Daily Brief

A personal intelligence briefing agent — newspaper-style daily digest powered by Claude AI and live web search.

What it does

Daily Brief generates a personalised morning and evening news digest across topics you care about. Each edition includes:

Topic sections — 2–3 high-signal stories per topic with summaries and a “why it matters” line
TLDR News Roundup — automatically pulls coverage from TLDR News Global and TLDR News EU
Worth watching — 2–3 slow-burn developments to track across the week

Runs automatically at 6:00 AM and 5:00 PM NZT via a Cloudflare Worker cron. Can also be triggered on demand from the app.

Features

Toggle topics on/off — Cybersecurity, AI & ML, Geopolitics, Tech industry, Science, Markets, NZ news, AU news
Add custom topics or keywords (e.g. “threat intelligence”, “SIEM”)
Three depth settings — Headline, Standard, Deep Dive
TLDR News Global and EU integration — no copy-pasting required
Exclude topics you don’t want
Optional personal context to tailor the “why it matters” angle

Layer	Technology
Frontend	Vanilla HTML/CSS/JS — no build step
Hosting	GitHub Pages
Backend	daily-brief-worker (Cloudflare Worker)
AI	Anthropic Claude Sonnet + web search

Setup

This frontend requires the daily-brief-worker to be deployed first.

Once the Worker is live, update this line in daily-briefing-agent.html:

const WORKER_URL = 'https://daily-brief-worker.YOUR_NAME.workers.dev';

Then push to this repo and enable GitHub Pages: Settings → Pages → Deploy from branch → main → / (root)

Your app will be live at https://securityguidebook.github.io/daily-brief.

Daily Digivolve

The backend Worker exposes a GET /brief endpoint that returns the latest cached brief as JSON — including a pre-formatted summary string for the Daily Digivolve avatar to speak on startup. No changes needed to this frontend when that integration is added.

See daily-digivolve for details.

Security

All API calls go through the Cloudflare Worker — the Anthropic API key is never exposed in this frontend or stored in the browser.
