Top AI Updates
1. GPT-4o Voice Mode: The AI Phone Call That Replaces Your Research Assistant
ChatGPT always had a voice mode. The new one is different. The previous voice mode transcribed your speech, sent text to GPT-4, and then read the response back with a text-to-speech voice. GPT-4o processes audio natively.
2. Google NotebookLM Audio Overview: Turn Any Document into an AI Podcast Briefing
NotebookLM now generates audio. Upload a document and click "Audio Overview." Within two minutes, you have a 10-15 minute podcast-style conversation between two AI hosts discussing the key themes, findings, and implications of the document. You can listen on your commute.
3. Copilot+ PC Recall Feature: AI That Remembers Everything You've Seen on Your Screen
The Recall feature on Copilot+ PCs indexes everything that appears on your screen. Every webpage, every document, every spreadsheet, every email. The index is stored locally, processed by the on-device NPU, and searchable by natural language.
