how to schedule Mastodon posts with PostAI
Mastodon's federated design means your account lives on a specific instance, and most schedulers don't handle that well. PostAI connects to any Mastodon instance with an access token you create in Preferences → Development, and schedules posts with media attachments.
Schedule public posts, unlisted posts, or followers-only posts, attach images with alt text, and set content warnings where appropriate — all on a queue that publishes automatically. Cross-post from X or Bluesky to reach the Mastodon audience without copy-pasting between apps.

PostAI isn't just a Mastodon scheduler. when you connect your Mastodon account, you get the full scheduler plus an AI writer guided by your voice profile, plus growth tools tailored to the platform. all 13 platforms are included in every plan — you're not paying extra for Mastodon.
