Let's rank the most hyped AI tools from S to D tier. First up, you got ChatGPT. Most people use it at a surface level, and if you do that, it's only D tier. But when you connect it with MCPs and you're using its agentic workflows and you're using its agents, it becomes S tier. Next, you got Claude. It's been our go-to for my team from a coding standpoint and from a writing standpoint. It's great at that, but it kind of suffers when it comes to context-heavy projects. So I would put that in A tier. Now you got Cursor. If you're building anything with agents or code, this is absolutely elite. In fact, some of the biggest companies in the world, they are all using Cursor. NVIDIA is an example. S tier. Next up, you got Perplexity, which is perfect for fast research. When I want to do fast research or deep research on particular stocks or businesses or content strategies, it is the thing that I use the most when it comes to research. B tier. Now you got writing tool Jasper. It's been around for a while, but it feels like it's still stuck in 2022. The templates are okay, but the outputs just average. D tier. Super Whisper. Super Whisper is amazing for dictating what you want done, meaning that whatever I want to write, whatever I want to create, instead of me having to write it all out, and type it all out. I can now dictate it using my natural language and I can have agents created for me from scratch. A tier. And lastly, I got Granola AI. Granola is fantastic for taking notes. It gives me an entire transcript from all the conversations I'm having and it summarizes all the notes. A tier. Follow for more AI marketing breakdowns. What's actually working, what's not, and what's worth your time.
