The job, before and after this agent.

What it feels like today

  • “Turning a blog post into a thread means an hour of counting characters.”
  • “My threads start with filler and lose people after the first post.”
  • “Posting each reply by hand under the right post is fiddly and easy to get wrong.”

What you get with the agent

  • A numbered thread of 2 to 6 posts, each at most 300 characters, using only what your text says.
  • A hook as the first post and your call to action with the link as the last.
  • You edit, shorten or remove posts before approving.
  • Every post is checked in code before the first one goes out, so the thread is posted completely or not at all.
  • Posted as one reply chain, each post under the one before.

Before

After publishing a newsletter, the founder spends the evening chopping it into posts, renumbering them twice and replying to the wrong post halfway through.

After

She sends the newsletter text. A five-post thread with a strong opening and her newsletter link at the end is waiting in Reviews; she approves it and it's live as one thread.

How it works

The whole workflow, step by step.

Send an article, newsletter or notes from a form, your CMS or a manual run. AI writes a numbered thread of 2 to 6 Bluesky posts in your voice: a hook first, one idea per post, your call to action and link last, using only what the text says. The thread waits for your approval in Reviews, where you can edit, shorten or remove posts. Before anything is posted, code checks every post (at most 300 characters, no leftover placeholders), so the thread goes out completely or not at all; then the first post is published and each next post replies under the one before, with the same thread root. Bluesky only, text only; hashtags and @mentions appear as plain text.

This is the workflow that opens in your workspace when you set the agent up. Every step can be edited.

  1. Step 1New text to turn into a threadStarts when your form, CMS or a manual run sends a long text: title (optional), text (the article, notes or newsletter), link (optional, used in the last post).
  2. Step 2Write the threadAI turns the text into a numbered Bluesky thread of 2 to 6 posts: a hook first, one idea per post, a call to action with your link last.
  3. Step 3Approve the threadThe thread waits in Reviews: edit, shorten or remove posts (keep the numbering right), then approve to post it. Reject to post nothing.
  4. Step 4Check the whole threadIn code, before anything is posted: at least 2 posts, each at most 300 characters, and no leftover placeholders. A thread is posted completely or not at all.
  5. Step 5Ready to post?The whole thread passed: it's posted. Otherwise nothing is posted.
  6. Step 6Held: nothing postedA post was too long, missing or still had a placeholder. Fix it and send the text again.
  7. Step 7Post 1 (the hook)Publishes the first post; the rest reply under it.
  8. Step 8Is there a post 2?In code: does the approved thread have a post 2?
  9. Step 9Post 2?Post 2 follows, or the thread is complete.
  10. Step 10Post 2Replies under post 1 (the thread's first post is the root), so the posts read as one thread.
  11. Step 11Is there a post 3?In code: does the approved thread have a post 3?
  12. Step 12Post 3?Post 3 follows, or the thread is complete.
  13. Step 13Post 3Replies under post 2 (the thread's first post is the root), so the posts read as one thread.

  16. Step 16Post 4Replies under post 3 (the thread's first post is the root), so the posts read as one thread.

  19. Step 19Post 5Replies under post 4 (the thread's first post is the root), so the posts read as one thread.

Example run

What goes in, and what comes out.

Example with fictional data

Comes in

A 120-word note on three money leaks in small studios, with a newsletter link.

The agent produces

Five numbered posts: a hook about losing money on the same three things, one post per leak, the fix, and a last post inviting readers to the newsletter with the link. Approved and posted as one thread.

What you need

Everything it takes to run it.

About 10 minutes from purchase to live. A checklist above the canvas takes you through each step.

Plan

Included in Enterprise; on other paid plans it's $59 once. Agents run live on paid plans, from Basic ($39/mo).

Your AI key

Connect any of 15 AI providers on your own key. Your provider bills usage directly, at cost; we add no markup.

Apps

Checklist

  • A paid plan (agents run live on paid plans).
  • An AI provider key (Settings → AI Providers).
  • Bluesky, connected in Settings → Integrations (handle + app password).
  • A form, CMS or script that can send the text to a webhook (or run it by hand).

Setup, about 10 minutes

  1. Connect your AI provider. The AI steps run on your own key (OpenAI, Anthropic, Google and more). Add one in Settings → AI Providers.
  2. Connect Bluesky. Connect Bluesky with your handle and an app password (Settings → Integrations → Bluesky).
  3. Describe your voice. Open “Write the thread” and replace the placeholder with your voice and call to action.
  4. Pick your Bluesky account. Open each posting step (Post 1 to Post 6) and pick your Bluesky account.
  5. Test it with Dry Run. Press Dry Run: the agent runs on sample data with no messages sent and nothing written to your apps.
  6. Switch the trigger on. Open the trigger, copy the webhook URL and secret into your form, CMS or script, and switch it on. Fields: title (optional), text, link (optional).

FAQ

Questions about Bluesky Thread Builder.

Can it make up facts to fill the thread?

It's told to use only what your text says and to keep numbers and names exactly. If the text is too thin, it says so instead of padding.

What if something fails halfway?

The whole thread is checked before posting starts. If Bluesky refuses a post midway, for example because of its hourly limit, the earlier posts stay up and the run history shows where it stopped.

Does it work for Mastodon too?

No, this agent posts threads on Bluesky only, as text. Links are clickable; hashtags and mentions appear as plain text.

How long can the thread be?

Up to 6 posts of at most 300 characters each. Longer texts are condensed to the key points.

What if one post fails?

The whole thread is checked before the first post goes out. If Bluesky refuses a post midway (for example because of its rate limit), the posts before it stay up and the run history shows where it stopped.

Can it add images?

No, posts are text only for now. Links are clickable; hashtags and @mentions appear as plain text.

Is this a subscription?

No. Bluesky Thread Builder is a one-time purchase of $59 per workspace and never renews. The Enterprise plan includes it at no extra cost. Running it live needs a paid plan (from Basic ($39/mo)), and your AI provider bills you directly for usage.

Can I test it before it touches real data?

Yes. Once it's set up in your workspace, Dry Run plays every step on sample data with simulated AI and app calls: nothing is sent and nothing in your apps changes. Switch the trigger on only when you're happy.
