Generic, one-size-fits-all artificial intelligence models fail when applied to specialized, high-stakes professional conversations.

A venture capital pitch requires aggressive valuation defense and rapid unit-economics recall. A court deposition demands rigorous statutory citations and evasion detection. A clinical medical consultation requires strict SBAR communication protocols. Using a generic chatbot in these scenarios yields bland, robotic, and unhelpful responses.

Stealthify’s Custom Persona Engine empowers you to architect bespoke, real-time AI wingmen tailored to your exact industry, conversational goals, and personal communication style.

In less than two minutes, you can configure when the AI intervenes, which strategic frameworks it enforces, how it formats talking points on your invisible teleprompter, and what custom knowledge it references—all with zero coding required.

The Three Pillars of Real-Time Persona Engineering

Stealthify gives you three powerful configuration layers to craft your ideal real-time AI assistant:

+-----------------------------------------------------------------------------------+
|                        THE 3 PILLARS OF A CUSTOM COPILOT                          |
+-----------------------------------------------------------------------------------+
| 1. Trigger & Silence Rules | Precise keywords that trigger assistance vs. safe    |
|                            | zones where AI stays quiet (small talk, laughter).   |
+----------------------------+------------------------------------------------------+
| 2. Strategic Guidelines    | Core objective, decision trees, professional         |
|                            | frameworks (MEDDPICC, STAR, SBAR, Legal, VC Pitch).  |
+----------------------------+------------------------------------------------------+
| 3. Teleprompter Delivery   | Tone calibration, response format (Verbatim Script,  |
|                            | Bullet Points, Glanceable Keywords), and forbidden   |
|                            | words.                                               |
+-----------------------------------------------------------------------------------+

Pillar 1: Trigger & Silence Rules (When to Intervene)

The secret to a seamless copilot is knowing when to help and when to stay silent.

  • Respond Triggers: Specify exact phrases, topics, or emotional cues that prompt the AI to generate immediate talking points (e.g., "pricing pushback", "valuation question", "user hesitating", "technical contradiction").
  • Silence Triggers: Define conversational safe zones where the AI intentionally holds back suggestions to prevent cognitive clutter (e.g., "small talk", "client venting", "casual intro", "team celebrating").
  • Proactivity Tuning:
    • Low: Intervenes only during explicit questions or prolonged verbal hesitation.
    • Medium: Balanced pacing for standard collaborative meetings.
    • High: Continuous, sub-second ambient assistance for intense negotiations and technical interviews.

Pillar 2: Strategic Guidelines (How to Think & Reason)

Define your copilot's singular mission and decision-making logic:

  • Core Objective: Establish the agent’s primary mandate ("Act as a ruthless M&A deal strategist focused on defending contract terms and liability limits").
  • Strategic Guidelines: Outline exact multi-step frameworks, conversational pivots, and mid-flight rescue rules ("If the client pushes for unlimited indemnity, immediately cite clause 14.2 and suggest a reciprocal 12-month cap").
  • Knowledge Focus: Pinpoint which uploaded documents, case studies, or slide decks the AI must prioritize during live queries.

Pillar 3: Teleprompter Delivery & Response Styling (How it Appears)

Customize how the AI presents information on your screen-share-invisible overlay:

  • Tone: Calibrate the persona’s voice (e.g., Authoritative and calm, Witty and conversational, Socratic and supportive).
  • Response Styles:
    • Verbatim Script: Delivers complete, natural first-person sentences designed to be spoken aloud word-for-word without translation.
    • Bullet Points: Provides 2 to 3 structured, high-impact bullet points for rapid reading.
    • Glanceable Keywords: Delivers ultra-compact 1-to-3 word conceptual cues for effortless eye-line scanning.
  • Forbidden Phrases: Blacklist weak, apologetic, or non-compliant words you never want suggested on your screen (e.g., ["I think", "maybe", "discount", "sorry", "sort of"]).

Four Plug-and-Play Custom Persona Blueprints

To demonstrate the versatility of the Persona Engine, here are four battle-tested blueprints you can import directly into Stealthify:

Blueprint 1: The Startup Founder & VC Pitch Copilot

  • Target Use Case: Seed to Series B investor pitch meetings and partner grillings.
  • Respond Triggers: "valuation pushback", "TAM inquiry", "customer churn", "CAC payback", "competitor moat".
  • Silence Triggers: "partner introducing fund", "general banter".
  • Strategic Guidelines: Always anchor answers in exponential unit economics and proprietary moat defensibility. If an investor asks about churn, reframe around net revenue retention (NRR) and enterprise expansion.
  • Forbidden Phrases: ["we hope", "in theory", "we might", "burn is high"].

Blueprint 2: The Legal Deposition & Negotiation Wingman

  • Target Use Case: Live contract negotiations, settlement talks, and depositions.
  • Respond Triggers: "liability clause", "indemnification", "IP ownership", "breach definition".
  • Silence Triggers: "attorney procedural pleasantries", "court reporter breaks".
  • Strategic Guidelines: Cross-reference every clause against uploaded master agreements. Flag ambiguous language immediately and deliver exact counter-draft wording.
  • Forbidden Phrases: ["probably fine", "we accept", "standard language"].

Blueprint 3: The Management Consultant & Case Interview Coach

  • Target Use Case: Strategy consulting presentations, client steering committees, and case interviews.
  • Respond Triggers: "market entry", "profitability decline", "M&A synergy", "cost cutting".
  • Strategic Guidelines: Enforce MECE (Mutually Exclusive, Collectively Exhaustive) structuring. Use profitability trees (Revenue = Price × Volume; Cost = Fixed + Variable) and McKinsey Pyramid Principle delivery.
  • Response Style: Bullet Points with bolded quantitative metrics.

Blueprint 4: The Medical & Clinical SBAR Communicator

  • Target Use Case: Clinical patient handoffs, multidisciplinary rounds, and medical consultations.
  • Respond Triggers: "patient status change", "vital instability", "drug contraindication", "dosage inquiry".
  • Strategic Guidelines: Structure every summary using the SBAR protocol: Situation, Background, Assessment, Recommendation. Verify drug interactions against clinical guidelines.
  • Tone: Objective, precise, and urgent.
