I had a conversation with a person on Twitter some time ago and yesterday I needed to reference it to remember something I’d promised to do. Scrolling through my timeline was too much of a chore, but I discovered Conweets, the really simple way to search for conversations between two Twitter users.
You just connect your Twitter account with Conweets, search using two usernames and the conversation thread appears, nicely formatted! If you want to save the conversation you can screenshot it:
Conweets is free, but needs donations to keep the conversations going – be sweet and send them a donation if you find them useful!
