We got tired of guessing what a prompt would cost.
Every provider hides pricing behind a table nobody reads until the invoice arrives. We wanted a place to paste a prompt, pick a model, and just see the number — before shipping, not after.
So we built stowly. No dashboards, no login, no seat pricing. Just the cost of your prompt, priced the same way it'll actually run.
Cost is where we started — Stowly is growing into the AI hub.
