Weekly briefing — AI search and research tools, 29 Apr – 6 May

1. ChatGPT Deep Research extended to 30-minute runs with export (OpenAI release notes, 2 May) — Why: your "research faster" lesson shows a 5-minute run; the screenshots are stale. Do: re-capture by Friday.
2. Perplexity Spaces adds shared instructions for teams (Perplexity blog, 30 Apr) — Why: your team-research module assumes personal Spaces. Do: a one-paragraph update.
3. Google AI Mode expands to 12 countries incl. DE and ES (Google blog, 1 May) — Why: 40% of your traffic is DE/ES; organic click-through will move. Do: watch Search Console for two weeks.
4. Anthropic raises Claude file limits (Anthropic docs, 3 May) — Why: your "upload 400 pages" lesson can cite a bigger number. Do: nothing yet.
5. Perplexity reported raising at $18B (The Information, 5 May) — unverified, single source — affects nothing you ship.

Safe to ignore: the "AI search is dead" essay — opinion, no data.
Quiet item: AI Mode ad formats mentioned in a Google developer note (4 May) — if ads enter AI answers, your CAC assumptions change in Q3.

Edited draft

AI lessons that take 15 minutes a day. Used by 12,000 professionals in 40 countries. Start your free 5-day trial.

Change log
- "a revolutionary AI-powered learning experience" → "AI lessons that take 15 minutes a day" — "revolutionary" is a tell; 15 minutes is a number the reader can picture
- "empowering professionals worldwide to thrive" → "used by 12,000 professionals in 40 countries" — abstraction replaced with proof
- "Begin your transformative journey today" → "Start your free 5-day trial" — the actual offer is more persuasive than the metaphor
- cut "seamlessly", "cutting-edge", "unlock" — adjectives with no referent
- "trusted by teams" → [NEEDS NUMBER] — kept, but it needs a count or a name

Weakest remaining line: "40 countries" is impressive only if the reader is outside the US; consider replacing with a named company.
