    Content Inbox (brand memory)

    Add links, articles, ideas, and screenshots to Brand Inbox or General Inbox, then turn Brand Inbox items into drafts.

    Inbox in the sidebar opens Content Inbox: “Your second brain for content ideas and brand memory.”

    Capture material here, then generate a post from a Brand Inbox item or attach items to a Planner idea card.

    Brand Inbox vs General Inbox

    Tabs at the top:

    • Brand Inbox — scoped to the active brand. Use Create Post here.
    • General Inbox — shared across brands. AI can use it as extra memory when you generate from a Brand Inbox item. There is no Create Post on General Inbox cards.

    Switch brands with the sidebar footer switcher before adding Brand Inbox items.

    Add an item

    1. Open Inbox.
    2. Choose Brand Inbox or General Inbox.
    3. Click Add New (bottom right), or Add first item on an empty inbox.
    4. In Add to inbox, pick a type, fill the form, click Save.

    If the quota is used up, the button reads Inbox full and opens an upgrade prompt.

    Types you can add

    LabelWhat you enter
    Quick NoteOptional Title, What's on your mind?, optional Link
    Content IdeaOptional Title, Your content idea, optional Link
    ArticleTitle, Article body (plain text), optional Link
    LinkTitle, Notes, optional Link
    Work UpdateWhat happened?, What did you learn?
    Customer FeedbackFeedback, Source

    Generated is a filter for AI-generated images and videos that land in the inbox. You do not pick it in Add to inbox.

    Filters: All, then each type above. Views: feed or board (icons top right).

    Screenshots, images, and videos are stored privately. Upload succeeds when the file is stored. Image description runs on stills in the background and does not affect that. If it is still running, you can wait for a richer source, or create a post from the file as-is. If it fails, the file stays in the inbox.

    Turn an item into a draft

    Only on Brand Inbox:

    1. Click Create Post on the card.
    2. In Create post from inbox, choose:
      • Give a specific direction — required What should this post focus on? (max 300 characters). Optional Content pillar.
      • Let AI decide from inbox context — uses the item plus General Inbox memory.
    3. Click Create post.

    You land in the post editor. Toast: Post draft created from inbox.

    With Require approval on (default), the AI draft is Needs approval and shows in Approvals. With it off, the post is approved immediately and appears on Scheduler if it has a time.

    Attach inbox items to the Planner

    On a weekly idea card:

    1. Click Attach source.
    2. Pick a Brand Inbox item and click Attach.
    3. Click Generate Post when you want a draft grounded in that source.

    Up to 3 sources per idea card. Toast: Post draft created using attached source.

    Deleting an inbox item does not delete linked posts. Plan attachments keep their own content.

    Limits

    Inbox items are a plan cap across all Brand Inboxes plus General Inbox:

    PlanInbox items
    Creator100
    Pro500
    Team2,000

    The dialog Inbox limit reached reports used/cap. Delete items or upgrade (Settings → Billing). Deleting a post does not free inbox quota.

    If this fails

    • Select a brand first. Active brand missing; pick one in the switcher.
    • Each idea card can have at most 3 attached sources. Remove one first.
    • Create Post missing. You are on General Inbox; switch to Brand Inbox.
    • Generation quota dialog. Weekly AI posts allowance is used; wait for next week or upgrade.
