Seedance 2
Seedance 2 generates stunning 2K videos with multi-shot storytelling, native audio, and consistent characters.
Feature Comparison
OnUml
AI Smart Chat
This is the star feature of OnUml. Instead of memorizing complex Mermaid syntax, you can describe your diagram needs in natural language. For example, you can type "Create a sequence diagram for a user login process with a database check" and the AI will generate the corresponding, syntactically correct Mermaid code for you. It acts as your intelligent design partner, translating your ideas into a structured diagram format instantly, which is perfect for brainstorming or quick documentation.
Live Diagram Rendering & Preview
As you type in the Mermaid editor or receive code from the AI chat, a live preview pane updates in real-time. This WYSIWYG (What You See Is What You Get) experience allows for immediate feedback. You can see exactly how your diagram will look as you build it, making it incredibly easy to spot errors, adjust layouts, and iterate on your design without any frustrating back-and-forth between coding and viewing.
Built-in Mermaid Editor with Smart Hints
For users who prefer direct control or want to fine-tune the AI's output, OnUml provides a clean, minimalist code editor dedicated to Mermaid syntax. It includes smart code hints and automatic syntax fixes to help you write valid code faster. This feature is ideal for learning Mermaid or for making precise adjustments to complex diagrams that require a developer's touch.
Diagram Export and Organization
Once your diagram is perfect, OnUml lets you export it in high-quality formats like PNG and SVG, making it simple to share in documentation, presentations, or reports. The platform also emphasizes ease of use with code saving and organization features, allowing you to keep your projects tidy and accessible for future edits, all without requiring any user registration.
Seedance 2
Multi-Shot Storytelling
Seedance 2 introduces the innovative feature of multi-shot video generation, enabling users to create narratives that flow smoothly from one scene to another. This allows for the development of complex stories without the need for manual editing, giving creators a streamlined workflow.
Native Audio Generation
One of the standout features of Seedance 2 is its ability to generate native audio alongside visuals. This means that all sound elements, including dialogue, sound effects, and ambient sounds, are created in sync with the video, delivering an immersive cinematic experience.
Character Consistency
Seedance 2 ensures that characters maintain a consistent appearance throughout all scenes. By utilizing reference images, the AI guarantees that character designs remain cohesive, making it an ideal tool for storytelling and brand consistency in marketing materials.
Multimodal References
With Seedance 2, users can upload up to 12 multimodal references, allowing for precise motion replication. This feature enhances the realism of the generated videos and enables creators to achieve the specific movements and styles they envision for their projects.
Use Cases
OnUml
Software Architecture Documentation
Developers and architects can quickly draft and iterate on system design diagrams, such as class diagrams, component diagrams, or deployment diagrams. By describing the system components and their relationships to the AI, they can generate visual documentation that is essential for team alignment and technical specs, speeding up the design phase significantly.
Creating Technical Tutorials and Guides
Technical writers and educators can use OnUml to effortlessly generate flowcharts and sequence diagrams to embed in tutorials, blog posts, or course materials. The AI chat simplifies the process of creating clear, visual explanations of complex processes, making technical content more engaging and easier for readers to understand.
Planning and Visualizing Workflows
Project managers and analysts can map out business processes, user journeys, or algorithm flows. By conversing with the AI to create activity diagrams or flowcharts, they can visualize steps, decision points, and outcomes, which is invaluable for process optimization, onboarding, and team discussions.
Rapid Prototyping and Brainstorming
During planning meetings or brainstorming sessions, teams can use OnUml in real-time to visualize ideas. Instead of sketching on a whiteboard, they can type a prompt like "show a user signing up, verifying email, and accessing a dashboard" and immediately get a shareable, professional diagram to center the discussion and capture decisions.
Seedance 2
