Each blip the radar finds above becomes a card here. Click a blue name to follow it — in the app, just press F.

Noise to signal

Two hundred headlines a day. You read eight cards.

AI scores every article for relevance, drops the sponsored and the gossip, and merges the same story from several outlets into one card.

Sample: one topic, one day.

How it works

Three steps. Then it runs on its own.

1

Describe a topic

One sentence is enough — "Climate tech", "AI in hospitality". No keyword syntax.

2

Tick the sources

AI proposes trade media, newsletters, subreddits and YouTube channels, samples each and scores it 0–100 with a reason.

3

Read the cards

Every 30 minutes: scored, de-noised, merged — with a one-line summary, three key points and why it surfaced.

Features

From tracking to knowing, in one place.

Source judging

Sampled before scored, with a reason; hit rates tracked afterwards. Sites that block reading are flagged, never faked.

De-dup + summaries

The same story from several outlets becomes one card marked "+3 sources" — a one-line summary, three key points and why it surfaced. The original is one click away.

FAQ

Honest answers.

Something else? hello@slowradar.com

Where do sources come from? Can it read any site?

From public RSS feeds, newsletters, subreddits and YouTube channels. Some sites block automated reading; we flag those clearly rather than pretend.

How accurate are the AI scores and summaries?

Useful most of the time, but AI makes mistakes. Every card links to the original, and scores are a ranking aid, not a verdict.

Is it for teams?

Not today. Slow Radar is built for individuals; your topics and library are yours alone.

How good is the Chinese support?

The interface and AI summaries are available in Chinese; original headlines and proper nouns stay in English so sources stay traceable.

What stage is it at? Can I export my data?

It's in beta, so features and pricing may change. You can export your library at any time and cancel whenever you like.
