Siena Tech

Small online tools that do one job well.

Siena Tech is an independent software studio. We build focused web tools for jobs that should be simple but aren't, like moving years of notes from one platform to another.

Tools

Each tool is built around a single task, with clear pricing and no account to set up.

NotePorter

Moves your OneNote notebooks into Google Drive. Every page becomes an editable Google Doc, organized by notebook and section, so years of notes arrive ready to use.

Built for people and companies switching from Microsoft 365 to Google Workspace, and for students keeping their notes after graduation.

How we build

The same rules apply to every tool we make.

One job, done properly

A tool should solve one problem completely, including the awkward cases, rather than many problems halfway.

Your data stays yours

We use official sign-in from Microsoft and Google, never see your passwords, and delete access as soon as a job is done.

Honest about limits

Each tool says plainly what it can't do yet, and tells you exactly which items it couldn't handle.
