Materials

Not in the sidebar. The entry is the Materials (素材库) button at the top right of the Scheduled Broadcast and Bulk DM pages.

Six types: Text (文案), Image (图片), Voice (语音), Video (视频), GIF, File (文件). Organize them with tags; filter by type and tag, and search by text content.

Adding

Entry	Description
New material (新建素材)	Text is one per line and created in bulk on save; other types are uploaded as files. The type cannot be changed after creation
Bulk import (批量导入)	Drop files or a whole folder; items are classified automatically by extension, and .txt files are split line by line into multiple text items. Up to 2000 files per batch, identical content is deduplicated automatically, and the whole batch shares one set of tags

Text also supports random variants and Premium emoji.

Using

• Import from Materials (从素材库导入) below the text box
• The Materials button next to images, voice and DM attachments

Using is copying: the content is copied into the task, so editing or deleting the material afterwards does not affect tasks already created.

Usage count (使用次数) in the list records how many times an item was picked, not how many times it was sent.

Managing

Select multiple items to add tags, remove tags, or delete in bulk. Rename or delete tags under Manage tags (管理标签).
