Where Postel Is the Better Fit

You post on LinkedIn and X

You want the week written for you

On Professional, Postel writes a week of LinkedIn and X posts, including carousels, from your material and from posts that took off in your niche. You approve, edit or skip each one, and approved posts fill your posting slots.

You want ideas from posts that already worked

Postel has a searchable library of high-performing X posts. You can filter by topic and reach, see what a strong hook looks like in your niche, and write your own version.

You want to write from Claude or Cursor on the entry plan

Both products have an MCP server. Supergrow lists its MCP on the Pro plan. Postel's is included on every paid plan and covers LinkedIn and X. See the LinkedIn MCP server page.
