Developers only. Limited spots.

The Problem

AI transformed engineering.

While developers use Claude Code to ship 10x faster, the rest of the company is still copy-pasting between legacy UIs.

The Insight

Don't bypass the user.

The user's session is the ultimate capability boundary. Why build new auth when the agent can simply inherit the existing one?

The Solution

One slash command.

Run /char:setup in Claude Code. The AI analyzes your app, writes the tools, tests them, and styles the agent to match.

$ /char:setup

Agent embedded
Tools written and tested
Styled to match your app
The Moat

TDD for AI.

The agent builds and verifies its own integration. If it works for Claude in development, it works for your users in production.

Localhost
Production

Standards-First.

Built on MCP (Model Context Protocol) and WebMCP. No lock-in. Switch models, switch hosts, keep your tools.

MCP Foundation
WebMCP API
Char Embed

Works Everywhere.

From React and Next.js to legacy jQuery and plain HTML. If it runs in a browser, Char works.

React
Vue
Svelte
WebMCP

Deterministic tools in the browser

WebMCP is "MCP-style tool calling in the browser": tools are real functions, invoked as parse → validate → call (no eval).

1
Embed Char Drop in the runtime (UI optional)
2
Expose tools Your frontend registers deterministic functions
3
Connect MCP servers Remote OAuth-backed servers (optional)
What you get Tabs publish tools to the hub, any MCP client can connect, writes require approvals, every run emits a DecisionTrace
webmcp
Embed Char (UI optional)
<!-- Drop in Char runtime (UI optional) -->
<script
  src="https://<CHAR_CDN>/char.js"
  data-org="<ORG_ID>"
  data-app="<APP_ID>"
  data-mode="ui|headless"
></script>
The runtime auto-discovers tools and connects to the Tool Hub.

discovery: automatic
security: UI-bound
