I went live with my AI icon generator tool, IconMage (https://iconmage.com), a little more than a month back. Before that it was in Beta and my main goal was to collect user feedback and work on it. Here are some lessons I share, which might help you in your journey too:
Feedback: Having just a support or contact email does not help. Users don't like writing emails.
Action: I used tawk.to for the support bot. It's free and the features are good enough for my use. I am now able to collect emails and answer queries of users without being actively online. It has a decent mobile app too.
Feedback: You just can't have a catchy tagline and image and expect users to pay for your product. You need to show what your product does and how, as soon as possible.
Action: Since users cannot access the "Create" page on IconMage without signing up, I have a short explainer video on how IconMage works on the homepage.
And, recently, and this was long overdue, I added an "Examples" page (https://iconmage.com/examples) to show how different IconMage styles behave on the same prompts.
Feedback: IconMage is for creating logos or app icons. It does not matter how good the UI is or how well I market it, users won't stay unless the quality is good enough to pay for.
Action: I contact my users on a regular (non-spammy) basis to check if they are satisfied with the icons they created and work on improving the styles whenever possible.
This is one of the things I got right the first time. I haven't had any paid users complain that the credits they've paid for haven't been worth it.
This is something I'm still struggling with, but I'm slowly getting it right. If you are confused about the channels from where to connect with the right audience, here's my advice:
These are the top 5 that come to my mind. What more would you like to add from your experience?
Hope it helps!
