Building a Trademark Filing Success Predictor - Need Community Input - I will not promote

I'm developing a tool to help with trademark applications and success prediction. Before investing further in development, I'd love to hear from the community about your needs. Current pain points I've identified: • Uncertainty before filing • Time spent researching similar marks • Costly failed applications • Challenging office action responses Questions for the community: 1. What's your biggest challenge with trademark applications? 2. How do you currently decide whether to file? 3. What would make you trust a prediction tool? 4. What would you pay for higher certainty before filing? Looking to build something that helps reduce failed applications and saves time in the process. Need brutal feedback to see if this is a tool that would be utilized.
