youtube often blocks servers (that's the one thing the paid tools pay for). the free way:
open the video → description → "show transcript" → select all → copy → paste below.
transcribed in your browser — nothing is uploaded.
creators pay $399/yr for canvas tools where the prompt is hidden. this is the engineer's version: you see the exact document the model receives, and every output comes back with a receipt — which cards it used, which it ignored, and what it had to guess because nobody told it.
that's the whole method: a good agent brief is a spec — role, context, constraints, done-looks-like. you've been writing specs for years. this board just makes the invisible part visible.
honest limits: outputs are copy-out only (no auto-posting). the receipt is the model's own account — self-reported, which is itself worth knowing. your board lives in your browser only — export it to a file if you care about it. the only thing ever sent to the model is the document you can read before you hit run.
