AI Mastodon Thread Generator — Free Tool

Turn one idea into a Mastodon thread of 5 to 8 numbered posts, each inside the per-post character limit and each able to stand on its own.

What is the thread about?

Real examples

Actual output from the assistant for Mastodon.

Mastodon threads are read across servers where the first post may arrive without the rest, so numbering and a self-contained opener matter more here than anywhere else.

Brief

how to read a train timetable properly, from someone who plans rail trips for a living

1/ People think a timetable tells you when the train leaves. It tells you rather more than that, and the extra is where the useful trips are.

2/ The footnotes are the timetable. “Saturdays only”, “change at”, “request stop”. Everything that makes a journey possible or impossible is in six point type at the bottom.

3/ A connection with a four-minute gap is not a connection, it is a hope. Twelve minutes is a connection. This is not in the timetable and it is the most important rule in it.

4/ Look for the trains that run once a day at an odd hour. They exist because somebody needs them, and they usually go somewhere the fast route does not.

5/ And read the previous year's version. What was cut tells you what is about to be cut.

Features

Between 5 and 8 numbered posts, each making one point of its own
An opener written to work alone, because it is all most people see
Every part sized to the per-post limit, never to the whole thread
Send the whole thing to the composer to edit and schedule it

How it works

Write a short brief — one line describing what you want. Specific beats broad: "winter blend, 20% off this week" gives a better result than "coffee promo".
Press Generate. It runs right here — no account, no card, three times a day.
Need more? A free account raises the limit to 50 AI generations a month.
Take the result wherever it needs to go. This one lives on the page rather than in the composer, because it is something you do once rather than every time you post.

What you get free

Three generations a day on this page, with no account at all. Signing up is free and raises it: the Free plan includes 50 AI generations a month, Pro includes 300 and Business includes 1000 — and you can buy credits on any plan if you run out.

An account doesn't change this particular tool — it runs the same way whether or not you have one. What it changes is everything downstream: once you've picked a name, a title, or an idea, the account is where you actually schedule and publish the posts that follow from it.

Getting better output

Put one concrete detail in the brief — a number, a name, a place. Generic briefs produce generic output.
Use the per-platform page, not the general one. The platform changes the length, the register, and in some cases the rules the result has to obey.
Run it more than once. Each run is independent, and the second attempt on a sharper brief usually beats editing the first.
Treat it as a first draft. The fastest workflow is generate, then change one line — not generate and paste.

Frequently asked questions

How long should a thread be?

Between five and eight posts. Under five it was a post you split up; over eight and most readers stop before the payoff. The generator writes in that range and numbers each part so the order survives a copy and paste.

Does the character limit apply to the whole thread?

No, and this is the mistake most AI threads make. Mastodon posts allow 500 characters on most servers, though individual instances can and do configure a different limit.

What makes a good thread for Mastodon?

Mastodon threads are read across servers where the first post may arrive without the rest, so a self-contained opener matters more here.

Do I need an account?

No — you get 3 free generations a day right on this page, no signup. A free account lifts the limit: the Free plan includes 50 AI generations a month, Pro includes 300 and Business includes 1000, or you can buy credits on any plan.
