About

SecondBrain – Your Autonomous External Mind by ReelSights AI

SecondBrain turns your calibrated Cognitive Clone into a real-time execution engine that lives natively inside Gmail and LinkedIn.

It doesn’t just generate text. It remembers your history, understands your decisions, and executes your strategic intent. Every reply, comment, and message feels authentically like you—but faster and more strategic.

No generic tone. No starting from scratch. Just your mind, extended.

How It Works
1. Calibrate: Set up your Cognitive Clone in the ReelSights Command Hub.
2. Install: Add Second Brain from the Chrome Web Store.
3. Execute: Open any Gmail thread or LinkedIn post. The sidebar appears.
4. Command: Type a prompt (e.g., "reply," "summarize," "politely decline").
5. Review: Get a high-fidelity draft (85–95% accuracy) in your exact voice.
6. Insert: Click `[ ◪ ] Insert` to push text directly into the compose box.

Core Capabilities
*   Contextual Memory: Recalls past conversations and relationship dynamics.
*   Autonomous Architecture: Suggests your next moves and strategic angles.
*   High-Fidelity Cloning: Mirrors your rhetorical style and vocabulary.
*   Surgical Insertion: Direct integration into the compose box. Zero copy-paste.
*   Encrypted Privacy: The system only reads open threads when you explicitly request assistance.

Currently Supported
*   Gmail: Complex threads & strategic replies.
*   LinkedIn: Direct Messages, high-status comments, and feed strategy.

Requirements
*   Active ReelSights OS account (Pro-Trepreneur tier).
*   Chrome or Edge browser.

Part of the ReelSights AI ecosystem—built on the same Cognitive Clone foundation as your Revenue OS.
