Panic button for Macs

gm legends, happy Monday.

NothingHere is a one-key panic button for your screen, Voca is trying to be the project manager quietly keeping up in the background, and Mosaic wants to automate the repetitive parts of video editing so you can stop doing the same cuts by hand every week.

NothingHere is a macOS panic button for the exact moment you need your screen to look normal fast. Hit one hotkey and it hides every window, mutes all sound, and opens a pre-picked cover document in one shot. It also has a Guard Mode in the menu bar, and it is free, open source, and tiny.

🔥 Our Take: This is extremely dumb in a way I deeply respect. It knows exactly what it is, does the one job fast, and does not pretend to be more clever than that. Also, turning the notch-era Mac into a machine with an actual panic button is kind of hilarious.

Victoria Wu from Happycapy posted after Perplexity’s launch to make one simple point: if multiple teams are independently building the same kind of agent-native computer, this is probably bigger than one product launch. She says Happycapy shipped its version back in February, and the overlap with Perplexity’s vision feels more validating than threatening.

Her bigger argument is that agents need their own always-on environment, should not be tied to one model, and that people are heading toward telling computers what they want instead of managing a pile of apps. It is a short thread, but it tees up a useful question for anyone building in this space: what actually happens when the computer becomes the agent layer.

Voca AI connects to the tools teams already use, starting with Slack, GitHub, and Linear, and keeps a live project knowledge base updated as work happens. You can ask what changed, what is blocked, or what is still open, and set up skills or automations that keep running in the background. It is still early and being piloted with a small group of companies.

🔥 Our Take: Teams are weirdly good at losing the plot. A decision gets made in Slack, code lands in GitHub, the Linear ticket gets half-updated if you are lucky, and by the next standup everyone is reconstructing the week from scraps. The appeal here is pretty obvious: something quietly keeping score without asking people to become radically more organized. 

Mosaic is a node based workspace for automating video editing. You can set up workflows for things like rough cuts, captions, b-roll, reframing, motion graphics, and exports on a visual canvas, then reuse them as templates or trigger them through an API. When you want to finish by hand, you can send the timeline back to tools like Premiere Pro, Final Cut, or DaVinci Resolve.

🔥 Our Take: Calling it Zapier for video editing is a pretty bold pitch, but it gets the point across fast. If you are still doing the same social edits by hand every week, that starts to look a bit self inflicted. Build the flow once, reuse it, and keep your energy for the parts that actually need taste.
