Things on our mind

Longer reads from the studio. Mostly big topics like energy, money, and privacy, explained in plain language, plus the occasional product note.

Meet ChartFlow — the stat clip, without the motion-graphics app

Eight seconds of numbers climbing on screen, bars overtaking each other, the point landing harder than any sentence could. It normally costs an afternoon and a subscription. Type your numbers, pick from nine chart types including the bar chart race, export MP4, Shorts or a transparent overlay — free, in your browser, and nothing leaves your device.

Meet ReadFlow — the article video, without the keyframe grind

An article on screen, the camera gliding across it, key phrases lighting up one by one. It's in every news breakdown on YouTube and it usually costs you an afternoon of keyframes. Paste your text, pick the phrases, tap along to your narration, export MP4 or Shorts — free, in your browser, and nothing leaves your device.

Here's the idea that could change where our fuel comes from, and why it isn't at the pump yet.

Surveillance pricing: when the price tag is about you, not the product
