Get started

Three steps to go live. We'll check them off as you go.

  • Connect a social accountGo to Accounts and connect a platform.
  • Send your first postPublish a test post from Compose.
  • Connect your AI agent (MCP)Drop the config into Claude or Cursor.

Accounts

Connect each account you own through its official OAuth flow. PostWire only posts what you explicitly send.

Connected accounts

Manage the social accounts PostWire can post to.

Connect a platform

Pick a platform and connect it securely. No password is ever shared with PostWire.

Invite a client to connect Agency

Generate a secure link your client opens to connect their own account — no credentials shared with you.

Compose

One idea → the best native post for every network, in one click.

✨ Smart Distribute

Describe your idea, add media, pick platforms. AI writes a native post for each one — the right hashtags, length, SEO and format per network. Nothing is treated the same.

💡 Tip: your file is published exactly as uploaded — PostWire never re-encodes or crops it. For best results, TikTok / Reels / Shorts prefer vertical 9:16, YouTube long-form 16:9, and Instagram feed 1:1 or 4:5.

Applies to Instagram & Facebook. Stories and Reels need a photo/video (Stories take either).

🎙️ Brand voice (optional — makes every post sound like you)

Saved on this device and applied to every AI generation. The more specific, the more on-brand the output.

Your drafts — edit anything, then publish

TikTok — Direct Post settings

TikTok requires you to choose who can view it, interaction settings and content disclosure before publishing.

Connect your TikTok account in Accounts first.

Turn this on if your video promotes a brand, product or service.

API & MCP

Your key, a ready-to-run example, and the MCP config for AI agents.

API key

Use it server-side as Authorization: Bearer <key>. Keep it secret — never put it in client code.
