X from Claude
Schedule X posts with Claude.
Add Buzzmark from Claude's directory, or with one command in Claude Code, and Claude writes X posts and threads of up to 25 posts in your voice, then schedules them on your Buzzmark calendar.
A free X account stops at 280 characters and a paid one takes 25,000, and Buzzmark checks which one yours is before a post is scheduled.
It's for founders and growing businesses that already work in Claude. It comes with every Buzzmark plan, and nothing posts on the spot: the earliest a post goes out is 5 minutes after you ask.
7 days free for new users.
Set up Claude

- 2Press Connect to Claude, then sign in and allow it on the Buzzmark page that opens.
- 3Then ask in your own words, in any chat.
Ask Claude for X posts.
Your own words work. These are examples for a made-up design studio.
Prompt 1 Turn this brief into an X thread in our voice and save it as a draft.
Prompt 2 Rewrite this post as a thread opener for X and put the thread on my next free slot.
Prompt 3 Which of our X posts did best last month, and what did they have in common?
X, without the mistakes X punishes.
Length by your X plan
Claude can write the long post. If the account is on X's free plan, Buzzmark stops it at 280 characters before it's scheduled.
One account per post
X bans the same words on several accounts. Buzzmark refuses a post to two X accounts, and words that already went to X in another post.
Threads of up to 25 posts
Ask for a thread and Claude saves each post in order. The whole thread goes out at the time you pick.
What X takes
Buzzmark checks every post from Claude against these and says what to fix before it's scheduled.
