Executive Summary

CBrowser is an AI-powered browser automation platform. It simulates how real humans experience websites. Users with diverse cognitive abilities, disabilities, and decision-making patterns are all modeled. Unlike tools that test if buttons click, CBrowser tests if actual users can complete their goals.

Constitutional AI Safety

5-zone action classification blocks dangerous automated operations

Cognitive User Simulation

26 traits + 10 values model realistic human decision-making

Claude MCP Integration

120 tools, first-class Claude ecosystem support

Market Context

The Problem

Traditional automation tests if buttons click. It does not test if confused first-timers, impatient power users, or people with tremors can complete their goals.

The Gap

No other browser automation tool simulates cognitive diversity. Playwright, Puppeteer, and Cypress run scripts. They don't model human patience, frustration, or decision-making.

The Opportunity

AI agents need the same accessibility as humans with disabilities. Accessible sites are sites AI agents navigate well. CBrowser sits at this intersection.

What Makes CBrowser Unique

Three capabilities no other browser automation tool provides:

1. Constitutional AI Safety

5-zone action classification system

Every tool action is classified into safety zones. Dangerous operations need explicit approval. Prohibited actions are blocked. CBrowser is the only browser automation tool with built-in ethical constraints.

Green - SafeRead-only operations, screenshots, data extraction

Yellow - CautionNavigation, form filling, element interaction

Orange - ReviewSession management, state changes

Red - RestrictedSystem-level operations, requires explicit approval

Black - ProhibitedActions that could cause harm, always blocked

2. Cognitive User Simulation

26 traits + 10 values per persona

Each persona has 26 cognitive traits and 10 Schwartz motivational values. The system simulates realistic decision-making. When patience runs out, the persona abandons. When anxiety spikes, they hesitate.

3. Claude MCP Integration

120 tools via Model Context Protocol

Built for the Claude ecosystem. 120 MCP tools available via Claude AI connection. Native support for Claude Code, Claude Desktop, and any MCP-compatible client.
