Montage — The runtime for agentic user interfaces
Montage
A model-agnostic SDK that renders agentic, interactive UIs, hydrates artifacts faster, and reduces token usage across underlying models.
Key features
- Model-agnostic SDK: A single SDK and runtime that works with any underlying model provider, enabling developers to render agentic UI components without locking into a specific LLM.
- Agentic UI Rendering: Renders rich, interactive components (agentic widgets) that encapsulate agent behavior, state, and UI in a reusable format for web applications.
- Faster Hydration: Optimized client/server hydration flow to initialize interactive artifacts quickly, reducing perceived latency for end users.
- Token Usage Reduction: Built-in optimizations for prompt/state management that cut token usage across models, lowering operational costs and improving efficiency.
- Stateful Artifact Management: Manages and persists the state and lifecycle of interactive artifacts and their events, simplifying developer handling of agent-driven UI.
- Seamless Front-end Integration: Designed to integrate with common front-end workflows and frameworks, allowing easy embedding of agentic interfaces into existing apps.
- Model Swapping and Fallbacks: Enables switching or combining different underlying models without reauthoring UI logic, supporting fallbacks and provider-agnostic strategies.
- Developer Tooling: Provides developer-oriented APIs and runtime controls to debug, test, and tune agentic components and their interactions.
- Single SDK to render rich, interactive agentic UI components
- Runtime that hydrates interactive artifacts faster
- Reduces token usage across underlying models
- Model-agnostic operation that works with any underlying model
- Focus on rendering agentic interfaces and interactive components
Best for
- Embedding conversational, agent-driven widgets in web apps to handle complex, interactive user workflows without rebuilding front-end UI each time.
- Prototyping agentic interfaces quickly using the single SDK to iterate on UI/agent behavior while swapping underlying models for evaluation.
- Reducing LLM operational costs by leveraging Montage’s prompt and state optimizations to cut token usage across responses and background context.
- Hydrating server-rendered interactive artifacts on the client for faster startup and seamless handoff from server logic to agent-driven interactions.
- Integrating multiple model providers and failover strategies so applications can route requests to different models without changing UI code.
- Managing long-lived, stateful agent interactions (e.g., multi-step assistants or tool-using agents) with built-in lifecycle and state management.
- Build interactive agentic user interfaces with a single SDK
- Embed agent-driven UI components into applications while minimizing token costs
- Hydrate and rehydrate interactive artifacts quickly for responsive UX
- Integrate agentic UI rendering on top of different underlying language models
UseIt Studio
USEIT PTE. LTD.
AI design studio that turns ideas into editable, print-ready designs for cards, packaging, stickers and more.
Key features
- Conversational Editing: Select part of an artwork and describe a change; the rest stays untouched.
- Editable Layers: Separates designs into layers so text, graphics and vectors can be fine-tuned.
- Matching Sets: Expands one artwork into cards or sets while keeping style and palette.
- 2D to 3D Preview: Edit the flat design and watch a live 3D preview update.
- Craft and Cut Lines: Traces cut lines and adds white ink plates for acrylic and stickers.
- Illustrator Handoff: Open the same file in Illustrator and keep editing by conversation.
- Gallery: Publish designs others can remix with their own content.
Best for
- Custom Packaging: Designing gift boxes and packaging with correct dielines.
- Stickers and Pins: Turning a sketch into production-ready stickers or pins.
- Brand Kits: Carrying one visual identity across cups, bags and menus.
- Personal Gifts: Making cards, invitations and keepsakes.
- Acrylic Standees: Generating cut lines and white ink layers for print shops.
