What is the one AI tool you started using this year that actually replaced a paid subscription?

I feel like we are finally moving past the "AI can do everything" hype phase and into the "AI can actually do this one specific job really well" phase.

I recently canceled my premium subscription to a dedicated grammar and writing assistant because I realized I was getting better, more contextual results just by using a customized prompt in a standard LLM. It saves me about $15 a month, and the workflow is actually faster.

It made me wonder what else is out there in the AI community. What specific AI tool (or workflow) have you adopted recently that allowed you to cancel a traditional software subscription? Was it for coding, design, budgeting, or something else? I'd love to hear what everyone here on r/artificial is using to replace legacy software.?
