Mastodon features in Nootti
Multiple servers
Active on mastodon.social and fosstodon.org? Connect both and publish to all accounts in one tap. The free version posts to two accounts at a time.
Media and accessibility
Attach up to 4 photos or one video, each with alt text. GIFs stay animated, and Nootti resizes photos to your server's limits.
Smart customisation
Tailor your message specifically for Mastodon, while keeping a different tone or variation for Bluesky or Nostr safely in the same composition window.
Privacy by design
All communication happens directly between your device and your Mastodon server. Nootti never sees your Mastodon password.
Your server's own limits
Nootti reads each server's character limit, media sizes, and attachment count. Links count as 23 characters, as on Mastodon.
Content warnings and quotes
Hide text behind a content warning, mark media as sensitive, and choose who can quote the post on servers running Mastodon 4.5 or newer.
Native iOS integration
Built for iPhone and iPad, with Split View, keyboard shortcuts, and drag and drop from other apps.
Post visibility
Choose public, unlisted, or private (followers only) per post. Nootti applies the stricter of the account's visibility setting in Nootti and your choice for the post.
How Mastodon visibility works in Nootti
To prevent accidental over-sharing, Nootti applies the stricter setting between two values: the Post visibility set for the account in Nootti, and the visibility you choose for the post in Current post settings.
For example, if the account's Post visibility is private (followers only), a post you mark public still goes out as followers only. To post publicly, change the account's Post visibility in Nootti's Settings ▸ Accounts first.
Frequently asked questions
How do I connect my Mastodon account to Nootti?
Enter your server (for example mastodon.social) and your username, then tap Grant access. Mastodon opens in the browser, where you sign in and approve Nootti. Nootti never sees your Mastodon password, and you can revoke its access under Preferences ▸ Account ▸ Authorized apps.
Can Nootti post to multiple Mastodon servers at once?
Yes. Connect accounts on different Mastodon servers and they all receive your post simultaneously, each within its own server's limits.
How does post visibility work in Nootti for Mastodon?
Each Mastodon account in Nootti has a Post visibility setting: public, unlisted, or private (followers only). You can also choose a visibility for a single post, and Nootti uses the stricter of the two. If the account is set to private and you pick public for a post, it goes out as followers only.
Does Nootti use my Mastodon server's character limit?
Yes. Nootti reads each server's own limits for characters, media sizes, and the number of attachments. Every link counts as 23 characters, as on Mastodon.
Does Nootti show my Mastodon home timeline?
No. Nootti focuses purely on the writing and cross-posting experience. For reading your Mastodon feed, we highly recommend dedicated clients such as Ivory or Mona.
