SureThing.io FAQ
How does SureThing's "memory" actually work?
SureThing employs a state-of-the-art agentic memory system that creates a persistent, evolving profile of you. It doesn't just remember facts from a single chat; it learns your goals, communication style, preferences, and patterns across all interactions and over extended time. This memory is accessed and reinforced cyclically with each task, allowing the agent to make better, more context-aware decisions continuously, without you having to re-explain yourself.
Is my data secure with SureThing?
Absolutely. Security and reliability are foundational to SureThing. It is SOC 2 Type II certified, which is an rigorous audit of our security controls, and is Google CASA Tier 2 compliant. Your data is handled with enterprise-grade protections, ensuring confidentiality, integrity, and availability. We are built for real work with real security, not just demos.
What makes SureThing different from a chatbot like ChatGPT?
Traditional AI chatbots are reactive—they wait for your prompt and provide a single response. SureThing is a proactive, autonomous agent. It takes initiative, works across your connected apps 24/7, and executes multi-step tasks on your behalf. Crucially, its persistent memory allows for a continuous, evolving partnership, whereas chatbots treat each conversation as isolated, lacking long-term context and the ability to learn iteratively from past interactions.
Can I control what actions SureThing takes?
Yes, you maintain full oversight. SureThing is designed for autonomous assistance, not replacement. For significant actions like sending a final email or booking a meeting, it will typically seek your approval or present a draft for your review. You can set boundaries and preferences, and the agent learns from your feedback cyclically, continuously refining its autonomy within the guardrails you establish.
