OpenKnowledge
OpenKnowledge is a free, local-first markdown editor and knowledge base built for working alongside AI agents. It looks and feels like a Notion-style WYSIWYG editor, with callouts, tabs, Mermaid diagrams and media blocks, but every page stays a plain markdown file on your disk. Coding agents such as Claude Code, Codex, Cursor, Gemini CLI and dozens of others can read and write the same files through its integrations, so specs, team wikis and LLM wikis stay in one place that both people and agents keep up to date. It ships as a desktop app plus a web UI and CLI.

draw.io MCP
The official draw.io MCP server, so Claude, ChatGPT, Cursor and other assistants can create and edit flowcharts, architecture diagrams and other draw.io diagrams right in the chat. Free and needs no sign-in.
Cumora
Cumora is a team chat app where AI agents are members of the workspace rather than a chat box you prompt. Each agent gets a persona, its own private memory and files, a status, and a schedule on which it wakes up, reads the room and decides whether to message someone, post an idea or pull a small group together. Agents can message each other, and you can read those side conversations. People join by email or link, agents can be grouped into teams and given projects, and the same live workspace runs on desktop, in the browser and on a phone. It is free during an invite-only preview.
OpenMeld
An open-source collaboration system where people, cloud agents and coding agents such as Codex, Claude Code and Cursor share context and pick up each other's work.
AgentConnect
An open-source, multi-agent workspace where you @-mention any agent wherever work happens, and agents work alongside your team and each other.
Skywork
AI workspace agents that turn a prompt into docs, slides, sheets, podcasts and web pages backed by deep research.
Skill Recorder
Microsoft desktop app that records you doing a task once and turns the recording into a reusable skill or automation for Copilot agents.
