It's useful to me in that you've identified an interesting niche! I like the idea! As for the implementation, eh, I'd probably rather code my own so it can be in bash or c++ ;-)

It's also useful to me in that it's a solid example of what can be done with LLMs these days, wow!

Also, tangentially, a long long time ago I had a similar system set up, except for packets, not screencaps or audio. A 24h ringbuffer on my router to log _everything_ was a cool-to-have that made debugging network issues easier.

capturing and uploading a whole new PNG for each screencap is not what I would call 'efficient', and to meet the use case of Rewind.ai in the first place it should have some OCR mechanism to pull up the relevant screencaps.

PNG per frame? Ouch.

If I was to build one of these, which I'm not, I would try for a RTSP to bucket uploader. That way you could do the actual capture and compression with OBS like any other streamer - or use it with IP security cameras etc. You'd probably end up with a pile of video-ts pieces which could be replayed later using HLS.

Earlier quoted context omitted.

ffmpeg works well, especially on apple silicon using video toolbox. That's how I approached it. Also, automatically doesn't cost storage for identical screenshots (no activity) and very cheap for just moving your mouse around or typing a few characters.

rem looks very intriguing, I'll give it a try, cross platform would be even better ofc. You're doing it without funding? I wish the LLMs were tuned into the open source landscape more, so when someone has an idea for a POC and asks the bot to write it for them, it would go clippy mode and say "it looks like you're trying to build an open source rewrite of Rewind, would you like to clone the rem repo and contribute to…

No funding- I built mostly over 2023-2024 holidays and then a little here and there.

And yeah- lots of similar projects and/or possible startups have popped up as well

I know right :') Not very efficient yet.

I've also explored Swift AVFoundation to drop frames and colours at the moment of recording, but won't be implementing it at this time.

This was just a POC, and couldn't hack it in a day.

Nice! This is needed as it seems rewind.ai still stores locally but limitless the product they seem to put more energy into goes to the cloud.

I really like the rewind.ai retrieval mechanism. I believe their recording mechanism is highly broken. It often fails to sync to the os calendar and will ask you to record meetings you deleted months ago.

I don’t understand the webcam recording need. I’m not sure what signal you get from that since if you are in a web meeting you already have that on screen. Or if you are coding you might get a few WTF frown faces if working on a hard bug. But you made it optional, so that’s good.

Thank you all so much for chming in about rewind. I’ve been ruminating about what to do about my subscription. To see that I’m not alone in paying for this app that the founder ditched… I finally feel heard. Thank you!

While we’re here, has anyone been able to export audio from Rewind.ai’s local storage?

Based on the repository description: > Attempt to create an Open Source Privacy Focused Rewind.ai Alternative for data capture I'd assume this was something local or at least for your local network. But this exclusively sends the data over to S3. And based on the lack of encryption keys or even passwords, I'm assuming this is even unecrypted?

I believe the S3 bit is just as an object storage standard

I pay for Rewind, and honestly, it’s one of the best investments I've made in software. After each Zoom meeting, I receive a summary of everything discussed, including action items to add to my to-do list. Every Monday, I also ask it to remind me of what I accomplished the previous week to help me prepare for my 1:1 meeting. Everything is recorded locally, allowing me to search for anything I did earlier in the day quickly.
