Good to know

  • Illumipost reads your server's limits when you connect, so the composer checks against the real numbers.
  • Requested permissions: read your account, write statuses and upload media. Nothing else.
  • Publishing uses Mastodon's Idempotency-Key header, so a retry can't post twice.

How AI helps on Mastodon

Write one base post, or start from a link. Adapt for each network produces a Mastodon version within the limits above, and you can rewrite it for tone or ask for hashtags and alt text. Check your length first with the free character counter.
