You can add hashtags to Posts, Chat messages, Articles, comments, Lessons and Sections, Events, and Questions & Polls on web or mobile.
To add one, type a # followed by text—just like on other platforms. You can include multiple hashtags in the same piece of content.
Hashtag Basics
Hashtags can include letters, numbers, or underscores. They can’t include other special characters (like & or $) or extra spaces.
As you type, you’ll see a dropdown showing existing hashtags. Continue typing to create a new one.
The color of your hashtag will match your Space branding.
Highlighted Hashtags
Hosts can highlight up to 100 hashtags in each Space.
The first 10 appear in the search dropdown; the rest appear under See All.
When someone searches or types a hashtag in a Space, the list of highlighted hashtags will appear automatically.
To highlight a hashtag:
Click the hashtag to view its search results.
Select Highlight.
Choose one or more Spaces where you want it highlighted.
Highlighted hashtags appear:
In the dropdown when you click the search bar at the top of a Space
In the right-hand column of the Feed (if the Feed is enabled)
To turn this off, go to Space Admin > Space Features > Feed, then toggle off Display Highlighted Hashtags.
Visibility and Access
If a member has access to the Space where content lives, that hashtag will appear in their dropdown as an option.
If they don’t have access, it won’t appear.
When someone clicks a hashtag, they’ll see search results for all content across the Mighty Network that includes it, sorted by relevance.
If a member doesn’t have access to a Space where tagged content appears, that content will not show in their results.
Members can see hashtagged content in Spaces that are visible to anyone.
To view all results for a hashtag across every Space:
Click Search in a Space.
Click the highlighted hashtag.
At the top of the results, de-select the Space filter to Search All Spaces.
Note: Search results include Posts and Articles with hashtags. They don’t include messages in Chat Spaces or Private Chats.
You can’t edit hashtags yet, but deleting a hashtag from a piece of content removes it from the system.
You can also sort hashtag results by Top, Newest, or Oldest.
Hashtag Prompt
When creating Posts, Articles, or comments on web (and on iOS or Android for Posts), you’ll see a prompt to add a hashtag.
A one-time tooltip explains this feature; once you select Got it, the tooltip won’t appear again.
Click the prompt to insert a # where your cursor is. As you type, a dropdown will appear showing hashtags— including any highlighted hashtags in that Space.
Hashtag List
To display a list of highlighted hashtags in a Space:
Go to the gear icon > Space Features > Hashtag List.
Toggle the feature on.
Rename it to anything you like—your custom name appears in the right-hand column (for example, “Hashtabs”).
This feature appears on web and mobile alongside other Space features like Chat and Discovery.
Clicking it shows a full list of highlighted hashtags in that Space.
Important: The Feed feature must be enabled for the Hashtag List to display.
To manage your highlighted hashtags, go to gear icon > Content Highlights > Highlighted Hashtags. From there, you can drag and drop to reorder or create a new highlighted hashtag.
Suggested Hashtags (AI Feature)
Suggested Hashtags is an AI-powered feature available on Community plans and up.
Suggestions appear in Posts, Articles, and more—especially in Spaces without highlighted hashtags.
Suggested hashtags appear with a sparkle icon.
