Frequently Asked Questions

SureThing.io FAQ

How is SureThing different from a chatbot like ChatGPT?

Chatbots are reactive tools that require constant prompting and instruction, losing context after each session. SureThing is a proactive, autonomous agent with persistent memory.

How does SureThing learn my preferences and "voice"?

Through continuous interaction and observation of your work. As you work and provide feedback on its actions (like edited email drafts or corrected calendar entries), its state-of-the-art memory system builds a nuanced model of your communication style, priorities, and decision-making patterns. This learning process accelerates over time, requiring less manual input.

Can I control what actions SureThing takes autonomously?

Absolutely. You define the scope and permissions. SureThing can be configured to only draft emails for your review, or it can be authorized to send certain types of routine communications automatically. For significant actions like scheduling high-stakes meetings, it will typically seek confirmation. You maintain full oversight and control over its level of autonomy.
