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.

Welcome

Write one idea and get a post made for each network — publish it now or queue it for 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

You have accounts connected and no published posts. One post now takes about a minute.

    One idea in, a native post for every network out — edit, then publish or schedule.

    Post to
    Photo or video TikTok and Instagram need one; YouTube a video
    Add photos or a videoClick or drop · several photos make a carousel

    More options media link, Instagram format, brand voice

    Published exactly as uploaded — never re-encoded or cropped. TikTok, Reels and Shorts prefer vertical 9:16; YouTube long-form 16:9; Instagram feed 1:1 or 4:5. Several photos: up to 10 on Instagram, 35 on TikTok, 4 on Bluesky and Mastodon, 20 on LinkedIn; other networks get the first. PNGs become JPEG for Instagram and TikTok.

    Press Write the posts and each network gets its own version here — the right length, hashtags and format — ready to edit before anything goes out.

    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.

    Fill your week in 60 seconds

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

    Text only, to the networks ticked above that take text — TikTok needs a video or photos and YouTube a video per post.

    Queue

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