mindstorm

A weekly AI podcast that mines your second brain and remixes it into an episode. Not a recap — a remix.

Every Wednesday, Mindstorm queries a personal Supabase vector store (recent memories, decisions, contradictions, semantic clusters), generates a full-length two-host dialogue via Gemini Flash, converts to audio via Gemini multi-speaker TTS, and publishes to a private RSS feed.

What it sounds like

Two hosts — Jeremy and Maya — work through whatever the second brain has been accumulating: recent decisions and their rationale, patterns across unrelated notes, contradictions between old beliefs and new ones, things that were flagged but never revisited.

Episode format rotates:

• Standard (most weeks) — 7 rotating analytical personas. The Chaos Archivist, The Pattern Spotter, The Devil's Advocate, etc. Each brings a different lens to the same material.
• The Oracle (every 12th week) — tarot spread framing. Each card position maps to a dimension of your current situation.
• Letter to Future Self (every 8th week) — one host writes aloud to the other's future self. Forces confrontation with what you're actually building toward.

Seed question: drop any question into mindstorm_seed.txt and it steers the episode. Clears after use.

Architecture

Second brain (Supabase vector store)
    → recent memories (last 14 days)
    → semantic clusters around current themes
    → random "gems" from the archive
    → flagged contradictions
          ↓
    Gemini Flash script (~9,000 words)
          ↓
    Gemini multi-speaker TTS → MP3
          ↓
    RSS feed + Telegram notification

Uses personal-podcast-engine as the audio layer.

The second brain it reads from

Mindstorm is one plugin in a broader personal AI stack built around a Supabase vector store:

• second-brain-brief — daily morning brief from the same store
• second-brain-interviewer — loads the store via structured voice interview with an AI analyst
• personal-podcast-engine — the audio pipeline this show runs on
• tubecap — Monday show: digests your YouTube/podcast watch history

The second brain accumulates through daily notes, voice memos, meeting captures, and interview sessions. Mindstorm is how it talks back.
