New Mac App Wants To Record Everything You Do - So You Can 'Rewind' It Later (arstechnica.com) 41

An anonymous reader shares a report: Yesterday, a company called Rewind AI announced a self-titled software product for Macs with Apple Silicon that reportedly keeps a highly compressed, searchable record of everything you do locally on your Mac and lets you "rewind" time to see it later. If you forget something you've "seen, said, or heard," Rewind wants to help you find it easily. Rewind AI claims its product stores all recording data locally on your machine and does not require cloud integration. Among its promises, Rewind will reportedly let you rewind Zoom meetings and pull information from them in a searchable form. In a video demo on Rewind.AI's site, the app opens when a user presses Command+Shift+Space. The search bar suggests typing "anything you've seen, said, or heard." It also shows a timeline at the bottom of the screen that represents previous actions in apps.

After searching for "tps reports," the video depicts a grid view of every time Rewind has encountered the phrase "tps reports" as audio or text in any app, including Zoom chats, text messages, emails, Slack conversations, and Word documents. It describes filtering the results by app -- and the ability to copy and paste from these past instances if necessary. Founded by Dan Siroker and Brett Bejcek, Rewind AI is composed of a small remote team located in various cities around the US. Portions of the company previously created Scribe, a precursor to Rewind that received some press attention in 2021. In an introductory blog post, Rewind AI co-founder Dan Siroker writes, "What if we could use technology to augment our memory the same way a hearing aid can augment our hearing?"
Rewind AI provides few details about the app's back-end technology but describes "mind-boggling compression" that can reportedly compress recording data up to 3,750 times "without a major loss of quality," giving an example of 10.5GB of data squeezed down to just 2.8MB.

      We've heard this song before. And it always turns out to be bullshit.

      Great. The malware people will add this as one more thing to look for when they compromise your computer and it will now be 3,000 times faster and easier to exfiltrate all your data. Genius.

        Nah, 10.5GB of repetitive useless XML crap easily compress into 2.8MB especially if you also use de-duplication, I assume that's what they meant. /s

      • We've heard this song before. And it always turns out to be bullshit.

        I paused when I read that line too, but I wonder if they're referring not to video capture, but to activity on your PC. If it functions somewhat like RDP versus VNC - VNC transmits large images so it's a lot of data, while RDP transmits information about the windows instead, so it's speedy and a lot less data. In a way that's sort of "compression" with no loss of quality.

        An actual recording of your Zoom call obviously wouldn't be eligible for the same level of data compression if they need to be able to r

      Those aren't mere "people" buying this solution. Or strictly governments. Those are your major employers who are chomping at the bit to collect and sell off that data.

      And there's probably not a damn thing you're going to do about it after their literal army of top-tier litigators lobby for such employer protections to be passed to make such activity not only legal, but mandated as a condition of employment.

      Bad? Wait til you hear who's likely to be the one paying for the solution via payroll fees, while corporate profits off it with "royalties" handed to the C-execs it was sold to.

      TL; DR - I'd say every company involved knows exactly who the target audience is here, and they're not standing up a charity.

      • Use your personal equipment for personal stuff. Use your work equipment for work stuff. Don't put work on your personal equipment, or personal stuff on work equipment. Carry 2 cellphones if necessary.

        Compartmentalize everything as best as you can. You don't owe your life to work, unless you choose it. Like the big fat paycheck? You might not like the real cost.

          Hi Archangel,

          As part of our routine HR audits using the new Rewind AI tool we have noted you were stationary on a single application between the following times:
          * 10:05 AM to 10:27 AM
          * 11:17 AM to 11:45 AM
          * 12:02 PM to 1:15 PM
          * 2:23 PM to 3:06 PM
          * 3:45 PM to 4:22 PM

          Please take note that, other than during your scheduled lunch break between 12:00 PM to 12:30 PM, you are expected to be actively engaged in work related activities. We would like to remind you of the clause stated in your employment acceptance agreement, of which you agreed to, stating the use of personal devices is only permitted during your scheduled lunch period unless you are able to provide adequate evidence of a developing personal emergency.

          If you were away from your desk assisting other team members during these times please submit, and review, the corroborating documentation and witness statements with your manager. Until this has been completed we will have no choice but to assume you were using this unsanctioned time for personal reasons and will be adjusting your next pay accordingly to reflect the reduced hours of work. It is important to stress that repeated instances of this behaviour will result in disciplinary action which could result in termination of employment.

          It has been our pleasure to work with you on this performance issue today, should you have any questions please reach out.

            Hi HR Professional,
            As you'll see from my employment agreement, I'm an exempt employee (ie, salaried). This means I do not work according to any regular hourly schedule -- the times of my work and the duties I perform may vary from day to day. During the times you listed, I was definitely not working. What I was doing instead, however, is quite irrelevant. If you'd like to amend the terms of my employment, so that I might in the future be subjected to this type of tyrannical hovering, please do so in writing

        it runs on Macs, business won't be buying in until they get a windoze "solution" and shortly thereafter, MS will announce CryptoSleaze, Your Friendly AI Recording Chef. Except then business will have to figure that sending all their information back to mothership is worth it...okay, so they'll sign on in a heartbeat.

    • Contrary to many privacy-concerned posters, *I* at least think this could be a good idea, in the appropriate situations.

      Of course, all of the use cases below depended on the software being reliable and secure, in the sense that we can be confident it was not sending everything back to mothership (which could be tricky but not entirely impossible, e.g. by some kind of sandboxing or by being open source).

      First off, the more obvious use cases would be in the legal field. Certain roles may benefit from having

      Of course it can. In fact, .bash_history is the very first place where hackers look for your credentials. Why? Because very often passwords, keys or paths to files where such credentials are stored are included as a part of the command. There are also times where you accidentally enter passwords of all sorts as commands, after a failed copy-paste for example, and they all get logged in .bash_history.

      It'll likely run on the GPU and could be quite lean.

      When I do QA for my own stuff, I do record myself using OBS and the NVENC of my graphics card, so I go through everything again in slow motion and pause to get a closer look at details that I might have missed otherwise when too many things to keep track of change at the same time, and where logging things into a file alone wouldn't be too helpful either (so you do both).

    Why limit this compression innovation to only spying? I'm sure everyone would love to use it for lots of other things.

    I'll have to be honest, this really sounds like middle out compression, complete with hand gestures.

    I've doing something like this myself for years. I run Linux, and have a script running every minute taking screenshots and processing them. I use ImageMagick tools to treat the files: "import" to take a screenshot, "compare" to say how much the picture changed since the last run (and stop the script if nothing changed), "convert" to make two versions: one bigger with contrast up to feed "tesseract" for OCR, and one smaller with less colors for storage.

    A few times a day I feed the text to ElasticSearch (when the load on the system is low) and I have a PHP script to search for things. So when I need something I read or saw, I can search and have both the text and the image. Tesseract results are mixed, sometimes flawless that I don't need to look at the images, sometimes is a garbled mess. I've tried AI-powered OCR, they work better, but turns my computer into an area heater.

    It uses less than 700MB per year, so I believe it's worthy. And uses only tools on my system, so even if that startup says "it never leaves your computer" you cannot say for sure that someday in the future that changes and nobody notices. It's portable too: the pictures are png, the text are plain .txt, ElasticSearch indexes can be exported (or you can import them on any other fuzzy text search). If that startup dies (or forces itself out of your system), you would lose everything you saved.

Think of it! With VLSI we can pack 100 ENIACs in 1 sq. cm.!
