User Web Server Tools

• Tools such as Tweet Nest function by backing up tweets on the user's Web server for later access. These tools also have the ability to search for particular posts. Users require basic knowledge of their hosting environment to set up such tools.
  
  

Third Party Services

• There are numerous third-party services, including Tweetake, TweetDumpr, Tweetscan, BackupMyTweets and TweetBackup. Some, such as Tweetake, are for personal archiving only, as they don't allow reimporting posts back to Twitter. Tweetscan has the added advantage of downloading user message archives to CSV files.
  
  

Desktop Software

• The Archivist is desktop software that allows Windows users to create searches about tweets that they can archive to their PCs. The program includes a visual display showing who is tweeting most about a subject.
  
  

Hashtags

• Online tools like Twapper Keeper archive tweets using hashtags. After the user submits a query, the tool scans Twitter for the tag and archives tweets on its servers. The user can place the archived tweets into categories.
  
  

Plugins

• Plugins for archiving tweets include Twitter Tools, for WordPress blog, and Twinbox, for Outlook. Twitter Tools can send tweets to the user's blog for archiving, but can also send updates about the blog to Twitter. Twinbox sends tweets and updates to the user's Outlook inbox, enabling searching, archiving and grouping of posts.
  
  

Calendar Tools

• Services such as Twistory can archive tweets into the user's calendar application. The service works with iCal, Google Calendar, Outlook, Thunderbird and others that have a similar layout. The service imports tweets at the moment of posting, and can import back to the user's first tweet.
  
  

Lifestream

• Applications utilizing lifestreaming include SweetCron, AmpliFeeder and Storytlr, hosted on the user's server. AmpliFeeder can also create XML files for social network streams data. Storytlr has the added feature of allowing users to add their own content to the service.
  
  

RSS

• RSS feeds are one of the easiest ways to back up tweet archives. The user can add the RSS feed to his RSS reader and use the search to look for items by keywords or phrases. Readers, such as Google Reader, allow users to retrieve items as far back as the first in the subscription.
  
  

Selective Archiving

• Evernote allows users to send messages and DMs to the application for permanent archiving. The user must insert "@myEN" into the body of a tweet to store the selected tweets.
  
  

Apps
