When evaluating conversation design tools, I examine five key areas: ease of use, collaboration, integrations/export options, design fidelity, and prototyping. Each tool has its strengths and weaknesses in these categories, and there is no one perfect tool for every designer or team. Products change rapidly over time, so it's essential to try out multiple tools to find the best fit for your specific use case. The "feel" of a tool can also vary depending on individual comfort levels, but this will ultimately depend on personal preference. By understanding each tool's capabilities and limitations, you can make an informed decision about which one suits your needs.
