Upstream monitors Hacker News, arXiv, Twitter, and 20+ sources every hour. Every morning, you get a crisp briefing — the 5 things worth knowing, zero filler.
Every morning, one email. The five highest-signal stories from the previous 24 hours, with context on why they matter — not just what happened.
Each story gets a confidence rating based on source authority, cross-referencing, and recency. You know what's solid and what's trending noise.
Once set up, the agent monitors continuously. New sources added automatically. No writer, no editor, no subscription to manage.
Hacker News, arXiv, Twitter/X, Substack newsletters, tech blogs — 20+ sources scraped hourly by autonomous agents. No manual input.
AI evaluates each story on authority, novelty, cross-source agreement, and relevance. Stories cluster — 20 posts about the same event become one briefing item with confidence weighting.
Top 5 stories get a two-sentence summary, source links, and confidence score. Sent to your inbox at your preferred time — before the workday starts.
AI researchers, startup founders, engineers, and operators who can't afford to miss what happened — but can't afford to spend 2 hours on it either.
The agent finds it first.
