PostWire

Start posting everywhere

One idea becomes a different post for each network — then publishes, or waits in a queue until the day you picked.

  • Free forever for one brand — all of its networks, 30 posts a month, no card
  • TikTok included on the free plan, which most tools do not do
  • Two minutes to your first post: connect an account, write one line, publish

We email you a link to confirm it is your address — no password to invent.

Your first post, in about two minutes

Write one idea. See the post each network gets — before connecting anything. Then connect one network and publish it.

What do you want to say?

One or two sentences is enough — what you shipped, learned, noticed or want to ask.

Connect one network to publish

Start with one that takes plain text — you can add the rest later and every idea is rewritten for each.

Confirm your email to connect a network We sent a link to your inbox. Your drafts are saved here while you do.

Publish your first post

This is the version written for your network. Change anything, then publish.

Plan your week from one topic

PostWire writes five different posts — a lesson, a mistake, a number, a question, behind the scenes — and queues one a day. Edit or cancel any of them later.

Confirm your email to connect accounts

You can look around freely. Connecting a social account and publishing need a confirmed address — that is what stops someone using your email to post as you.

One quick question

How did you come across PostWire? It decides what we build next — and it is the only thing we will ever ask you.

Your accounts are connected — nothing has gone out yet

Setup

Four steps from an idea to a planned week.

Using an AI agent or n8n?

Your agent can post through PostWire with the same key: the MCP config and a curl example are ready in API & MCP.

Accounts

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

Connected accounts

Grouped by brand. A brand is one business with all of its networks — your plan counts brands, not networks.

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.

or schedule it:

⚡ Fill your week in 60 seconds

One topic, five different angles, one post a day for the next five days — queued and gone. This is the thing that keeps an account alive on the days you are busy.

Post at

Uses the accounts you ticked above. Text-only, so pick networks that accept text — TikTok and YouTube need a video per post.

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.

Queue

Everything you have scheduled. Posts go out on their own — you do not have to be online.

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.

All your keys

Rotate a key if it ever leaks: create the new one, switch your code over, then revoke the old one. Revoked keys stop working immediately.
