# per4mx - AI Visibility Platform

> per4mx measures and improves how generative AI models (ChatGPT, Claude, Gemini, Grok, Google AI Mode, Google AI Overview, Copilot, Perplexity, Brave) recommend B2B companies. Built by AMM StreamTech AG in Switzerland.

## What per4mx does

per4mx is the complete GEO (Generative Engine Optimization) platform for B2B companies. It tracks how 9 AI models recommend your business, identifies gaps in your visibility, and generates content to close those gaps.

## Core capabilities

- **9-model ranking analysis**: Queries ChatGPT, Claude, Gemini, Grok, Google AI Mode, Google AI Overview, Copilot, Perplexity, and Brave with web search enabled, capturing what real buyers see
- **Semantic extraction**: We don't just track positions - our AI analyses how strongly each model recommends you by evaluating mention frequency, endorsement language, sentiment strength, and caveats. A company listed first isn't always recommended most strongly.
- **Per-topic gap analysis**: For every topic where you don't rank in the top 3, identifies the exact reason and generates actionable fixes
- **Competitor intelligence**: Side-by-side comparison of your AI visibility vs any competitor, per topic and per provider, with weighted scoring
- **AI Portrait**: Extracts how each AI model perceives and characterizes your company across automatically discovered competitive dimensions (e.g. data quality, compliance, cost efficiency). Compares your perception radar against competitors who rank above you, and feeds dimension-level gaps directly into actionable content recommendations
- **Content generation**: Creates blog posts, landing pages, FAQs matched to your tone and language
- **Website health review**: Audits structured data, Schema.org, entity signals, and index presence on Google, Bing, DuckDuckGo
- **llms.txt management**: Generates and manages your llms.txt file for AI crawler discovery
- **Weighted visibility scoring**: Provider market share weights (ChatGPT 30%, Google AI Overview 25%, Google AI Mode 12%, Gemini 10%, Copilot 8%, Perplexity 5%, Grok 4%, Claude 3%, Brave 2%)
- **REST API**: 19 endpoints with API key authentication for programmatic access
- **MCP server**: 15 tools for integration with Claude, Cursor, and other AI development environments
- **Scheduled automation**: Ranking checks, reviews, and research run automatically based on your plan
- **Multi-language, multi-region**: Per-language queries across CH, DE, AT localities
