Personally I have built every bot from scratch. This isn’t because the bot templates are not useful, but because exploring the conversation flows and logic behind the flows helped me grasp what ways I wanted to use the bots. Now, templates will be great for everyone, but I think they should be rated by users with reviews, have more than one option depending on specific features, and have some attached data (like analytics) on who the bot is most effective on (and maybe some tips and or tricks on how to target different audiences). I’m thinking like themes for websites that you can download, but for bots.
I would suggest building feature centric bot templates (like a bot that runs an API that will drastically help an business in an industry provide something for users then build out some basic intro and exit branches that say “enter your business slogan here”, “[your business name]”, etc. throughout the bot, so users can literally follow step-by-step instructions.
As TARS grows, I would suggest allowing independent bot builders a avenue to build bot templates that cost a little extra money (depending on their usefulness/complexity) that users can purchase for say $5 to use as their template like website themes. This would create a competitive space that drives your bot templates, bot solutions, and creates incentives for developers to contribute their templates to your services.
