  1. What would stop you from trying Ninjachat AI (https://ninjachat.ai) this month? Be specific about how you handle this today. Also say the maximum you would pay per month in USD (0 if nothing).

    The biggest thing that would stop me is the potential for information overload. We already switch between Claude and Gemini based on specific needs like microcopy or summarizing interviews, and adding another tool, even one that consolidates, requires careful consideration of workflow integration. I'd need to see how it handles the specific nuances of our research notes and if it genuinely simplifies the process rather than adding another layer. Currently, I manage this by having specific use cases for each tool and a clear mental model of when to use which. Regarding pricing, I'd be willing to pay up to $15 per month, but that would be on a personal, not company, budget, and only if it demonstrably saves me significant time or effort.
