ShareCube turns what ChatGPT writes into a real document you can share and get feedback on.
Ask ChatGPT to draft a plan, a report, or a page, and it publishes to ShareCube as HTML or Markdown with its own URL. You choose who sees it: keep it private, share it inside your organisation, or open it to anyone with the link.
Reviewers highlight a sentence and comment on it, the way they would in a document. ChatGPT can read those comments back and revise. Every version is kept, so you can see what changed and restore an earlier one.
It's useful when the people reviewing your work don't use ChatGPT themselves, when review comments would otherwise be scattered across a thread, and when you want the things an agent wrote to still be findable next month.
Free to start. The same documents are reachable from Claude, Cursor and other MCP clients, so you aren't locked to one assistant.
