I Replaced My $700/Hour Coach with NotebookLM – Here’s What Happened

AI can function as a highly effective “context coach” when it’s fed a large, personal knowledge base—delivering fast, specific pattern recognition and actionable self-reflection—while still falling short on the emotional, relational read that skilled human coaching provides.

The core test centers on Tiago Forte loading NotebookLM Plus with roughly 40 documents totaling nearly 150,000 words of his own work and life context. The materials are organized into three buckets: private notes (including coaching-session notes, a yearly life-goals mind map, Big Five traits, a time-perspective framework from Zambardo, strengths compiled from customer testimonials, gratitude lists, and a Myers-Briggs profile), public writing (course takeaways, Burning Man experiences, book summaries, autobiographical writing, and open questions), and annual year-end reviews spanning the last five years. After about 17 minutes of source setup, he runs a set of coaching-style prompts—many drawn from prior AI conversations—to see whether the system can do more than summarize.

Early outputs focus on strengths and weaknesses. Strengths are described in broad, recognizable terms—knowledgeable, visionary, creative, innovative, insightful, and perspective-shifting. Weaknesses are more granular and feel psychologically “on target,” including self-criticism and perfectionism, sensitivity to criticism and conflict, idealism that can overlook details, perceived social-skill challenges, emotional vulnerability and resistance to emotional processing, and tendencies toward being overly private. He’s particularly struck by the thoroughness and the way the weaknesses align with his Myers-Briggs type (INFJ), which makes the feedback feel less generic.

The more consequential section comes when NotebookLM is asked to identify contradictions between stated intentions and actual behavior. The system highlights a recurring tension: he frequently signals work-life balance in annual reviews, yet his actions and results prioritize business growth and achievement, often at the expense of personal time and well-being. It also flags control issues that complicate delegation, a push-pull between financial prudence and free spending (including a reaction against his father’s frugality), and a cycle of chasing novelty (“shiny objects”) alongside burnout and distraction from family life. The output frames these as persistent themes rather than isolated mistakes.

When asked for blind spots and limiting beliefs, the AI surfaces second-order insights—such as avoiding disappointment, which paradoxically can intensify disappointment. It then pivots to future-oriented coaching: what he might regret at life’s end (overemphasizing work and external achievements over meaningful relationships and balance) and what best advice he should follow (prioritize self-knowledge and authenticity, integrate emotional intelligence, move toward integration rather than compartmentalization, value relationships and community, embrace vulnerability, define “enough,” and prioritize balance).

The most novel and practical moment arrives with a question he didn’t previously ask: which physical sensations might be signaling unacknowledged goals, challenges, or desires. The AI links specific bodily experiences—tightness, racing heart, heavy chest, warmth/expansion, breathing changes, recurring aches—to emotional states and recommends a practice called active body awareness: pausing during the day to notice sensations without judgment and using targeted questions to explore what they mean.

In the closing assessment, NotebookLM’s advantage is speed and depth of recall: it can jump from big-picture patterns to fine-grained details from any sentence in his notes. Its limitation is emotional nuance—especially micro-expressions, body language, and subtle reactions that a human coach detects in real time. The takeaway is not replacement but complementarity: AI as a powerful adjunct for context, patterning, and structured reflection, paired with human coaching for relational and intuitive emotional reading.
