The Gemini Notebook Master Sheet — Every Feature of Google’s Free Research App (ex-NotebookLM), the One Move That Unlocks Each, Every Limit That Matters, and the 15-Minute Learn-Anything Loop

The companion to the full course video. NotebookLM was renamed Gemini Notebook in July 2026 — 30M+ people use it, and most use about ten percent of it. We ran every single feature live on one giant demo notebook (Stanford's 2026 AI Index report) and turned the whole thing into a 6-page operating manual. INSIDE: (1) THE MENTAL MODEL — the whole app in one sentence (Sources · Chat · Studio) so nothing ever feels complicated again, plus the source cheat sheet: PDFs, Docs, Slides, websites, copied text, even YouTube links, with the real limits (Free: 100 notebooks, 50 sources each, ~500K words per source · Pro: 300 sources) and the Fast Research move that fills an empty notebook with ten vetted web sources in thirty seconds. (2) CHAT THAT CAN'T WANDER — why grounded chat with citation chips is the anti-hallucination playbook, the 1M-token context, saved history, and custom roles. (3) THE PODCAST CONTROL ROOM — all four Audio Overview formats (Deep Dive, Brief, Critique, Debate), lengths, languages, the focus prompt that steers the episode, and Interactive mode: tap Join and interrupt the AI hosts with your voice, mid-episode. (4) EVERY STUDIO BUILDER with 'the move' for each — Video Overviews (Short / Explainer / the new Cinematic), Mind Maps, the Reports document factory (including the AI-suggested custom formats), Flashcards with difficulty + mastery tracking, the self-explaining Quiz, Data Tables, Infographics and Slide Decks. (5) DEEP RESEARCH — the agentic researcher that planned a multi-step run, browsed the web, and delivered a multi-page report citing 63 sources (WEF, IMF, university labs) that imported into our notebook in one click, taking it from 10 to 74 sources. (6) THE 15-MINUTE LEARN-ANYTHING LOOP — the four-step routine that turns any topic into a personal university at zero dollars — plus six copy-paste steering prompts, the full Free-vs-Pro daily-caps table (3 audio + 3 video generations a day and 10 Deep Research runs a month on Free, as of Aug 2026), and the honest fine print on what's still Ultra-only.
