Overview
The Inline AI Assist control delivers contextual AI help directly inside editors, input fields, and UI elements, so users can access it while staying in their workflow. It’s ideal for compact tasks like polishing wording, creating summaries, clarifying content, translating, correcting grammar, generating code, and similar work.

Inline assistance
The control surfaces at the user’s point of interaction—beside a text selection or UI element—using auto-positioning and collision detection to remain visible. This reduces context-switching and accelerates AI-assisted workflows in editors, forms, grid cells, and code inputs.


Pop-up mode for extended responses
When a reply requires more space, the control can open in pop-up mode. This gives you a larger dialog that comfortably displays multiparagraph answers and lengthy code examples.
Customizable commands
Developers can define custom AI commands that leverage selected text and editor context to craft intelligent prompts. These commands are configurable for domain-specific needs such as text refinement, code creation, summarization, and translation.


Response actions
Default response controls let users accept or dismiss suggestions, and the control supports adding custom actions. Teams can implement domain-specific behaviors, like insert, copy, or feedback hooks, to fit their application workflows.
Streaming response
Render responses as a live stream with incremental updates and progress indicators for a conversational experience. Developers control streaming behavior, including abort and cancel options, to keep the UI responsive and lower perceived wait times.


Adaptive AI Assist toolbar
A responsive toolbar can appear beside the editor in inline mode or dock below it in bottom mode.
Fully customizable with templates
Every aspect of the control can be templated, from the input editor and command list to the theme and styling. Template-driven customization makes it easy to tailor the UI for specific domains while keeping visual consistency.

Works with any AI service
The control is back-end-agnostic, giving developers control over prompt handling, streaming, and error flows. It supports OpenAI, Google Gemini, Anthropic Claude, Azure OpenAI, and in-house models, avoiding vendor lock-in and enabling cost-optimization via custom response injection.
Accessibility
- Full keyboard support, including Tab/Shift+Tab, arrow-key navigation, and screen-reader updates during response streaming.
- Meets WCAG 2.2 AA standards with high-contrast modes, correct ARIA labeling, and robust focus management.
Built-in themes
The ASP.NET MVC Inline AI Assist includes built-in themes: Tailwind CSS, Bootstrap 5, Bootstrap 4, Bootstrap, Material, Fabric, Fluent, and high contrast. Developers can customize these themes or create new ones by overriding SASS variables or using the Theme Studio application.
