Solid hands its agents their own computers, their own accounts and a budget to spend, which sounds mad until Trevor explains why. Agents can already do the simple jobs; the moment one needs a server or a login or a way to pay, it stops and waits for a human, knowing exactly what to do next and having no means to do it. So Solid's agents set up real machines, open accounts, pay for services, and use your tools through APIs or by logging in like a person would. His team raised $6M on that idea, and asked whether the output is handoff-ready he pointed at users running 300,000-line codebases, which only holds together if the architecture underneath is clean.

ToneBird drafts your replies in Gmail and Slack with the thing every other assistant misses, which is that your boss and your best friend and your landlord all get different sentences from you. It reads the conversation history and what it knows about the person, so it won't open a message to your teammate with "I hope this message finds you well" and won't reply to a client with "lol ok babe", both of which are Piper's examples from the launch. It also remembers the thing you casually promised last week, which you have forgotten and they have not. Nothing sends without you pressing the button.

Lightmeter does two jobs. It meters light for the film camera you're already carrying, with push and pull and spot readings, and when you haven't got one on you it takes the photo itself. Aakash shoots film and had got tired of either carrying a separate meter or trusting a number off a phone app, so he built the one he wanted. Then he worked out what had always bothered him about film-camera apps: they take a finished, flattened phone photo and paint grain on top, which is why they read as a filter. His works off the raw capture, so the grain and the halation come out of the image itself. No AI, no account, nothing leaves the phone.
