Happy Monday, makers. X, formally Twitter, is having a sale of Twitter memorabilia. Some expected stuff like giant hashtags and Twitter birds is for sale, and there are more unusual things like an indoor barn from Montana. 

In today’s digest: 

• Someone call the Doc. Time travel is here

• Mad at your computer? See if you can do it better

• Creative block? AI has you covered

Ever since Marty McFly and the Doc graced the big screen in ‘Back to the Future,’ society has been captivated by the thought of time travel. Imagine hopping into your own suped-up DeLorean and zipping back to 1955. 

That’s why Backtrack caught our eye. It’s kind of like time travel, just on a smaller scale. 

Record backwards: Backtrack is a Mac app that lives in your menu bar. It records your screen and audio backwards, so you can catch those unexpected moments that you might otherwise forget, and uses AI to generate notes and summaries. It can help you for meetings, interviews, presentations, and more.

According to co-founder Jordan Walker, Backtrack originally came into being way back in 2019. On a flight home from SF after a rough VC meeting, the team realized they had no real way to look back and remember important moments that had already happened, and they decided to get to work. 

Locally-stored: Early users seem to love their newly founded time-travel abilities.

“I've been using Backtrack since the V1 and found it an invaluable tool as a startup founder! Key use cases are when doing customer interviews, sales/bd and fundraising. I love that it's private, and you can set the data to delete after a period of time.” said Amadeo Pellicce.
