The UI for AI

Build interfaces
humans + AI can reason about.

Beverly is a small, native UI runtime built for AI-native applications — fast for humans, understandable by agents, and safe by default.

The Bigger Idea

AI can generate code faster than humans ever could. The bottleneck is the substrate.

AI-native applications need interfaces for conversations, tools, workflows, approvals, data, files, realtime events, and continuously changing state. The UI is no longer decoration — it is infrastructure.

Beverly provides a reliable, composable substrate for building it.

01 / SMALL

A runtime you can actually ship.

A small native runtime with fast startup, low overhead, local execution, and no browser required. Beverly is designed to live inside the product — from desktop applications to embedded devices.

SMALL
02 / AGENT-FRIENDLY

Built for humans. Understandable by agents.

Predictable APIs, strongly typed primitives, explicit state, deterministic layouts, and semantic components give both people and AI a vocabulary for building interfaces. If an agent can understand the primitives, it can build the interface.

HUMAN + AI
03 / SAFE

AI generates. Rust verifies.

Rust's ownership, type system, exhaustive matching, and compile- time guarantees constrain entire classes of mistakes before the application ships. Probabilistic generation gets a predictable systems substrate.

RUST
04 / LOCAL

Your AI's interface can live next to your AI.

Run next to your models, files, databases, microphones, cameras, sensors, GPUs, and private data. No mandatory cloud UI layer and no requirement that every interaction cross a network boundary.

LOCAL
The Primitive Layer

Small primitives. Huge surface area.

Beverly does not need hundreds of abstractions. A small set of composable, strongly typed primitives can become the foundation for complex AI interfaces — from conversations and dashboards to tools, workflows, inspectors, and realtime systems.

Virtualized Data Views Large datasets without turning the UI into a bottleneck.
Command Surfaces Actions that humans can invoke directly and agents can address programmatically.
Agent Tool Cards Structured rendering for tool calls, results, states, approvals, and autonomous work.
Telemetry Interfaces Live system state, events, logs, and realtime operational views.
Data Grids & Trees Structured information primitives that remain composable as complexity grows.
Streaming States Loading, partial, live, stale, error, and updating states as native primitives.
Glass & Surface System GPU-native depth, blur, gradients, glass, borders, and adaptive themes.
Interaction Feedback Focus, hover, selection, validation, transitions, animation, and state changes.
Human + Agent Controls One semantic interaction model for people, automation, and AI agents.
Local by Default

The UI belongs with the application. Not behind a browser boundary.

AI applications increasingly need direct access to models, files, databases, devices, sensors, GPUs, and private data. Beverly treats local execution as a first-class assumption, so the interface can run where the intelligence and data already live.

No Browser Required Ship a native interface without turning your application into a web application first.
Private by Design Keep models, data, files, and interactions on the machine or network where they belong.
GPU-Native Shaders, animation, glass, effects, and realtime visualization are first-class capabilities.

Keep Your Intellectual Property In-House

Your domain expertise and institutional knowledge are your most valuable assets. Cloud AI APIs risk handing those hard-won insights over to future competitors who can reverse engineer your products and services. Beverly Agent brings AI compute to the machines you already own. Run open-source models locally for free, and protect your most sensitive information.
