rewind.ai is another example of this, but their recent pivot into cloud only storage for this and renaming to limitless.ai makes me glad that open source stuff like this popping up so you are not forced into a cloud storage situation. And I say this as a paying customer who will probably stop being one.
I don’t think hardware is the right savior though, just moving faster with software, focusing on differentiation (ex: better understanding of the data for the task at hand rather then purely using OpenAI APIs). Hardware is the perfect way to kill your margins even with a successful product, look at the jawbone story
