AI Mastodon Hashtag Generator — Free Tool

Features

• Generated from your caption, not a single keyword
• Uses the tag count Mastodon actually rewards
• Mixes broad reach with specific niche tags
• Appends straight onto the draft in the composer

How it works

1. 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".
2. Press Generate. It runs right here — no account, no card, three times a day.
3. Need more? A free account raises the limit to 50 AI generations a month.
4. It also moves generation into the composer, next to your channels and schedule — several variants per platform, then edit and schedule without leaving the page.

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.

The reason to sign in isn't the limit, it's the workflow: generations happen where your drafts, channels, and schedule already are, so you go from brief to scheduled post without copying text between tabs. This page gives you one variant; the composer gives you several, plus improve, shorten, expand, and tone.

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.
