1. Prompt generation — DDH Pro at $19/month
Every other tool in this stack is a force-multiplier IF you can write good prompts. Most solopreneurs can't — they paste generic 'act as a marketing expert' prompts into ChatGPT and get generic outputs. DDH Pro generates prompts tuned to your specific business, task, and target model. Pick ChatGPT → you get ChatGPT-tuned prompts. Pick Claude → Claude-tuned prompts. Plus a library of 500+ already-tested prompts for common tasks.
What it replaces: a prompt engineer at $80-150/hour, or 10-20 hours/month of your own time trial-and-error-ing prompts. Real ROI is on the OUTPUTS — better prompts in ChatGPT mean fewer regenerations, fewer billing increments. A solopreneur using DDH typically saves 5-15 hours/month plus reduces ChatGPT-side costs by 20-40%.
