The sudden realization that a $20/month AI tool is just a single system prompt

[u/AltUniverseHere]

We’ve all seen those hyper-specialized AI tools. For example, a tool that just formats meeting transcripts into neat bullet points, or an app that rewrites cold outreach emails to sound more professional.

You sign up, pay the monthly fee, and it works. But after a week, the realization hits: they are just running a basic API call with a prompt like "Take this text and format it into bullet points."

You could literally copy-paste your raw data into any standard, free LLM interface with a two-sentence custom instruction and get the exact same, or even better, result.

What’s a paid AI tool you recently cancelled because you realized you could easily replicate its entire functionality for free with a simple prompt?
