AI Is Making HTML a Practical Replacement for PowerPoint on Client Deliverables

A year ago, asking an AI to generate a client-facing proposal as HTML instead of a Word doc or PowerPoint deck was an interesting experiment with an obvious catch: the output looked like a developer built a slide deck at midnight. Design was generic, PDF export was messy, and handing a client an HTML file felt unprofessional enough to undermine the whole thing.

How to Use AI Tools Like a Power User, Not a Beginner

There's a growing gap in most workplaces between people who use AI and people who work in AI. The first group opens ChatGPT, types a question, copies the answer, and moves on.

Users Report Claude Inserting Unexplained Injection Prompts Mid-Conversation

Some Claude users have noticed unexpected text appearing at the end of the AI's responses - text that reads like a system-level instruction rather than a natural reply. What they're seeing is what security researchers call a "prompt injection": an instruction embedded in text that can redirect an AI's behavior. The strange part is that the injections appear to be coming from Claude itself, not from any external content trying to manipulate it.
