PatternBase is a code-copying resource for React developers building AI interfaces: it presents 54 reusable interaction patterns, with implementations for Ant Design, Mantine, and shadcn/ui. Rather than installing it as a conventional npm package, you choose a pattern and framework, then copy and adapt the code in your project.
What PatternBase provides
PatternBase presents a collection of AI-interface patterns intended to help developers implement interactions such as prompt suggestions, citations, response streaming, model selection, attachments, and memory controls. Its stated collection contains 54 patterns, grouped into five categories. The count and scope come from the project’s announcement, not an independent evaluation.

The announcement describes implementations for Ant Design, Mantine, and shadcn/ui, organized around a shared TypeScript API. These are alternative framework implementations of interface patterns, not a claim that every product needs every interaction.
How the patterns are organized
The five categories group patterns by the kind of interaction they support:
#1 Best Overall
- Prompt Actions: actions applied to prompts or generated content, such as Regenerate and Transform.
- Wayfinders: help users get started or find a direction, including Suggestions and Templates.
- Tuners: controls for configuring AI behavior, including ModelManagement and Attachments.
- Governors: controls that shape or constrain use, including examples such as consent and incognito mode.
- Trust Builders: interactions that help users understand or assess AI output, including Citation, Verification, and Memory.
These are the categories and examples described in the announcement; the examples are not requirements for every AI product.
How to use PatternBase in a React project
- Open the PatternBase documentation and live-preview site: pattern-base.netlify.app.
- Find a pattern that fits the interaction you want to implement.
- Choose the implementation for Ant Design, Mantine, or shadcn/ui.
- Open the pattern’s code, copy it, and adapt it in your project.
- Check whether the copied component relies on shared types, hooks, or utilities. The announcement says these shared pieces are held in
@patternbase/core, so account for that dependency when integrating the code.
The key practical distinction is the acquisition model: the described workflow is to copy code into your own project, not to add PatternBase as a conventional dependency in package.json. Expect to inspect and maintain the code you adopt alongside your application.

Choosing a framework and a pattern
Choose based on your existing React stack and the user need you are addressing. The project announcement supplies three framework options, but it does not provide an independent comparison of their quality or suitability.
- Framework implementation: pick the option that matches the component system already used by your project.
- Interaction need: decide whether you need help with discovery, behavior controls, visibility, or transparency before selecting a pattern.
- Code ownership: use the copy-and-adapt workflow if you want the implementation in your codebase; it differs from relying on a traditional installed component package.
What is and is not established
The project description and workflow here are reported by Kelvin Kiptum Kiprop’s DEV Community announcement, “PatternBase: 54 AI UX Patterns for React Developers”. It identifies the source repository as github.com/design-sparx/pattern-base and names shapeof.ai as the taxonomy source. Those destinations and claims are reported in the announcement; their current availability and details are not independently established here.
The announcement also described PatternBase as early-stage, with one contributor, and MIT licensed. Those are historical claims from that article, not confirmation of the project’s current contributor count, license, repository activity, or status. Check the repository for current information before relying on them.
