One workspace. Multiple models. Focused agents for different tasks. 3S AI is an AI workspace built around agent collaboration, information understanding, and event foresight. Whether you need to organize material, compare options, break down a goal, improve your writing, explore ideas, understand a concept, or examine a developing public event, you can choose the right agent and start a conversation. You do not need to master complex prompts first. Tell the agent what you want to achieve, share any material you already have, or explain where you are stuck. It can ask follow-up questions, organize the task, and help move it forward. When you want a different approach, you can also switch AI models within the conversation. Key Features: 1. Focused Agents for Different Tasks Choose an agent that fits the task. Start with a simple request or paste in existing material. Each agent has its own capabilities, interaction style, and task focus, with support across scenarios such as: • Understand information: Map event context and key changes, or pull the main points from long documents, notes, and meeting records. • Compare options: Examine benefits, trade-offs, constraints, and possible risks to clarify the basis for your decision. • Plan next steps: Turn broad goals into practical steps, set priorities, and identify what to do next. • Improve communication: Preserve your meaning and voice while refining wording, structure, and tone. • Develop ideas: Explore new angles, generate directions, and shape rough thoughts into ideas you can build on. • Learn and prompt better: Explain concepts clearly and turn rough needs into specific, actionable AI prompts. 2. Leading AI Models in One Space Use multiple AI models in one workspace and switch between them to fit the task. Conversations continue from the current context, reducing repeated explanations and unnecessary restarts. 3. Natural Conversations That Keep Moving Whether the task is quick or complex, begin with the right agent. It can ask, organize, and refine as the conversation develops, helping turn rough thoughts into clearer answers, plans, or messages. 4. More AI Features, Including Event Foresight Alongside focused agents, 3S AI also includes public-event foresight and the Judgment Academy. Explore editor-curated topics, event context, and public sources. Make your own YES or NO judgment before viewing the community distribution and record your reasoning. After submitting, compare perspectives and use 3S AI to organize supporting evidence, counterarguments, key variables, and conditions that could change the outlook. You can also study probability, base rates, evidence analysis, trend recognition, and uncertainty through structured lessons and practice. 5. Review Conversations and Progress Revisit past conversations, event judgments, and course progress, then continue unfinished tasks without starting from the beginning. 6. Control How Your Data Is Used You can choose whether processed event selections and conversation feedback may be used to improve 3S AI. Turning this permission off does not limit agent use, event participation, 3S AI analysis, or other core experiences. Important Disclaimer: 1. Agent responses and event analysis in 3S AI are generated from public sources, event context, or content you provide. They may be incomplete, biased, or inaccurate and are not a guarantee of facts or future outcomes. 2. 3S AI provides general assistance with information organization, writing, creativity, learning, planning, independent judgment, perspective comparison, and event analysis. It does not provide financial, securities, investment, gambling, legal, medical, or other professional advice, and it does not offer political campaigning or targeted persuasion.
