A native Mac app as a modern tmux replacement. I manage agents and terminal sessions across several GPU machines and having it all in one UI has been great for reducing cognitive load. If anyone's interested in being an early adopter

I would also describe haventerminal.com as making tmux pretty and usable! but without any setup steps, first class support for agents, and management of multiple machines. Disclaimer: It's a macOS app we just launched and it ships i

Over the weekend I built a website for teachers and parents to ask questions from Maria Montessori but couldn't fit all the relevant docs into context windows. The other RAG libraries were either doing too much (IMO) or involved conne

Thanks for this feedback! We're rolling out an update soon that will allow you to hear your translated voice without joining a call. CPU usage is on the radar, hope to make some progress there soon as well.

Yes, we're planning a Windows launch as well! If you need something today, we also have our own video conferencing platform with AI interpretation built in that works in-browser. It's at https://startpinch.com/me

Our first focus is desktop, but we'd love to get a mobile app out (or let someone else build one with our API)

Yes, if you're watching TV on your computer the app should translate all the speech. We haven't done any source separation work (musical singing vs actual speech) so if there's music it may pick up some of the lyrics.

Yes, right now we're ranging from 0.75-3 seconds for the translation to start, and we're hoping to move the average time lower with our next updates. There will always be some limitation to how fast we can translate (different la

We're hoping companies with international teams will switch over fully (we have internally), but our initial goal is to attract a subset of the market that has cross-lingual needs and unblock them as much as possible from using it more

Fantastic question. Our opinion on this is that the higher-bandwidth we can make the communication, the more useful it will be. The reason we've moved from IRC->VoIP->Video is because of the efficiency of information transfer a

Thanks, there are certainly a lot of fun and challenging problems to take on in the space. On scaling, the agent architecture isn't limited to one machine, so you can also autoscale your machines. It's essentially python's

It's hard, don't do it :D We have a few supply chain companies trying us out though! Would love to hear more about your experience.
