What are Signals?

Signals are AI-curated intelligence feeds that deliver the latest news and insights on any topic you care about. Think of them as your personal newsletter — except the AI does all the research, scoring, and summarizing for you.

How It Works

1. Browse or create a signal on a topic you care about (AI research, startup funding, tech trends, etc.)

2. Subscribe and choose how you want to receive updates — in the feed, by email, or through your favorite messenger

3. Read concise, AI-written articles with source links, quality scores, and translations in your language

Crew's AI searches the web, evaluates sources, and synthesizes the best content into easy-to-read articles — on a schedule you choose (daily, weekly, biweekly, or monthly).

Browsing Signals

Go to Signals in the sidebar (or press S) to open the main feed.
