How It Works

Set up in minutes. Research in seconds.

AI-Prowler sits between your files and Claude. It handles the indexing, embedding, and retrieval — Claude handles the thinking.

Index your documents

Point AI-Prowler at any folder on your PC. It extracts text from PDFs, Word docs, spreadsheets, emails, images (via OCR), and 65+ other formats, then builds a private ChromaDB vector database on your machine.

Ask Claude anything

Open Claude Desktop. Claude automatically discovers AI-Prowler’s 77 tools via MCP and uses them to search, expand, and reason over your documents — going as deep as needed to answer your question.

Access from any device

Subscribe for mobile access and your knowledge base travels with you. One activation code sets up a secure Cloudflare tunnel — use Claude.ai from your phone, tablet, or any browser to reach your documents.

Features

Everything Claude needs to know your business.

77 MCP tools. Zero cloud uploads. Your documents stay on your machine.

🔍

Agentic RAG Search

Claude drives the research loop itself — it searches, evaluates gaps, reformulates queries, and reads surrounding context until it has a complete answer. Far beyond keyword search.

🧠

Self-Learning Knowledge Base

Tell Claude to remember a business lesson, client preference, or process insight. It’s instantly searchable in future conversations — no retraining, no GPU required.

📱

Field Service Tools

Built-in route optimization, weather checks, job tracking spreadsheet integration, SMS and WhatsApp messaging for field crew — all from a Claude conversation.

🔐

Private by Design

Your documents never leave your PC. The vector database, embeddings, and all indexed content live locally. Only the text Claude retrieves passes through the Claude API.

👥

Multi-User Server Mode

Business subscribers get full server mode with role-based access control, per-user scopes, private collections, and an Admin tab for managing seats and assigning team members.

📄

65+ File Formats

PDF (with OCR for scans), Word, Excel, PowerPoint, email archives, images, code files, CSV, HTML, JSON, and more. Incremental indexing keeps the database in sync automatically.

Common questions.

Do I need a Claude subscription to use AI-Prowler?

A free Claude account works with Claude Desktop for local use. For mobile access via Claude.ai, you need Claude Pro ($20/month from Anthropic) because custom MCP connectors require a paid Claude plan. Claude Pro is separate from the AI-Prowler subscription.

Does my data leave my computer?

Your documents, the vector database, and all indexed content stay on your PC. The only data that leaves is the text of retrieved document chunks when Claude processes them via the Anthropic API — the same as any Claude conversation. AI-Prowler never uploads your files to any server.

How does mobile access work technically?

When you subscribe, we provision a Cloudflare tunnel to your PC and send you an activation code by email. Enter the code in AI-Prowler Settings → Remote Access and click Configure — everything sets up automatically. Your PC then has a permanent URL that Claude.ai can reach securely from any device.

What is the difference between Personal and Business?

Personal gives one person mobile access to their own knowledge base on one PC. Business adds server mode — a shared team knowledge base on a company machine — plus a personal AI-Prowler install for each team member. Each Business seat gets both: their own personal knowledge base and access to the shared company one.

Can I cancel my subscription?

Yes, cancel anytime. Your tunnel stays active until the end of the billing period. After cancellation, the local AI-Prowler Desktop app continues to work fully — you just lose remote mobile access.

How do I get started?

Download AI-Prowler Desktop for free, install it, and add your first document folder. Open Claude Desktop — it connects to AI-Prowler automatically. For mobile access, contact us to subscribe.
