Twitter-Misskey Crosspost

Chrome extension for crossposting from Twitter (X) to Misskey

Twitter-Misskey Crosspost is a Chrome extension that automatically posts your Twitter (X) tweets to Misskey as notes. With just a single tweet, the same content will also be reflected on Misskey. No more copy and paste. --- ☆Main Features --- ● Automatic Crossposting When you post a tweet, it is automatically sent as a note to your configured Misskey instance. ● Full Media Support Images, videos, GIFs, and polls are transferred to Misskey together with the text. ● Thread Support Self-replies (threads) on Twitter are also crossposted on Misskey as replies to the original post. ● Quote Tweet Support Quote tweets are crossposted together with the text of the quoted tweet. ● Deletion Sync When you delete a tweet on Twitter, the corresponding Misskey note is also automatically deleted. ● Multi-Instance Support You can connect to any Misskey-compatible instance, such as Misskey.io, Misskey.design, nijimiss.moe, and others. ● Multi-Device Support As long as you are signed in with the same Google account, your settings will be automatically synced even when using a different device. --- ☆Additional Features --- ● Crosspost Toggle A toggle button appears next to Twitter’s tweet button, allowing you to quickly turn crossposting ON/OFF for each tweet. ● Crosspost Indicator A small icon is displayed in the timeline for tweets that have already been crossposted. You can see at a glance which posts have been crossposted, and clicking the icon will take you directly to the corresponding note on Misskey. ● Note Visibility Settings You can choose the visibility of crossposted notes on Misskey from Public, Home, or Followers-only. ● Sensitive Content Support Twitter’s sensitive media flag is automatically applied to the corresponding Misskey note as well. If sensitive settings are explicitly configured on the Misskey side, those settings take priority. --- ☆How to Use --- Install the extension. Click the extension icon and enter your Misskey instance URL. Click “Authenticate” and follow the on-screen instructions. After authentication is complete, click the extension icon again and then click “Click after authentication is complete.” Turn the crosspost toggle ON. Just tweet as usual, and it will automatically be posted to Misskey as well. --- ☆Notes --- ● To support thread syncing and deletion syncing, the mapping between tweets and posts is stored on your device. In theory, this mapping can be retained for up to about 1,000 entries, but once that limit is exceeded, older entries are automatically deleted first. ● After the above mapping has been deleted, or for tweets made before this extension was installed, deletion syncing cannot be performed. Mentions in those tweets will be crossposted as quote posts of the tweets. ● Replies to other users or tweets containing "@" are not crossposted. This is because Twitter (X) user IDs and Misskey user IDs are often different. This prevents accidental crossposting.
