ArkhamMirror

Connect the Dots Without Connecting to the Cloud.

ArkhamMirror is an air-gapped, AI-powered investigation platform designed for journalists and researchers. Running 100% locally on your machine, it transforms unstructured data into actionable intelligence using advanced Natural Language Processing (NLP), Vision AI, and Knowledge Graphs. This ensures that chaos is turned into order, all while maintaining absolute data privacy.

Key Features

ArkhamMirror offers a comprehensive suite of tools to enhance investigative workflows:

• Local AI: Engage with your data through Offline Retrieval-Augmented Generation (RAG) capabilities, ensuring sensitive information never leaves your environment.
• Semantic Search: Discover relevant documents based on conceptual understanding, moving beyond mere keyword matching.
• Knowledge Graph: Visualize intricate, hidden connections between entities such as people, organizations, and places within your dataset.
• Auto-Timeline: Automatically extract dates and events from various sources to accurately reconstruct chronological sequences of occurrences.
• Visual Table Extraction: Utilize advanced Vision AI models to recover and interpret complex financial tables and other structured data from PDFs and images.
• Contradiction Detection: Automatically identify and flag conflicting statements and inconsistencies across multiple documents, aiding in critical analysis.
• Absolute Privacy: Operates with zero cloud dependencies. Your investigative data remains entirely isolated within a specialized "Data Silo" on your local machine.

Try ACH Online – No Installation Required

For quick analyses, explore the standalone Analysis of Competing Hypotheses (ACH) tool, which runs entirely in your browser:

• Based on Richard Heuer's CIA methodology for evaluating competing explanations.
• All data resides solely in your browser's localStorage; nothing is ever transmitted to a server.
• Offers optional AI assistance via your own API keys (supporting OpenAI, Groq, Anthropic, or local Large Language Models).
• Export analyses in versatile formats including JSON, Markdown, or PDF reports.
• Ideal for swift evaluations without the need to set up the full ArkhamMirror platform.
