Arky (https://arky.so/) is an infinite whiteboard-style visual workspace combined with a chatbot to structure a project or ideas.

Elements can be generated via the chatbot (models from Claude, Gemini and ChatGPT available) or created freely on the board.
They can be organized by dragging and dropping, grouping, or nesting.
Each group or block can be queried in the chatbot.

The Focus mode focuses on a sub-topic and the Mindmap mode offers the architecture in the form of a mind map. The docs mode allows word processing-style writing with export markdown, pdf or word.

Free in beta and unlimited during this release.
