Compare

A good fit for

Developers and organizations needing scalable, verifiable semantic graph infrastructure for AI agents and IoT devices.

Know the limitations

Requires user to have their own AI subscription to connect via MCP; AI is not provided by the app itself.

What you can do

Personal knowledge management with verifiable AI answers grounded in owned notes and code.

Features

Notes and code are stored as Markdown files owned by the user, with AI answers citing exact sources and signed histories.
Encrypted, revocable team brain allowing end-to-end encrypted knowledge sharing with instant access revocation and audit trails.
AI integration via Model-Context-Protocol (MCP) using the user's own AI subscription, with signed and reversible AI actions.
Automatic linking of related notes and visualization of knowledge as a 3D map to reveal hidden connections.
AIngle provides a semantic directed acyclic graph with signed links for verifiable history, combining features of distributed ledgers, graph databases, and edge computing.

Integrations

Supports AI models including ChatGPT, Claude, Cursor, and local models via MCP.
Mayros AI agent framework integrates with WhatsApp, Telegram, Slack, and 20+ other apps.

Platforms & data export

Notes and code are stored as standard Markdown files on the user's machine, ensuring no lock-in and easy backup or migration.
