Channel Coach
YouTube Coaching Knowledge Engine
Scrapes and synthesizes long-form video content from selected YouTube channels into actionable coaching playbooks, so coaches stay current without watching every episode.
01 — The Problem
Coaches and advisors need to stay current on the ideas, frameworks, and tactics promoted by the experts they follow — but watching every podcast, interview, and YouTube video is time-prohibitive. The knowledge lives in hours of video, scattered, unorganized, and hard to act on. Coaches either fall behind or spend more time consuming than coaching.
02 — What the AI Does
Monitors YouTube channels (Dan Martell, Joe Hudson, and others) on a 12-hour cron cycle. For each new episode over 2 minutes, extracts the transcript via yt-dlp, embeds the text for semantic search, generates a structured analysis (key insights, TL;DR, topics, venture relevance, action items), and writes the result to a knowledge base. Synthesizes individual episode analyses into cumulative channel playbooks. Sends Slack notifications to designated channels when new episodes are processed. Built on: yt-dlp (transcription), Python with SQLite (episode tracking), embeddings API (semantic search), Slack API (notifications).
03 — Design Decisions
120-second minimum duration filter (Shorts excluded)
Shorts are not representatively distinct from channel positioning and would flood the database with low-value content.
Only episodes 2+ minutes are processed. This is enforced in monitor.py.
12-hour poll interval with anchor offset
Balances currency against API rate limits. 6-hour offset from LinkedIn cron means the machine's token budget is distributed across the day.
Max 1 retry on 429 errors — no aggressive retry loops that could consume token budget.
Per-channel Slack routing
Each channel is tied to a specific Slack channel (#coach-dan-martell, #coach-joe-hudson) so the right coaches see relevant content.
Slack notifications only fire if new episodes were actually captured and analyzed.
Cumulative playbook synthesis
Individual episode analysis is useful but insufficient — coaches want the evolved position of an expert, not a collection of hot takes. Synthesis builds a coherent picture over time.
Synthesis runs only after episode analysis, as a separate step, to avoid synthesis without data.
Notion as the primary structured database, filesystem as the knowledge base
Notion provides a UI Brett can interact with directly; the filesystem provides durable markdown that survives any single tool.
Notion stores schema (URL, Status, Channel, Duration, Topics, Ventures, TL;DR, Tags); filesystem stores the full analysis.
05 — Key Insight
The value of a coaching knowledge engine compounds over time — but only if the curator explicitly designs what gets excluded as aggressively as what gets included. Curation discipline (minimum duration, 12-hour cadence, single-topic channels) prevents the knowledge base from becoming a graveyard of shallow episode summaries.
