Cognithor

Cognithor is an open source agent operating system that runs AI agents on your own machine. It connects 19 LLM providers to 145 MCP tools across 18 communication channels, including Telegram, Discord and Slack, and positions itself as a private replacement for hosted assistants, with no telemetry and data kept on the local system. The core is licensed under Apache 2.0. It is aimed at developers and technically minded users who want agents that research, monitor and act on their behalf without a cloud subscription. Capabilities include a six tier memory system spanning identity, core memories, a knowledge base for retrieval, episodic logs, an entity graph and a tactical working set; a planning, execution and checking loop across three cooperating agents; gated and auditable tool modules covering web search, shell, file system, code editing and review, browser control, vision and speech; and built in, generated and community skills. Scheduled jobs and a kanban board let agents run recurring work. The core operating system is a free download. Paid Agent Packs add specialised agents that run fully locally with lifetime updates, founder support and a 14 day money back guarantee. The Deep Research Analyst pack is shown at €65 against a crossed out €119, and the Reddit Lead Hunter pack at €75 against €129. Other packs, such as Content Creator OS at €79 and a relationship tracking pack at €89, are listed as coming soon with a notify option. The project is available in English and German and publishes numbered releases with release notes on its site.
