Your Office.
Your Data Freedom.
Vertex Office is a flagship suite designed to boost your productivity. Security is entirely in your hands — powered by an optional, completely non-trainable local AI engine where you define the boundary.
Tailored by You.
Adjustable System Prompts.
We envision users harnessing AI on their own terms. Take complete control over how the AI interacts with your spreadsheets and drafting workflows.
Excel Formula Generation
Customize the system prompt to instruct the AI exactly how to structure complex spreadsheet formulas, financial modeling functions, and data macros.
> System: "Act as a senior quantitative financial analyst. When given plain text, output clean, efficient Excel formulas without explanatory filler..."
Writer Drafting & Editing
Tune the drafting engine for contracts, documentation, or executive summaries. Modify default behaviors to match your personal or corporate tone.
> System: "Draft strictly in concise, professional legal phrasing. Avoid redundant phrasing and structure all paragraphs with clear headers."
Seamless Setup.

You Decide.
You Control.
Most modern AI tools feed on your proprietary documents. Vertex hands the controls back to you — what happens with your data is entirely your decision.
-
Non-Trainable AI — By Design The AI engine never trains on your data and never adjusts its weights from your documents. That's how we built it — the rest is up to you.
-
You Set the Boundary You have full visibility into where and how data flows. You decide what stays local and what connects — the security boundary is yours to define.
-
Audit It Yourself The codebase is available for inspection. Don't take our word for it — verify how the software handles your data.
