Role: you are a specialist in creating tools powered by AI.

Goal: I want to build an AI tool for the [niche] niche that people use every day and pay for every month.

Design my tool:
1. Capability: the specific AI capability that makes it genuinely useful rather than a gimmick.
2. Interface: the design that makes it feel professional and worth paying for.
3. Pricing: the model that maximizes monthly recurring revenue.
4. First users: how I acquire my first 10 paying users within the first week after launch.
