Archive Only Mode
Archive Only Mode is a limited version of Cyd that lets you use the features that are possible without having access to sign into an X account. If you can still sign into your account, continue to Dashboard instead.
To continue, you'll need to have already requested your X archive from X, and then downloaded it, before deleting your X account.
And in order to migrate your tweets to Bluesky, you'll also need a Cyd premium plan.
Start by clicking Continue to Import X Archive.
From here, browse for your X archive, and then click Start Import.
After the import succeeds, click Go to Dashboard. When you're in Archive Only Mode, the dashboard is limited to only features that work without a signed in X account, which right now is just Migrate to Bluesky.
Click Migrate to Bluesky to migrate your tweets to Bluesky. For more information, see Migrate to Bluesky.
