Postprism is a Bluesky scheduler that publishes your posts at the time you set, even when you’re offline. Write a version of up to 300 characters with clickable links, mentions and hashtags, connect with an app password, and plan Bluesky on one calendar beside X, LinkedIn and three other networks.
Three steps from draft to published, with an app password instead of your main Bluesky password.
Create an app password in your Bluesky settings, name it Postprism, then enter your handle and that password on the Platforms page. You can revoke it in Bluesky at any time.
Write the post once, then shape its Bluesky version within 300 characters. Links, @mentions and #hashtags you type become clickable, and Enhance with AI can draft the short version when you want help.
Pick the date, time and time zone, and schedule. Postprism publishes on time even when you are offline, and you can reschedule it from the calendar until it goes out.
Postprism posts through the AT Protocol, the same way Bluesky’s own app does, so your post looks like one you wrote by hand.
Up to 300 characters, with your line breaks kept. The composer counts the Bluesky version as you write.
300 characters
Paste a URL into the text and Postprism publishes it as a clickable link, so readers can open your article or product page.
Clickable in the post
Type @handles and #hashtags in the text. Postprism looks up each handle when it publishes, so mentions notify the people you tag and hashtags lead to their feeds.
Detected automatically
The limits that decide whether a scheduled Bluesky post goes out cleanly, with a source for each figure.

The same options are in the composer, the REST API and the MCP server, so a post scheduled by your AI assistant can be set up exactly like one you wrote.
Edit the Bluesky text apart from your other networks, with its own character count. Reset to base brings back the original draft.
Write them straight into the text. Postprism makes each one clickable when the post publishes.
Each workspace connects its own Bluesky handle, so every brand or client posts from the right account.
Pick the exact time the post should go out. Open it on the calendar to reschedule if plans change.
Building with the API? Every field, with an example request, is in the Bluesky platform guide.
One post becomes a short Bluesky version beside the versions for your other networks. The calendar holds it until its time, then Postprism publishes to Bluesky and the rest together.
Post the same update to Bluesky, X and LinkedIn, each in its own words, without switching apps or logins.
Select Bluesky, X and LinkedIn on the same post. Each gets its own version and goes out at the time you scheduled.
Postprism uses an app password you create for it, not your main Bluesky password. Revoke it in Bluesky whenever you like.
Keep each brand in its own workspace with its own Bluesky account, calendar and brand voice. Solo includes 1 workspace, Freelancer 3 and Agency 10.
Invite teammates as Owner, Admin, Editor or Viewer. Freelancer includes 3 team members and Agency 10.
On Freelancer and Agency, Editors submit posts for review and an Owner or Admin approves them or asks for changes before they are scheduled.
See Bluesky posts beside LinkedIn, X and the rest in month, week and day views, and reschedule any post from its dialog.
You write the post. When you want help, AI drafts the Bluesky version in your brand voice, and you edit it before anything is scheduled.
Enhance with AI rewrites your base post for each network you selected, so a LinkedIn post becomes a tight Bluesky version under 300 characters.
Set your tone and values once on the Brand page. AI adaptations follow them on Bluesky and every other network.
AI suggestions land in the editor. Review and edit each version, or skip AI and write every word yourself.
150 AI adaptations a month on Solo, 500 on Freelancer and 2,000 on Agency.
Postprism runs an MCP server, so Claude, Cursor, Gemini CLI and other MCP clients can draft and schedule Bluesky posts in your workspace. Every post lands on your calendar.
Add the Postprism MCP server to your assistant and sign in with your Postprism account. It works on every plan, including the free trial.
Bluesky has the platform key bluesky, so the assistant posts exactly where you asked, next to X, LinkedIn or any other network.
Without a date, create_post saves a draft for you to review. With scheduled_at, the post is scheduled and publishes automatically.
n8n and your own scripts use the REST API with an API key, on the Freelancer and Agency plans.
Write five Bluesky posts under 300 characters from our launch notes, one a day from Monday at 10 AM, and schedule them.
