The most useful post idea often isn’t in a trending feed. It is in a note you wrote after a customer call, a voice memo on the way home, or a question that kept coming up in a meeting. The problem is remembering it when you sit down to write.

Idea sources are how X11 can bring some of that material into the drafting flow. In Settings → Idea sources, you connect an MCP server you control, choose the tool that exposes your notes, and opt in to using it for post ideas. You can choose which kinds of notes count. Memos are the starting point; calls and meetings require a separate choice.

When Slop Cannon considers ideas from your sources, it reads a small window of recent material and looks for something that could become a useful post. It should keep enough of the original context to avoid inventing your experience, and discard notes that are too thin or too private to draft from. The result is a candidate in your review flow, not an automatic publication.

That boundary is important. A meeting note can contain somebody else’s detail that was never meant for a public feed. Even when the subject is fair game, the angle may need your judgment. “The client asked about onboarding” is a note. A post needs your take on why that question matters, and you may decide there is no post there at all.

For now, this is an opt-in connection to a compatible source, rather than a magic pipe to every notes app. It depends on the server and tool you configure. If it returns awkward data, the resulting ideas may be awkward too. The review step is where you make the call.

The aim is straightforward: fewer forgotten thoughts, fewer posts made from nothing. Your own work should be the richest source of things you can say with confidence.
