    Find similar pages

    Restrict similar pages to the current space

    See the similar pages in a preview

    Even before creating a new page you can check whether the content is already published in the wiki and whether there are already matching pages for a publication.

    The targeted search in the current space allows to effectively find pages that might already contain the new information - even in mighty wikis.

    Page preview and highlighted terms from the page title enable a quick decision on whether the content of the new page has already been published.

    More details

    When creating a new wiki page, the Duplicate Content Defender will show if a page with similar title or even similar content already exists. Clutter is eliminated early on.

    This plugin allows us to avoid creating several different articles about the same topic. It finds similar articles and allows us to edit existing content before creating redundant content. Well Done!

    Paid-via-Atlassian pricing FAQ

    How does server add-on pricing work?

    Server products and add-ons are hosted on your servers. Licenses are perpetual and the purchase price include 12 months of maintenance (support and version updates).

    You can renew maintenance after 12 months at 50% of the current purchase price. You can upgrade the tier of your host product and add-on licenses at any time. Upgrade prices are calculated based on Atlassian's formula (view example).

    If add-on pricing changes after your initial purchase, there's a 60-day grandfathering period during which you can renew based on the old pricing.

    How do I determine my server pricing tier?

    The add-on tier should match the licensed user tier of the Atlassian host application. For example, if you have a Confluence Server license for 25 users, you should purchase the 25-user tier for add-ons. Even if fewer users want to use the add-on than your host application license, the two licenses should match exactly.

    Do you offer academic, community, or open-source licenses?

    For server add-ons, purchase and renewal is half-price if you have an academic license for your Atlassian host application. Server add-ons are always free for community and open-source licenses. Cloud add-ons do not have discounted or free licenses.

    For more details about qualifying for special licenses, see here.

    Can I extend my free trial?

    For server add-ons, you can extend your add-on trial up to 5 times - in other words, for up to six months. Extend your trial by generating a new evaluation license key from Atlassian Marketplace. Click Try it free and you'll be directed to generate a new license. Paste this license key into the add-on listing in UPM from your Atlassian host application, and you're all set.

    How can I buy add-ons for my legacy JIRA Server or Confluence Server license?

    If you own a legacy JIRA Server Unlimited (100+ users) or Confluence Server Unlimited (2000+ users) license purchased in 2012 or earlier, legacy add-on pricing is no longer available. You have two options for add-on purchasing:

    • Purchase the add-on at the non-legacy Unlimited (10000+ users) tier.
    • Renew your JIRA or Confluence license at a non-legacy tier, then purchase the add-on at the same tier.
