Thanks for noticing this Tyler, we really liked the idea of getting back to lifetime one-time purchases. Alice is a desktop app and it doesn’t use our cloud resources much, so this should be also feasible for the long run. Please, give Alice a try, you won’t regret it!

BotDojo is one of the most powerful AI Agent builders I've found out there. As a non-technical marketer, it took me a minute to get familiar with the designer, but using the preexisting templates is super helpful! I am now running outreach 100% on autopilot. BotDojo personalizes the copy for each contact we reach out to by email and LI. It also takes care of the drip campaign that I run through Lemilist. LOVE IT! I really hope to see more templates coming up soon!

MD Shahab, thank you for reporting the bug. That shouldn't have happened, and I'll investigate the issue. If it fails again, please try re-running the same query - this isn't a common occurrence. Since it's an agent-based system, it may take some time to combine responses from all sources.
