Built for B2B Marketers Who Hate “Excel Hell”

Hi, I’m Nikolai. Welcome to the pSEO Toolbox.
I am not a full-time software engineer but a B2B Operations Specialist working in the foreign trade industry, just like many of you.
My daily job involves building websites, managing Google Ads, and optimizing SEO for industrial products. For years, I faced a recurring nightmare: The Spreadsheet.
The Origin Story
Every time I needed to plan a site architecture for a new product line, I found myself staring at Excel. I had to manually combine columns of data to generate long-tail keywords:
- Column A: Manufacturer, Supplier, Factory…
- Column B: CNC Machining, Steel Pipes, Injection Molding…
- Column C: USA, China, Germany…
I spent hours fighting with =CONCATENATE formulas, fixing formatting errors, and copy-pasting data. I looked for tools to automate this, but they were either expensive SaaS subscriptions ($99/mo) or ad-infested pages from the 1990s.
So, I decided to build the tool I wished existed.
The Philosophy: Fast, Private, & Free
I built pSEO Toolbox with three core principles:
- Privacy First: As a B2B marketer, I know client data is sensitive. That’s why this entire site runs on Vanilla JavaScript. All data processing happens locally in your browser. I never see your keywords.
- Speed & Simplicity: No logins. No databases. No “Sign up to see results.” Just open the page and get your work done.
- Dark Mode Native: Because SEOs and developers often work late at night. Your eyes deserve a break.
