Perplexity Takes Over Your Mac
PLUS: Codex Becomes Agent, Google AI Controls Ads
1/ Perplexity Rolls Out AI That Can Operate Your Mac
Perplexity AI rolled out its “Personal Computer”, a Mac-based AI that can run tasks across your files, apps, and browser locally.
Three reasons why:
Keeps data local, which is critical for privacy and enterprise adoption
It can access and act across tools like Mail, Calendar, and local files
Runs continuously in the background, not just on prompts
The real competition is no longer app vs app. It’s which AI that controls the workflow. Once AI sits above your tools, software becomes replaceable — and that’s where the power shifts.
2/ OpenAI Turns Codex Into a Full AI Developer Agent
OpenAI upgraded Codex from code suggestions to executing full development tasks.
This matters because AI is moving beyond assistance into actual output. It signals early automation of junior-level technical work.
The catch: still needs human oversight for reliability.
3/ Google Shifts Ad Enforcement to AI Filtering
Google blocked a record 8.3B ads in 2025, but suspended fewer advertisers — thanks to AI-driven filtering using Gemini.
This matters because AI is now stopping bad content before it appears, not punishing after.
The shift: from targeting bad actors → targeting bad behaviour at scale.
