Roland Hentschel
Founder & Lead Reviewer, AI Tool Radar
Freelance web developer and SEO consultant based in Herne, Germany. Founder of AI Tool Radar. Writes and verifies every review on this site personally.
From client websites to AI tool evaluation
Roland has been shipping production websites since the mid-2010s, originally as a freelance web developer serving small German businesses that needed something more robust than a page builder but smaller than an agency engagement. That middle-tier position is also where AI tools earn or lose their keep: the budgets are real, the time is tight, and a tool that wastes either gets dropped fast.
Over the years the practice grew from WordPress builds into full custom SaaS applications. Today Roland maintains several production platforms for clients, including a property-management system used by a real-estate administrator, a mobile field-report app for technicians on-site, a custom CRM and contact pipeline for a specialty manufacturer, and a client intake and lead-tracking system for an independent automotive damage assessor.
AI tools entered the stack naturally. Copilot in the editor, ChatGPT for spec review, Claude for long-form refactors, specialized writers for client content, image generators for mockups. Every tool in this site's directory has been tried in a real project before it gets a review.
AI Tool Radar launched in early 2026 because the English-language review landscape had an obvious problem: most of the coverage was written by people who had not actually used the tools, or had been paid not to say anything negative. The goal of this site is to be the place a busy professional can land on, read one guide, and make a confident decision.
