Shared context workspace for product teams and AI agents to collaborate using specific company data.
Kanwas is a shared context board and workspace designed specifically for product teams and AI agents. It serves as a living 'context brain' that holds a team's critical know-how, research, decisions, and data. Unlike traditional storage or isolated AI chats, Kanwas provides a spatial environment (canvas) where humans and AI agents collaborate. It integrates strategy docs, market signals, and agent workflows, allowing AI to execute tasks using real, specific company context rather than generic training data. The system is built on a Git-backed filesystem using plain .md files to ensure transparency and prevent vendor lock-in.

Visual workspace and session manager for building with Claude Code and Codex agents.
Nimbalyst is a comprehensive visual workspace and session manager designed specifically for building with AI agents like Claude Code and Codex.

By providing full project context to AI agents, Nimbalyst allows users to review, approve, or reject AI-generated changes in real-time. It features a session manager with a Kanban board, integrated task tracking that agents can update automatically, and visual tools for CSV editing, database schema design, and Mermaid diagrams. The platform aims to maximize collaboration bandwidth between humans and AI by eliminating context switching and providing high visibility into agent actions.
