If what you want is somewhere to keep files next to your chats, use ChatGPT Projects. It does that well, and Canonly is not trying to replace it.
What Projects will not tell you is which of three drafts is the one you meant, that two of your documents disagree, or that the idea being suggested today is the one you turned down in March and wrote a reason for. Those are not gaps in Projects. They are a different job.
A memory keeps what was said. Canonly keeps what was settled, and works across Claude, Cursor and anything else that speaks MCP rather than inside one tool.
No, and it is not trying to. Projects is where you work. Canonly is where the conclusions live, so that they survive the conversation and follow you to whatever you open next.
Not necessarily, but the case is weaker. The clearest reason to use this with one AI tool is that it tells you when your own documents contradict each other, and answers a proposal you have already refused. If neither has happened to you yet, wait until it does.
That is the intended arrangement. Keep working in Projects. Canonly holds the documents and the decisions, and any AI that speaks MCP can ask it what is current, including from inside a conversation.
You take everything: every document, every version, every decision including the ones you refused, in a published and versioned format. On every plan, including the free one.
A folder holds files. This holds what you concluded about them: which one is current, which replaced which, what you turned down and why. That last part is the bit nothing else keeps, because the thing you refused never became a file.
