DiagramMatic is an AI assistant developed by Mauricio Perera, designed to transform textual descriptions of flows into Mermaid diagrams in a user's chosen language. The tool helps analyse and organize information from the textual input. If necessary, the assistant interacts with the user, asking clarifying questions to ensure accurate diagram generation. Once the flow is understood, Mermaid diagrams are created, thereby translating the text-based flow descriptions into a visual format that can be easier to comprehend or present. If required, there is also an option to translate the diagram into another language. This multi-language support enhances the tool's usability by a broader audience. The prime application of DiagramMatic is in fields where flow diagrams are extensively used, such as in process analysis, software design or project management. Users will need to sign up or log in to use the tool.
