Quick Start

This guide takes you from a brand-new account to a published cross-post. It should take about five minutes.

1. Create your account​

Sign up at the app with an email and password or Google. See Create your account for the details.

2. Connect your first channel​

Head to Settings → Accounts and connect a social account. We use each platform's official OAuth flow, so you authorize access on the provider's site and we never see your password.

New here? Connect one channel to start. You can add more any time — and every plan includes a set number of connected channels.

See Connect a channel for the per-platform steps and required permissions.

3. Compose your first post​

Open Compose. Pick the account(s) you want to post to, write a caption, attach media, and — if you like — set a different caption per channel.

post.buzz validates the post against platform limits before it goes out. If a video is too long for a Reel, or an image is too large for X, you'll find out here, not after it fails.

See Publish your first post.

4. Publish or schedule​

  • Publish now to send immediately.
  • Schedule to queue it for a specific time.
  • Save as draft to come back later.

Scheduled posts appear on the Calendar, where you can drag, reschedule, and review everything in flight.

5. (Optional) Turn on an agent​

Once you've got a rhythm, you can hand parts of it to an AI agent — from drafting proposals for your approval all the way to autonomous posting within boundaries you define. Start in AI Agents.
