Track changing views

Goal: understand how thinking on a debate evolves.

Every insight is stamped with the moment it was said (published_at — the episode’s air date), so the corpus supports point-in-time comparison. Run the same Search over two windows:

1{
2 "query": "NVIDIA competitive exposure to hyperscaler custom ASICs",
3 "tickers": ["NVDA"],
4 "date_from": "2026-03-01",
5 "date_to": "2026-05-31"
6}
1{
2 "query": "NVIDIA competitive exposure to hyperscaler custom ASICs",
3 "tickers": ["NVDA"],
4 "date_from": "2026-06-01"
5}

Or let Ask do the comparison — it reads a time window from the question:

1{"query": "How have investor views on NVIDIA's ASIC exposure changed since June?", "answer": true}

Look for: arguments that appear in the recent window but not the earlier one, arguments that disappear, sentiment shifting on the same mention, and new speakers entering the debate.
