ContentOS integrations: LinkedIn, X, Threads and HubSpot

ContentOS is a content operating system that drafts LinkedIn, X and Threads posts in your voice and turns engagement into replies and warm leads, and its integrations are what connect it to the places that work happens. LinkedIn is the core connection: it imports up to 150 of your recent posts as voice samples, publishes to your profile and company pages, and reads comments and reactions for the reply queue and warm contacts. X publishes posts and threads from the same calendar, Threads publishes through the official Threads sign-in, and each account, at $1,000 a month, covers one LinkedIn profile, one X profile and one Threads profile. HubSpot reads contacts, never writes, as a lead source for the email and SMS outreach every account includes. Other connections, such as Gmail for sending outreach email, Slack for lead alerts and Notion for draft context, are available inside the product. In practical terms, connect LinkedIn first and add the rest as you need them.
