How many buttons does your codebase have? Not designs, actual button implementations. Two? Five? Does anyone know which one is the real one?
Interface components multiply because writing a new one is always faster than finding the existing one. The AI Component Generator makes the first version cheap and complete, with props, states and keyboard behaviour included, so the one you write is worth keeping.
Short answer: The AI Component Generator is a free AIToolsay tool that writes user interface components from a description. Set the language, the code style and the comment level, and choose whether to include error handling, usage examples and tests alongside the component.
What is AI Component Generator?
A component is a reusable piece of interface with a defined input surface: props or attributes going in, events coming out, and a set of visual states in between.
The prompt box asks you to describe what the component generator should produce, with requirements, inputs and expected behaviour. For components that means the props, the states and the events. Everything else follows from those three lists.
Language covers Auto Detect plus Python, JavaScript, TypeScript, Java, C#, C++, Go, PHP and Ruby, which in practice means you set TypeScript or JavaScript for most frontend work and name the framework in Custom Instructions.
Why Use AI Component Generator?
Components are rarely hard and almost always incomplete. The happy state gets built and the rest arrive as bug reports: loading, empty, error, disabled, too much text, no text at all.
Describing the states up front means they are in the first version. That is the difference between a component you extend and one somebody quietly replaces six weeks later.
| State | When it usually gets built | What it costs to add late |
|---|---|---|
| Loading | After the first slow connection | A prop added to every call site |
| Empty | After a demo with no data | Layout rework |
| Error | After the first failed request | New styling and new copy |
| Disabled | When a form needs it | Usually a rewrite of the event handling |
Who Should Use It?
- Frontend developers starting a component library and wanting a consistent first version
- Full stack developers who write interface code occasionally and want the accessible version by default
- Designers who code and know exactly what the states should be
- Teams migrating frameworks who need the same component expressed twice
- Anyone prototyping where a complete component is faster than a placeholder
Note Name your framework and styling approach in Custom Instructions. React with Tailwind, Vue with scoped CSS and Svelte with CSS modules produce very different files, and the Language dropdown alone cannot tell them apart.
How Does AI Component Generator Work?
Prompt box. Describe the component: its props with types, its visual states and the events it emits.
Model selector. Set the engine first, from MSB AI, OpenAI ChatGPT, Google Gemini, Anthropic Claude AI, xAI Grok AI, DeepSeek, Qwen, Meta AI, NVIDIA AI, OpenRouter AI and MiniMax.
Advanced options accordion. Ten controls: Language, Code Style, Comment Level and Output as dropdowns, four toggles, a Detail Level slider and a free text instruction field.
Generate button. Description, model and settings pass through the prompt engineering layer written for code generation, which is the instruction set that returns a component file rather than a discussion of component design.
Output card. The component appears under the button with a live word count, alongside copy, listen, reuse, download and open in full view.
Export row. DOC, TXT and HTML. TXT preserves the indentation, which matters for markup heavy files.
Activity history. Session generations stay listed under the result, so a whole set of components generated in one sitting stays available while you check them against each other.
Step-by-Step Guide
- Write the props as a list with types and defaults.
- List every visual state, including empty, loading, error and disabled.
- List the events the component emits and what each one carries.
- Open the AI Component Generator and paste all three lists in.
- Put your framework, styling approach and accessibility requirements into Custom Instructions.
- Set Output to Code + Usage Example so you can see how the component is called.
- Generate, then check the states first. Missing states are the most common gap.
- Test it with keyboard only before you accept it.
Key Features
Props with types
The input surface is defined properly, with defaults, rather than growing one optional prop at a time.
Every state built
Loading, empty, error and disabled arrive with the first version instead of being retrofitted later.
Keyboard and labels
Ask for accessibility in Custom Instructions and roles, labels and focus handling come with the component.
Usage example included
Seeing the component called is the fastest way to notice a prop that should not exist.
Advanced Options Guide
| Option | What it controls | When to change it | Suggested start |
|---|---|---|---|
| Language | Auto Detect, Python, JavaScript, TypeScript, Java, C#, C++, Go, PHP or Ruby | Set it, then name the framework separately in Custom Instructions | TypeScript for most component work |
| Code Style | Clean / Idiomatic, Beginner Friendly, Production Ready, Minimal, Verbose, Functional, Object Oriented or Performance Optimized | Functional for hooks based components, Minimal for a quick prototype | Clean / Idiomatic |
| Comment Level | No Comments, Light Comments, Well Commented or Fully Documented | Fully Documented for a shared component library | Light Comments |
| Output | Code Only, Code + Explanation, Code + Tests, Code + Usage Example or Step by Step | Code + Tests when the component has real interaction logic | Code + Usage Example |
| Add Comments | Adds inline notes in the markup and handlers | Turn off for simple presentational components | Off |
| Include Error Handling | Adds the error state and guards around bad props | Leave on for anything that displays fetched data | On |
| Include Example Usage | Shows the component rendered with props | Keep on. An awkward call site shows up immediately | On |
| Generate Tests | Adds tests for rendering and interaction | Turn on for anything with events or conditional rendering | On |
| Detail Level | Slider from 1 to 100 controlling how many states and edge cases appear | Raise it when you want every state and full keyboard support | 65 |
| Custom Instructions | Free text up to 1000 characters over the settings | The most important field here. Framework, styling and accessibility go in it | "React 18 function component, Tailwind classes, forward the ref, WCAG AA" |
Caution Accessibility is only included if you ask for it. Roles, labels, focus order and keyboard handling should be in Custom Instructions on every generation, not added after someone reports that the modal cannot be closed with a key.
Example Inputs
Component: DataTable row actions menu.
Props
actions list of {id, label, danger?: boolean}
disabled boolean, default false
align "left" | "right", default "right"
States
closed, open, disabled, empty actions list (render nothing)
Events
select(actionId)
open, close
Behaviour
Closes on outside click and on the escape key
Arrow keys move between items, enter selects
Danger actions appear last and are visually distinct
The behaviour block is what turns this from a dropdown into a usable menu. Escape handling and arrow key movement are the two things hand written menus almost never have.
Example Outputs
With Custom Instructions naming React, Tailwind and WCAG AA, the component comes back with the props typed, the four states rendered and a keyboard handler wired to the list.
const onKeyDown = (e: KeyboardEvent) => {
if (e.key === "Escape") return close();
if (e.key === "ArrowDown") return moveFocus(1);
if (e.key === "ArrowUp") return moveFocus(-1);
if (e.key === "Enter") return select(focusedId);
};
The empty actions case is the one worth checking. The description said render nothing, and a component that renders an empty bordered box instead is technically working and visually wrong. That is the kind of thing to verify rather than assume.
For the styling layer specifically, the AI CSS Generator handles it in more depth, and interaction logic that outgrows the component belongs in the AI JavaScript Generator.
Tips & Common Mistakes
What produces a component worth keeping
- Props, states and events written as three separate lists
- Framework and styling named in Custom Instructions
- Accessibility asked for explicitly, every time
- The usage example read as if you were another developer
What produces one you will replace
- Describing appearance instead of behaviour
- Forgetting the empty and error states
- Letting a component take fifteen props because they were all mentioned
- Accepting it without a keyboard only test
- ✅ Props listed with types and defaults
- ✅ Every visual state named
- ✅ Events listed with their payloads
- ✅ Framework and styling in Custom Instructions
- ✅ Component tested with the keyboard before acceptance
| Component kind | Detail Level | Generate Tests |
|---|---|---|
| Presentational, no events | 40 | Off |
| Form field with validation | 65 | On |
| Menu, dialog or anything with focus | 80 | On |
| Prototype for a demo | 30 | Off |
Pro tip Generate the component once with Detail Level at 40 and once at 80, then diff them. Everything the higher version added is a state or an interaction you had not thought about, and you get to choose which of those you actually want rather than discovering them in a bug report.
AIToolsay is a free AI tools platform made of dedicated workspaces rather than a single chat box with different names on it. Each tool carries its own prompt engineering and its own options panel, which is why this one asks about code style and comments instead of tone and length. Every tool is free, with no account required before you start. You decide which engine answers, choosing from MSB AI, OpenAI ChatGPT, Google Gemini, Anthropic Claude AI, xAI Grok AI, DeepSeek, Qwen, Meta AI, NVIDIA AI, OpenRouter AI and MiniMax, and component conventions move quickly enough that comparing two engines is often worth the extra minute. Around the tools sit an AI directory, an AI models directory, courses, prompts, guides and news. The full library is one click away on the AIToolsay homepage.
Frequently Asked Questions
Is the AI Component Generator free?
Yes. It is free to use, nothing is installed, and no account is needed to generate a component.
Which frameworks can it target?
Set Language to TypeScript or JavaScript and name the framework in Custom Instructions. React, Vue, Svelte, Angular and plain web components all work when you say which one you want.
Will the component be accessible?
Only if you ask. Put your accessibility requirement in Custom Instructions and it arrives with roles, labels and keyboard handling. Always test it with the keyboard yourself before accepting it.
Does it generate the styles too?
It writes whatever your styling approach implies, such as utility classes or a scoped block. For anything more involved, generate the component here and take the styling to a dedicated CSS tool.
How do I stop the prop list growing?
List the props you want and nothing else. If the generated component has props you did not ask for, that is usually a sign the description mixed appearance with behaviour.
Can it produce the same component for two frameworks?
Yes. Generate once, change the framework in Custom Instructions, generate again. Both versions stay in the activity history so you can check the interfaces match.
Should I generate tests for components?
For anything with events or conditional rendering, yes. Purely presentational components rarely need them, and Generate Tests is a toggle so you can decide per component.
Every component you build is a small promise about how the interface behaves. Write the props, the states and the events down before you generate anything, ask for accessibility every time, and let the AI Component Generator produce a first version complete enough that nobody needs to write a second one.
