Free Bluesky Post Generator

Custom feeds are the discovery layer

Bluesky’s default feed is chronological from the accounts you follow, so nothing is pushed to strangers there. What reaches new people instead are custom feeds: collections built by users, subscribed to deliberately, and frequently organized around a topic. Many aggregate posts by hashtag or keyword. That gives writing a specific mechanical purpose here, since a post that clearly declares its subject can be picked up by a feed with a standing audience, while a post that could be about anything stays entirely within your existing followers.

How to write for aggregation

Clarity of subject does more here than cleverness.

• Name the topic explicitly rather than alluding to it, since feeds match on words rather than intent.
• Add one or two topic tags, remembering they count toward your 300 graphemes.
• Keep the tone informal, because Bluesky culture reacts badly to posts written as announcements.
• Use the room you have, since 300 graphemes is more than X gives you and a very short post wastes it.
• Watch the grapheme count rather than a character count, especially when using emoji.
• Reply to people, since conversation is how most accounts get seen on a chronological platform.

Chronological feeds change the calculation

This is the biggest practical difference from an algorithmic platform.

• A post exists in the moment you send it and then moves down, rather than being surfaced later by a ranking system.
• That makes posting time a direct input to reach, in a way algorithmic platforms smooth over.
• It also means consistency matters, since being present when your audience is scrolling is most of the job.
• Custom feeds partly compensate by giving posts a second route beyond the immediate moment.
• Because feeds are opt in, the audience reached through one is smaller but considerably more interested.

Who uses this tool

People rebuilding an audience on a differently structured platform.

• People who left X and are adjusting to a chronological feed.
• Journalists and writers, well represented among active accounts.
• Developers interested in the open protocol underneath.
• Anyone whose posts never travel beyond their existing followers.
• People unsure how to get picked up by custom feeds.

Bluesky post specs

The limits and the discovery structure.

Bluesky is developing quickly and its feed behavior continues to change. Checked September 2026.

When this is not the right tool

The tool cannot see which custom feeds currently exist or which are actively subscribed to, and that landscape shifts as people build and abandon them. Checking on the platform is the only way to know what a topic will reach. Bluesky is also a smaller network, so numbers are lower for reasons unrelated to your writing, and timing matters more than phrasing on a chronological feed. For refining a draft, use the Bluesky caption generator, and the Bluesky hashtag generator handles the tags.
