01Thread
"Turn this 800-word essay into an X thread — strong hook, one idea per tweet, 7 tweets max."
Antwork drafts the thread, numbers it, validates each tweet under 280 chars, and queues it.
Post on X without leaving your AI.
Threads, hot-takes, real-time hooks. Antwork keeps you under 280 characters, splits long takes into threads, and ships them when your audience is awake.

Tell your AI. Antwork posts on X.
These are real prompts you can paste into Claude, ChatGPT, Cursor, or any MCP-aware AI. Antwork handles the API call, formatting, scheduling, and delivery confirmation.
02Live launch
"Schedule launch-day tweets every 30 minutes from 4–6pm — pull from these talking points."
Five sequential tweets timed to your window, each with the right hashtag and CTA.
03Hot-take
"Quote-tweet this with a sharp counterpoint in our brand voice — keep it under 240 chars."
A draft quote-tweet ready to publish, never above the character limit, never off-brand.
X limits, as the server enforces them
Posts are capped at 280 characters, and the cap is enforced when you schedule or publish, not silently truncated. X counts weighted rather than by character: every URL counts as 23 regardless of length, and non-Latin characters count double.

- — 4 media items per post, in total.
- — Images and video can never share a post. Ask for both and it has to be split into two.
- — A document cannot be attached alongside other media.
These numbers are read at build time from the same rules file the publishers validate against, so this page cannot claim a limit the server does not enforce.
