The AI tools worth your time. One email a week.

The tools, reads, and big-lab releases that actually matter. Each gets a one-line verdict from an engineer who ships.

What you'll get — straight from issue #18

Star of the week

Sphinx coding open source

A git pre-push hook: a reviewer model that never saw your chat quizzes you on the diff before your agent's code ships.

252 points on HN, the same week an Ask HN on shipping AI code you don't understand hit 606. Your answers never reach the agent.

Alter agents freemium

A credential vault and proxy for agents: the agent never holds the key, and sensitive calls wait for a named person.

63 points on Launch HN, but this week's lesson as a product: a key the agent never sees can't leak from its logs.

Llmspeed local-ai open source

Pick a GPU or Mac and a model, and it plays tokens back at the speed you'd actually get.

329 points on HN. Feel the speed before you buy the hardware; some figures are projected from specs, so treat them as estimates.

Earshot audio open source

Gives coding agents ears: it describes and scores sounds, reviews a film's audio, and makes sound effects in code, on CPU, over MCP.

2,083 stars since October 15. Agents can already render a demo video; now they can hear whether the click lands on the cut.

Skip the scroll. Keep the signal.

I read the launches, changelogs, and hype threads so you don't have to — and send only what survives the filter. Curated by @aimorsels.
