Quick Hits

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.

Pro Tip

GPT-4o voice mode can play a specific buyer persona and respond to your research questions with consistent, persona-appropriate pushback. This is not a replacement for real customer conversations.

Productivity Gem

The traditional executive onboarding reading list is 200-400 pages of documents that take days to absorb. The documents are essential. The days are not available.
