Founder of WithTool, an independent site that tracks SaaS pricing changes for freelancers and small teams — every entry verified against the vendor's own pricing page with the date it was checked. I write hands-on reviews and comparisons of SEO and AI writing tools (Semrush, Mangools, Frase, NeuronWriter) and cover pricing shifts other sites miss because they never re-check old numbers.
