Daily field log

Ten things worth reading.
Every morning. Nothing more.

Pulse is a personalized research digest for people who follow ideas seriously. Tell it what you care about — it reads Hacker News, Reddit, ArXiv, and the broader web overnight, filters the noise, and delivers exactly ten entries tailored to you.

— Not a feed. Not a newsletter. A daily log of what moved in your field.

How it works

Three steps. No configuration.

01

Tell Pulse what you follow

Write in plain English. Topics, papers, communities, companies — anything you want to track. No categories to pick from, no checkboxes.

02

Pulse reads the web overnight

Crawls Hacker News, Reddit, ArXiv, RSS feeds, and Google News. Each article is scored for relevance to your exact profile. Noise is dropped.

03

Ten entries arrive each morning

Every entry has a three-sentence summary and one line explaining why it matters to you specifically. Your inbox, not an algorithm's feed.

This is what your morning log looks like. Entries, summaries, and a margin note explaining why each one matters to you.

Anthropic releases interpretability findings on chain-of-thought faithfulness

Researchers found that models sometimes reason correctly in scratchpads while producing outputs inconsistent with that reasoning — raising questions about whether visible reasoning is the actual decision process.

Directly relevant to your interest in AI safety tooling — the gap between stated and actual reasoning is the core problem you have been tracking.

LangGraph 0.3 ships persistent memory across graph runs without external stores

The new in-process memory layer lets long-running agents maintain state across interruptions without Redis or a vector DB. Early benchmarks show 40% reduction in round-trip latency for multi-step pipelines.

This lands exactly on the architecture problem you described — worth reading the migration guide before your next sprint.

Y Combinator W26 batch: 18 of 240 companies are infrastructure plays for AI agents

The proportion of agent-infrastructure companies in the batch has doubled since S25. Most are targeting the orchestration and observability layer rather than foundation models.

The segment you follow is now 7.5% of YC's intake — the market signal you were watching for is here.
