Just my opinion, I have experience using similar tools, so this is what I observed.

Pros:
- Can add prompts to track
- Can add competitors to track
- Visually appealing

Cons:
- Adding branded prompts will artificially boost your brand's share of voice, which is not accurate. There should be a clear branded versus non-branded filter when showing the funnel and share of voice, so you can see the real share excluding brand terms.
- Some citations are not picked up at all. For example, I entered a domain and a prompt for that domain; in Google search and overviews, the same brand ranks number one and is cited on Google overviews for their site and YouTube, yet Visby does not detect this.
- Content generation feels very generic and is basically just AI-created. I am not sure this content would make a difference if added to a site, especially since it is all AI content. The suggested content is unlikely to rank because it chooses titles already covered by other brands and saturated, instead of offering a unique take or point.
- Most suggested prompts seem incorrect for the brands I have tested. It would be better if the tool showed opportunity prompts, keywords, or questions based on AI search volume and competition (easy or difficult to rank for). Ahrefs and other AI tools already provide this.
- The suggested tasks are often irrelevant to the domain, for example, suggesting adding a Google My Business profile when the domain has no location and is not a location-based business.
- There is no way to simply click and see a full list of sites citing your domain or to investigate competitor site citations.

Overall, the tool is okay, but the cons outweigh the pros for me personally. I am giving it a ⭐⭐⭐ rating. Hopefully, they can improve the points I have mentioned, so the tool will be better positioned to compete with similar tools in the market. Right now, it is not at the level of other competing tools.
