+# ReAct: question answering with Reasoning and Actions
+
+## What is ReAct?
+
+[ReAct](https://arxiv.org/abs/2210.03629) (Reason+Act) is a classis AI question-answering feature,
+that combines reasoning with actions to provide informed answers.
+
+Within Big-AGI, users can invoke ReAct to ask complex questions that require multiple steps to answer.
+
+| Mode  | Activation                        | Information Sources                                  | Reasoning Visibility               | When to Use                                      |
+|-------|-----------------------------------|------------------------------------------------------|------------------------------------|--------------------------------------------------|
+| Chat  | Just type and send                | **Pre-trained knowledge only**                       | Only shows final response          | Quick answers, general knowledge queries         |
+| ReAct | Type "/react" before the question | **Web loads, Web searches, Wikipedia, calculations** | Shows step-by-step thought process | Complex, multi-step, or research-based questions |
+
+Example of ReAct in action, taking a question about current events, googling results, opening a page, and summarizing the information:
+
+https://github.com/user-attachments/assets/c3480428-9ab8-4257-a869-2541bf44a062
+
+The following tools are implemented in Big-AGI:
+
+- **browse**: loads web pages (URLs) and extracts information, using a correctly configured `Tools > Browsing` API
+- **search**: searches the web to produce page URLs, using a correctly configured `Tools > Google Search` ([Google Programmable Search Engine](https://programmablesearchengine.google.com/about/)) API
+- **wikipedia**: looks up information on Wikipedia pages
+- **calculate**: performs mathematical calculations by executing typescript code
+  - warning: (!) unsafe and dangerous, do not use for untrusted code/LLMs
+
+## How to Use ReAct in Big-AGI
+
+1. **Invoking ReAct**: Type "/react" followed by your question in the chat.
+2. **What to Expect**:
+
+- An ephemeral space will show the AI's thought process and actions, showing all the steps taken.
+- The final answer will appear in the main chat.
+
+3. **Available Actions**: Web searches, Wikipedia lookups, calculations, and optionally web browsing.
+
+## Good to know:
+
+- **ReAct operates in isolation** from the main chat history.
+- It **will take longer than standard responses** due to multiple steps.
+- Web searches and browsing may have privacy implications, and require **tool configuration** in the UI.
+- Errors or limitations in accessing external resources may affect results.
+- ReAct does not use the [Tool or Function Calling](https://platform.openai.com/docs/guides/function-calling) feature of AI models, rather uses the old school approach of parsing and executing actions.
