MyJunto

Curate Your Sources. Get Your Dispatch.

MyJunto lets you build a junto — a curated group of Twitter/X voices you trust — and receive a daily AI-synthesized dispatch: signal, not noise.

Named after Ben Franklin's intellectual discussion groups.

How It Works

1. Curate — Create a junto by adding Twitter/X sources you follow
2. Track — The platform builds analyst profiles for each source (stances on assets, sectors, themes)
3. Dispatch — AI synthesizes a daily newsletter from your junto's recent tweets — your lens, your signal
4. Positions — Browse the heatmap of what sources are bullish/bearish on, filtered by junto, category, or stance

Data Pipeline

pull-content (every 6h)
  └─ Loads active sources → starts Apify batch run → saves pending run ID

collect-twitter (runs ~20 min after pull-content, then every 5 min for ~25 min)
  └─ Polls Apify for results
  └─ Stores tweets → backfills avatar_url / display_name from Apify author data
  └─ Triggers Claude Haiku profile update when new tweets stored
  └─ Stale profile sweep: re-analyzes any profile not updated in 48h (3/cycle cap)

generate-newsletters (every 5 min in window after collect)
  └─ Loads pending dispatches → reads content_twitter
  └─ Claude Haiku synthesis → delivers via Resend (email) / Telegram

Analyst Profiles

Each source gets an AI-maintained analyst profile (source_analyst_profiles table):

• Summary — 1–2 sentence description of the analyst's focus and style
• Positions — Map of tickers/sectors to { stance, since, note } where stance is bullish | bearish | neutral | cautious

Profiles update whenever new tweets are collected, or via stale sweep (any profile not updated in 48h gets re-analyzed, capped at 3 per collect cycle).

Tracked position types: specific tickers (BTC, TSLA, DRO.AX), named commodities (gold, uranium), investable sectors (semiconductors, defense, AI).
