 5  Since the last update, Epic 7 has been completed, bringing conversational intelligence to the heart of InterBrain. This release transforms how we share knowledge during conversations - making real-time transcription, semantic search, and AI-powered summaries first-class citizens in your spatial knowledge network.

 7  ## Digital Campfire Mode

 9  **[VIDEO 1: Copilot Mode Demo]**
10  
11  When you start a video call with someone in your vault, InterBrain enters "Digital Campfire" mode - your conversation partner moves to the center while real-time transcription captures every word. Press and hold the Option key to reveal a semantic search honeycomb showing relevant DreamNodes based on the last 500 characters of conversation context.
12  
13  The system runs entirely locally using whisper_streaming for sub-5-second latency transcription. When something relevant comes up, simply click a DreamNode to "invoke" it - marking it for automatic sharing after the call ends.
14  
15  ## Songline: Perspectives Across Time
16  
17  **[VIDEO 2: Songline Feature Demo]**
18  
19  Every conversation becomes a living artifact. The Songline feature automatically generates audio clips from your conversation using LLM-powered segmentation, creating a timeline of perspectives around invoked DreamNodes.
20  
21  When you later open a DreamNode that was discussed across multiple conversations, you'll see all the perspectives - different moments in time when you and others explored that idea together. Each audio clip is a window into how your understanding evolved through dialogue.
22  
23  ## One-Click Knowledge Sharing
24  
25  **[VIDEO 3: Post-Call Summary & URI Cloning]**
26  
27  After ending a Digital Campfire session, InterBrain generates an AI-powered conversation summary with all invoked DreamNodes embedded as Obsidian URI deep links. Click "Export to Email" and Apple Mail opens with a pre-filled message ready to send.
28  
29  Your conversation partner receives clickable links that instantly clone the referenced DreamNodes into their vault - either via the Radicle network or GitHub fallback. No manual exports, no file attachments, just seamless peer-to-peer knowledge transfer.

31  ## Technical Implementation
32  
33  Key technical achievements include:
34  
35  **Real-Time Transcription Infrastructure**
36  - whisper_streaming integration with LocalAgreement-2 for duplicate prevention
37  - Python virtual environment isolation with cross-platform dependency management
38  - Sub-5-second latency speech-to-text with automatic file updates
39  - Robust process lifecycle management with graceful cleanup
40  
41  **Semantic Search Integration**
42  - 500-character rolling context window for focused search relevance
43  - Option key press-and-hold to show/hide search results honeycomb
44  - Real-time node discovery driving conversational flow
45  - Invocation tracking decoupled from selection for clean UX
46  
47  **AI-Powered Summarization**
48  - Claude API integration via Obsidian's requestUrl (CORS workaround)
49  - Provider abstraction layer supporting multiple LLM backends
50  - Conversation summarization with invocation context awareness
51  - Graceful fallback when AI API unavailable
52  
53  **macOS System Integration**
54  - FaceTime automation with AppleScript execution
55  - Apple Mail draft generation with pre-filled content
56  - Contact metadata system (email/phone) for person DreamNodes
57  - Automatic copilot mode activation on call start

59  ## What's Next
60  
61  With Epic 7 complete, we now have a foundation for conversational AI-powered knowledge work. Epic 8 will focus on the Coherence Beacon System - automatic relationship discovery, bidirectional tracking, and distributed publishing infrastructure that makes the knowledge network truly alive.
62  
63  The journey continues toward DreamOS - a decentralized operating system for collective sensemaking.
64  
65  ## Getting Started
66  
67  Complete setup instructions are available in the [project README](https://github.com/ProjectLiminality/InterBrain). Installation is straightforward - download the latest release, drag the folder to your Obsidian plugins directory, and enable the plugin.
68  
69  **Note:** InterBrain is work-in-progress software built transparently in public. The conversational features require Python 3.10+ for transcription and an optional Claude API key for AI summaries.
