How it works
How to use the Mastodon Post Generator
- 1
Describe the post
The idea, the news or the question, in a sentence or two.
- 2
Pick a tone and a goal
Twelve tones, and a goal: replies, a click, a sale or a boost.
- 3
Copy your favorite
Each post shows its length against the 500 limit and how it looks in the timeline.
Mastodon post rules
What makes a Mastodon post work
The generator writes with these in mind, so what you copy is ready to post.
- 1
500 characters
The limit on mastodon.social and most servers. A link counts as 23 characters, however long it is.
- 2
Hashtags do the finding
There’s no algorithm picking posts for people. Hashtags are how they find yours, so the generator adds up to three.
- 3
CamelCase hashtags
#AutumnCoffee instead of #autumncoffee, so screen readers read each word. The generator writes them that way.
- 4
Boosts, not virality
Posts spread when people boost them. Useful, kind and specific posts get boosted; marketing voice doesn’t.

Mastodon Post Generator FAQ
Questions, answered.
How long can a Mastodon post be?
500 characters on mastodon.social and most servers. Some servers allow more. The generator stays under 500 and shows the count.
Is the Mastodon post generator free?
Yes. You can generate posts without signing up. We only use what you type to write them and don’t store it.
Do hashtags matter on Mastodon?
More than on most networks. People follow hashtags and search by them, so a few specific ones help the right people find your post.
Should I use a content warning?
Many servers expect one for some topics, like politics or spoilers. Add it in the composer after you paste the post.
Can I post the same idea to Bluesky and Threads?
Yes. Write a version here for each network. In Postivate, one post gets a tailored version for Mastodon, Bluesky, Threads and every other network you publish to, and each one is scheduled for the time you pick.
