Semrush is a mature, all-in-one SEO and digital marketing suite, while Gumshoe AI is a specialist AEO platform that shows you how AI engines like ChatGPT, Gemini, and Perplexity talk about your brand.

I tested both to help you figure out which one makes sense for your marketing stack, and whether you actually need both.

As a result of my research and hands-on testing, here is my take: these two tools solve fundamentally different problems. Semrush is the clear choice if you want to win in traditional search. Gumshoe is the tool to pick if you want to know whether AI-generated answers even mention you at all.

Semrush is the industry-standard SEO suite, and it has been for years.

But in 2026, a growing number of marketing teams are asking a different question: how do we show up when someone asks ChatGPT or Perplexity instead of Google?

That question is what Profound was built to answer. It is a dedicated Generative Engine Optimization (GEO) platform designed specifically to track and improve brand visibility across AI answer engines.

I spent several weeks testing both platforms side by side. What I found is that they solve fundamentally different problems, and comparing them head-to-head requires understanding what each one is actually built for.

Semrush is your operating system for Google-era search. Profound is your radar for AI-era conversations.

In this comparison, I’ll break down features, pricing, ideal use cases, and limitations so you can decide which one your team actually needs, or whether the answer is both.

With 900 million weekly active users and a valuation that recently hit $730 billion, ChatGPT is the most widely used AI product in history. But who actually owns it? The answer is more complicated than most people expect.

ChatGPT is not owned by Microsoft, despite what many assume. It is not controlled by a single billionaire founder, either.

The product belongs to OpenAI Group PBC, a public benefit corporation with one of the most unusual ownership structures in the technology industry.

This article breaks down who holds what, how the corporate structure evolved from a non-profit research lab to a $730 billion company, and what it all means for the future of the product hundreds of millions of people rely on every week.

MTCNN, short for Multitask Cascaded Convolutional Networks, is a face detection and alignment framework that finds faces in images and predicts five facial landmarks (eyes, nose, and mouth corners) in a single pipeline.

Introduced in 2016 by Kaipeng Zhang and colleagues, it became one of the most widely adopted face detectors in the deep learning era and remains in active use today.

If you have worked with face recognition, emotion analysis, or any computer vision pipeline that needs reliably cropped and aligned faces, there is a good chance MTCNN was somewhere in the stack.

This article breaks down how it works, where it fits in 2026, and when you should still consider using it over newer alternatives.

Perplexity and Gemini are two of the most capable AI research tools available in 2026, but they take very different approaches to helping you find, verify, and use information.

I’ve spent significant time testing both platforms to bring you a clear recommendation for your research workflow.

As a result of my testing, Perplexity is the better choice if your primary goal is fast, source-backed research with verifiable citations.

If you need deep analysis across large documents, multimodal reasoning, or tight integration with Google Workspace, Gemini is the stronger option.
