The problem
How it works
A one-minute video from The Next New Thing presents Postiz as a scheduler that an AI agent can run end to end, and sketches a service built on it: take ideas from a client’s meeting notes, have an agent shape them into posts and schedule them through Postiz. Postiz’s documentation shows the pieces: install the postiz CLI from npm, sign in with a device code or an API key (pointing it at your own server if you self-host), then let the agent run commands to list connected accounts, create scheduled posts and upload media; an agent skill installs with npx skills add gitroomhq/postiz-agent. Postiz can be self-hosted under AGPL-3.0 or used as a paid cloud service.
Results and limitations
This is a short overview and documentation, not a reported project, so it is marked planned. The video says 34 platforms; the CLI documentation says 28 or more.
Before you try it
Self-hosting means creating your own developer app on each social network, and the README warns that approval from Meta, YouTube or TikTok can take weeks. Have the agent schedule posts for later rather than publish at once, so you can read each one first, and keep the API key out of shared scripts. Posts built from a client’s meetings need the client’s sign-off. Results depend on your setup and were not independently reproduced by Top 200 Repos.
Tools and repositories
No ranked repository is involved. This use case still stands on its own source.
- Tools
- Postiz · Node.js (for the CLI) · An agent such as Claude Code or Codex
- Prerequisites
- A Postiz Cloud account or a self-hosted Postiz server with your social accounts connected.
Try it yourself: Turn notes into posts for approval
Fill the fields to adapt the prompt. Empty fields stay as visible [placeholders].
Here are notes from [Source]: [Notes]. Write [Number of posts] posts in [Voice] for [Platforms], each within the platform’s length limit and with no claims that are not in the notes. Then list the postiz commands you would run to schedule them at [Times], but do not run them until I approve the text.Start with posts scheduled a day ahead so you can still edit them in the Postiz calendar.
