hand the baton of insight to the next.

Meet the Mascot — “Tasuki Owl”

Tasukiba’s official mascot is the Tasuki Owl. Owls have long been associated with wisdom, memory, and watching over things even at night — values that map directly to the three pillars Tasukiba cares about.

• Wisdom & memory — Remember the insight you earned, and offer it back to whoever needs it now.
• Watching even at night — Keep an eye on every project so nothing slips through the cracks.
• A guardian’s calm presence — Stand quietly between your knowledge and the rest of the world, keeping both safe.

Every detail in the artwork carries meaning.

• Wings wrapped around a document — The core promise: protect the knowledge, then pass the baton forward.
• Shield with a keyhole — Tenant isolation, access control, and authentication that hold up for business use.
• Soft circular barrier in the background — A protected space where your project can run with confidence.

“Watch through the night. Protect what you know. Show it when it matters.” The Tasuki Owl is the friendly shape of that promise, quietly there beside you as you work.

Why an owl, out of every possible motif? I wrote about the meaning behind the name and the design in The Birth of the Tasuki Owl.
