What Ink is
Ink is a shared whiteboard where people and AI assistants create plans, forms, diagrams, and pages on a live canvas. Collaborators can work on the same board, with changes attributed to whoever made them. AI edits are saved as checkpoints that users can roll back. Boards can collect form submissions, keep responses in board records, and export them as spreadsheets. Users can share a board by link, embed it on a website, or present it as a step-by-step walkthrough. Its MCP connection instructions cover Claude, Claude Code, Cursor, Windsurf, and other agents able to read a URL. Ink says it does not sell data, run server-side AI, or use boards or records to train models. It is an installable web app for iPhone and iPad, Android, and desktop browsers, but does not support offline editing. The Free plan is free and includes unlimited boards and agent collaborators, with interactive Pro blocks on 3 boards. Pro costs $5 a month and adds Pro blocks on unlimited boards, forms, records, and live data everywhere.
