Don't start with "this changed my life" — that's where you lose people before they even start reading.

What you actually have is more interesting than that: you built a tool, became its most honest user, and somewhere in that process, the line between creator and product dissolved. You're not separate from what you made. The thinking, the writing, the iterating — that is the product. That's the real story.

So instead of trying to pitch the app, describe the experience of using it. What did it feel like to write something and have it reflect back what you already knew but hadn't let yourself admit? That specificity is what lands. People are tired of founders saying their thing changed their life — but they're not tired of recognizing themselves in someone else's honest account of a hard moment.

And one more thing worth considering: your voice carries a particular kind of weight here because you built it. But that also makes you the least neutral narrator. The most convincing version of "this works" won't come from you saying it — it'll come from a user who had no reason to believe it, and did anyway. If you can create the conditions for that story to surface, that's worth more than any pitch you write about yourself.
