Kosmik

Kosmik was an infinite-canvas visual workspace and AI moodboarding app for macOS and Windows, published by Lithium Media SAS in Paris and backed by Creandum. It organized work into spatial "universes" grouped in shared workspaces, and combined that canvas with a built-in web browser, web clipper, PDF reader, drawing and frames, real-time multiplayer collaboration, and AI features including auto-tagging, AI search and AI-assisted asset discovery. Kosmik was an early mover on local-first storage, shipping an on-device IPFS node with multiplayer in 2018 and a multiplayer web browser in 2022, before consolidating that work into Kosmik 3 in 2025. Kosmik shipped no public API, SDK, CLI or webhook surface, and the product sunset on 31 May 2026; the vendor now publishes in-app universe and workspace export instructions in place of any migration interface.

Kosmik is profiled on the APIs.io network. Tagged areas include Company, Consumer, Productivity, Visual Collaboration, and Infinite Canvas.
