Daily Briefings

From Reactive to Proactive

Search is powerful, but it's reactive — you have to know what to look for. A daily briefing flips the model: your second brain tells *you* what's important.

Think of it like a personal research assistant who reads everything you captured yesterday and gives you a morning summary: "Here are the three themes from your recent notes, two action items from meetings, and a connection you might have missed."

What Makes a Good Briefing

A briefing should be scannable — you read it in 60 seconds over coffee. It's not a dump of everything that happened. It's a curated summary.

Recency Filtering

The briefing starts by selecting what's new. A simple date filter works:

function getRecentItems(documents: Document[], days: number = 1): Document[] {
  const cutoff = new Date();
  cutoff.setDate(cutoff.getDate() - days);
  return documents.filter(doc => new Date(doc.createdAt) >= cutoff);
}

Configurable windows serve different needs:

Topic Grouping

Raw chronological lists aren't useful. Grouping by topic reveals patterns:

Tag-based grouping is fast and predictable. Semantic clustering catches connections you didn't tag. Use both.

Action Item Extraction

Meeting notes and project docs often contain buried action items. Extraction patterns to look for:

Extracted action items get surfaced as a separate checklist in the briefing — not buried inside summaries.

Generating the Summary

The summarizer takes grouped items and produces natural language:

## Your Daily Briefing — March 15, 2025

**5 new items** across 2 themes

### Theme: API Architecture (3 items)
You saved a bookmark on REST vs GraphQL trade-offs, wrote a note about
rate limiting strategies, and captured meeting notes where the team
discussed migrating to gRPC. The consensus was to prototype gRPC for
internal services while keeping REST for public APIs.

### Theme: Hiring (2 items)
Two new project doc updates on the engineering hiring pipeline.
The senior backend role has 3 final candidates. Decision expected by Friday.

### Action Items
- [ ] Send gRPC prototype scope to Alex (from team sync meeting)
- [ ] Review backend candidate take-home submissions (due Thursday)

Briefing as a Habit

The technical implementation matters, but the real value comes from using it daily. The best second brain systems build a habit loop: capture throughout the day, briefing in the morning. Each briefing reinforces the value of capturing, which feeds the next briefing.
