Desktop apps
Fast Windows software for the documents and decisions people work with every day, with AI and workflows that run offline.

Independent software studio
Samurai Dynasty Online builds desktop and mobile apps that bring AI into everyday jobs, so the work gets done faster and with less busywork. Our tools run on your own hardware, and your files stay yours.
The studio
Samurai Dynasty Online is a founder-led studio that makes practical software for real jobs. We start from the task in front of someone, an estimate to finish or a set of drawings to check, and build the tool that takes the repetitive parts off their plate. AI is part of that toolkit, used where it saves time and always shown with its sources.
Fast Windows software for the documents and decisions people work with every day, with AI and workflows that run offline.
Android apps that take the same work into the field, so what was started at the desk can be checked and finished on site.
Language models, document search and text recognition built into the tools themselves, with every answer tied to the source it came from.
Products
Coming soon · v1
A desktop PDF editor for construction professionals. Mark up sheets, take off quantities, build the schedule and ask questions of the specs, with AI that runs offline on a model you choose and cites the passage behind every answer from your documents. An Android field app takes the same set to the job site.

Our approach
We put AI where it removes real effort: reading a hundred-page spec, tallying quantities, keeping a schedule current. It runs on the user's own computer, says where each answer came from, and asks instead of guessing when something is missing.
Operating principles
Make the job easier, not the software bigger.
Never guess: ask, or show the source.
Keep people's work on their own machines.
Ship steadily and say plainly what the software does.
