X (Twitter)

Buzzator posts single tweets and full threads to X, with support for images, video, polls, and per-post reply controls. Your caption limit depends on the X subscription tier of the connected account — Buzzator detects it when you connect. This page covers the rules and the options unique to X.

Formats and limits

Setting Limit
Caption 280 characters (up to 4,000 / 25,000 on Premium)
Formats Single tweet, thread
Images Up to 4 per tweet
Video 1 per tweet
Thread Up to 25 tweets
Alt text Up to 1,000 characters per image
Publishing rate About 200 posts per 15 minutes

Caption length depends on your X plan

X's character limit scales with the account's subscription, and Buzzator reads your tier at connect time:

Tier Caption limit
Standard (no subscription) 280 characters
X Premium / Premium Basic Up to 4,000 characters
X Premium+ Up to 25,000 characters

Reconnect if you upgrade

Buzzator detects your tier when you connect X. If you upgrade or downgrade your X subscription later, reconnect the account so the caption limit updates to match.

Images or video — not both

A single tweet can carry either up to 4 images or exactly one video — never a mix of the two. If you attach both, X expects the video as the sole attachment.

  • Video (standard account) — up to about 512 MB, up to 140 seconds.
  • Video (Premium) — up to about 8 GB, up to 3 hours.

Threads

Set the format to thread to publish a chain of tweets, each replying to the one before it. You can build up to 25 tweets in a thread. Images can go on the first tweet only, or be distributed one per tweet.

If a tweet mid-chain fails to post, Buzzator flags the thread as partially published and links you to the first tweet, rather than silently claiming it all went out.

Polls

Attach a poll to a tweet:

Poll setting Limit
Options 2 to 4
Length per option Up to 25 characters
Duration 5 minutes to 7 days

A poll can't share a tweet with media

X doesn't allow polls and media on the same tweet. If you attach media, the poll is dropped.

Who can reply

X lets you gate replies on a per-post basis. Choose who can reply when you compose:

Option Who can reply
Everyone Anyone (the default)
Accounts you follow Only people you follow
Only accounts you mention Only users tagged in the tweet
Verified accounts Only verified users
Your subscribers Only your subscribers

Reply settings apply to the first tweet of a thread; the rest of the chain inherits it.

Other options

  • Made with AI — flag a post as AI-generated.
  • Paid partnership — mark a post as a paid partnership.
  • Community — route the post into an X Community by pasting the community URL; Buzzator also shares it to your followers' timelines.
