The full lesson text follows. ## Who this is for - Founders - Creators - Marketing teams - Agencies ## Limitations and boundaries - Course material describes the product and the platforms at the time of writing; verify current behaviour in the app. - Social network features, limits, and algorithms change independently of Bolta. - Current prices and plan limits must be verified on the Bolta pricing page. ![Banner](/images/university/courses/voice-dna-brand-agents/6.png "Cover") ## Lesson 1: How Persona and Voice Interact Voice is mechanics. Persona is identity. The agent uses both at the same time — voice tells it *how* to write, persona tells it *what kind of writer* is doing the writing. ### A simple way to picture it Imagine giving a writing sample to two different writers: - Writer A: a sharp founder who's been building for 10 years. - Writer B: a junior marketer who's been building for 6 months. If you handed both writers the same Voice DNA constraints (vocabulary, sentence structure, tone signals), they'd produce different posts. Voice constrains the *shape*. Persona shapes the *substance* and *direction*. In Bolta, both layers run simultaneously. Voice keeps the post sounding like you. Persona keeps it pointed at the right topics, tone, and worldview. ### When they conflict Sometimes voice and persona pull in different directions. Voice says "first person, casual, fragments." Persona says "authoritative thought-leader." The agent will produce something half-cooked. The fix: align them deliberately. If your voice is casual, your persona should describe a *casual* expert, not a formal one. ## Lesson 2: Refining Each Block Each of the five persona blocks deserves different attention. ### PERSONALITY — refine slowly This is the slowest-changing block. Your personality doesn't shift week to week. Refine when: - You've genuinely changed roles (e.g., from indie hacker to VC-backed founder). - The personality you wrote turned out to be aspirational rather than real. - Output keeps drifting toward a personality that isn't quite you. **Refinement style:** small clarifications, not rewrites. "Sharp founder" → "Sharp, slightly self-deprecating founder who's allergic to corporate-speak." ### TONE — refine often Tone is the most-frequently refined block because it's the most-often slightly wrong. Refine when: - Posts feel right voice but wrong vibe. - The agent is too formal or too casual relative to your taste. - A specific tone signal (e.g., emojis) is appearing where you don't want it. **Refinement style:** specific. "Be direct" is too vague. "Be direct, but never cold — leave warmth in even short posts" is usable. ### STYLE — refine when you spot patterns Style is mechanical, so it shifts visibly when something's off: - All posts are the same length. - All posts use the same hook structure. - Lists keep appearing where you'd write paragraphs. **Refinement style:** prescriptive. "Vary post length — some 50 words, some 200, never every post the same." Specifics make it stick. ### AVOID — refine carefully The AVOID block is tempting to overload. Resist. Every "avoid" item is friction; the agent is balancing all of them simultaneously. Refine when: - A specific phrase or pattern keeps appearing that you hate. - A topic the agent shouldn't touch keeps surfacing. **Refinement style:** keep AVOID under 7 items. If you're adding the 8th, ask whether something can be removed or merged. ### MINDSET — refine rarely MINDSET is the deepest layer. It shapes which topics, hooks, and stances the agent gravitates toward. Refine when: - The agent's content priorities don't match your strategic priorities. - The "why" behind posts has drifted (e.g., from helping → selling). **Refinement style:** reflective. "Why am I posting at all? What do I want readers to walk away with?" Answer that, and MINDSET writes itself. ## Lesson 3: When Refinement Becomes Rewrite Most persona problems are fixable with surgical edits. Some aren't. ### Signs you need a full rewrite 1. You've been editing the persona every week for a month and it still doesn't feel right. 2. You've changed business model, audience, or platform focus dramatically. 3. The persona was AI-generated and you never seriously edited it. 4. Your three best posts have nothing in common with the persona's apparent intent. ### How to rewrite without losing learnings 1. **Don't delete the old persona.** Save it as a comment or backup. 2. **Rewrite from scratch.** Don't try to "fix" the old one — you'll inherit its biases. 3. **Keep voice profile separate.** Voice DNA isn't tied to persona; you don't need to retrain voice when you rewrite a persona. 4. **Run on Manual or Assisted for 7 days** after a rewrite. Watch closely. ### The over-refinement trap Some founders refine personas weekly. Don't. Each refinement is a signal change to the agent. Too many signal changes and the agent never stabilizes. Output stays inconsistent. A rule of thumb: at most one persona edit per week per agent. More than that and you're micromanaging instead of directing. ### Common myths 1. *"A long persona is a strong persona."* No — a focused persona is a strong persona. Aim for one screen. 2. *"Refining persona will fix performance."* Sometimes. Often, performance issues are about job instructions, schedule, or platform fit — not persona. 3. *"AI-generated personas are good enough."* They're a starting point. Your refinements are what make the agent yours. ### Action Steps 1. Open one of your agents. Read each of the five persona blocks. Score them 1-5 for clarity and specificity. 2. Pick the lowest-scoring block. Refine it surgically — one edit, focused. 3. Watch the next 5 outputs. Did the refinement show up? Adjust if needed. A persona is a piece of writing that other AI uses to write more writing. Treat it with the care that implies. Next lesson: editing as training — why how you edit matters more than what you write. ## Relevant links - [Bolta University](https://bolta.ai/university) - [Voice DNA & Brand Agents](https://bolta.ai/university/courses/voice-dna-brand-agents) - [Bolta pricing](https://bolta.ai/pricing)
