Most .NET AI integrations stop at inference. LM-Kit.NET covers the full range of capabilities production applications actually need: agentic workflows with tool calling, planning, and memory; document intelligence with OCR and structured extraction; retrieval-augmented generation with built-in vector storage; multilingual speech-to-text; vision and multimodal understanding; text analysis with classification, NER, PII extraction, and sentiment; and text generation with translation, summarization, and constrained output. Ships in one NuGet package, runs in-process with no sidecar services, and works across all major hardware acceleration backends. Drop-in replacement for Semantic Kernel through its Microsoft.Extensions.AI compatibility layer. 29 Ratings Visit Website SurveyJS SurveyJS is an embeddable, self-hosted, white-label form builder for teams building custom forms, surveys, questionnaires, and other data collection tools inside web applications. It runs entirely on the client and is fully compatible with all modern JavaScript frameworks, including React, Angular, and Vue. SurveyJS integrates with any backend, giving you full control over data, security, user access, deployment, and business logic.

About OpenUI is an open-source (MIT) generative UI framework for AI agents. Instead of plain text, your agent writes OpenUI Lang, a compact, streaming-first language, and OpenUI renders it progressively as real UI: charts, tables, forms, cards and layouts. Rendering is safe by default: the model can only use components you register and no generated code is executed, so your design system stays in control. A framework-agnostic core powers first-party runtimes for React, Vue, Svelte and Angular, with ready-made chat interfaces and integrations for LangChain/LangGraph, the Vercel AI SDK, Mastra, Google ADK, assistant-ui, CopilotKit, AG-UI and A2UI. In its published benchmark, OpenUI Lang uses about half the tokens of equivalent JSON UI formats, so interfaces stream faster and cost less.	About Superinterface is an open source platform that enables seamless integration of AI-driven user interfaces into your products. It offers adaptable, headless UI options, allowing you to add in-app AI assistants with interactive components, API function calls, and voice chat capabilities. The platform supports various AI models, including those from OpenAI, Anthropic, and Mistral, providing flexibility in AI integration. Superinterface simplifies the process of embedding AI assistants into your website or application through methods like script tags, React components, or dedicated webpages, ensuring quick setup and compatibility with your existing technology stack. Customization features allow you to tailor the assistant's appearance to match your brand, including avatar selection, accent colors, and themes. Additionally, it supports functionalities such as file search, vector stores, and knowledge bases, enhancing the assistant's ability to provide relevant information.
