By the end, you'll have a repeatable cadence for monthly refreshes, turning raw sales data into a trusted, offline superpower for your team.

What Is AI and Why Does It Matter for Sales Coaching?

Before diving into the tools, let's break down the basics. Artificial Intelligence (AI) refers to computer systems that mimic human thinking to perform tasks like understanding language or analyzing data. In sales, AI shines in processing vast amounts of information, such as call transcripts, to extract actionable insights—like common customer objections or winning pitch phrasing—faster than any human could.

A key AI technique here is Retrieval-Augmented Generation (RAG), which combines searching a knowledge base (like your transcripts) with generating responses from a Large Language Model (LLM). LLMs are advanced AI models trained on massive text datasets to understand and create human-like responses. However, without proper preparation, RAG systems often "hallucinate"—inventing facts because the input data is unstructured or noisy.

Enter Blockify and AirGap AI from Iternal Technologies. Blockify is a patented data optimization tool that refines unstructured content (like sales transcripts) into structured "IdeaBlocks"—self-contained units of knowledge in XML format, each with a name, critical question, trusted answer, tags, entities, and keywords. This makes data RAG-ready, boosting accuracy by up to 78 times while shrinking volume to 2.5% of the original size. AirGap AI is a 100% local AI chat assistant that runs on your device (no cloud needed), using Jina V2 embeddings—a high-quality model for converting text into searchable vectors—to deliver secure, offline coaching cues. For sales teams, this means reps get instant, hallucination-free guidance on handling objections or advancing deals, even in remote areas.

No prior AI knowledge required—we'll explain every step, from setup to deployment, so you can start coaching with confidence.

Step 1: Prepare Your Sales Call Transcripts for Processing

Sales transcripts are goldmines for coaching but often arrive as walls of text: filler words, overlaps, and irrelevant chit-chat. The goal is to break them into digestible pieces without losing context. We'll use "naive chunking" as a starting point—simple splitting by character count—optimized for transcripts at 1,000 characters per chunk (about 150-200 words, ideal for capturing a full exchange like an objection and response).

Why Chunk Transcripts This Way?

• Preserve Context: Shorter chunks (1,000 characters) keep ideas intact, avoiding mid-sentence splits that confuse AI.
• Efficiency for Sales Data: Transcripts average 5,000-10,000 characters per call; chunking into 5-10 pieces ensures quick processing.
• RAG Optimization: This size works well with Jina V2 embeddings in AirGap AI, improving retrieval accuracy for coaching queries like "How did we handle pricing objections in Q3 calls?"

Tools You'll Need (Free and Easy Setup)

1. Transcript Source: Use Gong, Chorus, or Zoom's built-in transcription. Export as plain text (.txt) or Markdown (.md) files. Aim for clean text without timestamps initially.
2. Chunking Software: Free tool like Unstructured.io (open-source parser). Download from GitHub and install via Python (if you're new to this, use their no-code web demo at unstructured.io).
3. Your Computer: Any modern laptop (Windows/Mac) with 8GB RAM. No GPU needed yet.

Hands-On Chunking Workflow

1. Gather Transcripts: Collect 5-10 sample calls (e.g., discovery, demo, negotiation stages). Save as individual .txt files, e.g., "Call_001_Discovery.txt".
2. Install Unstructured.io:
   • Download Python (python.org) if not installed.
   • Open a terminal (Command Prompt on Windows, Terminal on Mac).
   • Run: pip install unstructured.
3. Chunk the Text:

   • Create a simple Python script (copy-paste this into a file named "chunk_transcript.py"):

   • Replace "Call_001_Discovery.txt" with your file path.

   • Run: python chunk_transcript.py.

4. Review Chunks: Open the output files. Each should be ~1,000 characters, ending at natural breaks (e.g., after a question). Adjust overlap to 10% (100 characters) to retain context between chunks—prevents losing key transitions like objection-to-response.

Pro Tip: For 50+ transcripts, automate with a batch script or n8n workflow (free automation tool). Tag chunks manually if needed (e.g., "Objection: Pricing" via simple text editor) for later refinement.

This step takes 10-15 minutes per transcript. You've now got clean, RAG-ready pieces capturing sales nuances like competitor mentions or deal-stage pivots.

Step 2: Ingest Chunks into IdeaBlocks with Blockify

Now, feed your chunks into Blockify to create IdeaBlocks—structured XML units that turn raw transcript snippets into coaching gold. Blockify's Ingest model (a fine-tuned LLM) analyzes each chunk, extracting a descriptive name, critical question (e.g., "How to overcome budget objections?"), trusted answer (e.g., "Rep pivoted to ROI demo, closed 20% discount"), tags (e.g., "Objection, Pricing, Demo Stage"), entities (e.g., "Competitor: Salesforce"), and keywords for searchability.

Why Blockify Ingest Excels for Transcripts

• Captures Sales Nuances: Identifies objections, talk tracks, and outcomes automatically—e.g., merging "Customer hesitant on cost" into a reusable cue.
• 99% Lossless: Preserves facts like numerical outcomes (e.g., "Deal closed at $50K") without summarization errors.
• Sales Coaching Focus: Outputs are Q&A formatted, perfect for RevOps to build playbooks.

Setup Blockify (Basic IT Manager Level)

1. Access Blockify: Sign up for Iternal Technologies' cloud trial at iternal.ai (free for small datasets). For on-prem (sovereign needs), download models from their portal (requires NDA for enterprise access).

2. Choose Model Size: Start with LLAMA 3.2 3B (lightweight for transcripts; runs on CPU). Larger (8B/70B) for complex calls.

3. API Integration: Use OpenAI-compatible endpoint. In Python (or no-code via n8n):

   • Install requests: pip install requests.

   • Script ("ingest_chunks.py"):

   • Run: python ingest_chunks.py. Outputs XML with 2-5 IdeaBlocks per 1,000-char chunk (e.g., one for objection handling, one for competitor response).

4. Process All Chunks: Loop the script for your batch. Expect 80-90% coverage—review any incomplete blocks manually (e.g., edit tags like "Stage: Negotiation" in XML).

Time: 5-10 minutes per 10 chunks. Result: Structured IdeaBlocks ready for distillation, tagged for sales scenarios (e.g., "Product: Enterprise CRM", "Outcome: Won Deal").

Step 3: Distill IdeaBlocks to Merge Duplicates and Enhance Coaching Value

Raw IdeaBlocks from ingestion may have near-duplicates (e.g., similar pricing objections across calls). Blockify's Distill model merges these intelligently, preserving unique insights while reducing redundancy—crucial for sales coaching where reps need concise, non-repetitive cues.

Benefits for RevOps and Enablement

• Merge Objections: Combine "Budget too high" variants into one trusted block with examples from multiple calls.
• Tag for Precision: Add metadata like "Competitor: HubSpot", "Stage: Demo", "Outcome: Overcame" for targeted retrieval in AirGap AI.
• 52% Search Improvement: Distilled blocks boost vector recall, ensuring Jina V2 embeddings find exact matches for queries like "Best talk track for late-stage stalls".

Distillation Workflow

1. Input Preparation: Feed 2-15 undistilled IdeaBlocks per API call (optimal for similarity detection). Use XML from Step 2.
2. Run Distill Model:

   • Update script ("distill_blocks.py"):

   • Run for batches. Set iterations to 5 for thorough merging (e.g., consolidate 10 similar "Competitor objection" blocks into 2-3 refined ones).

3. Tag and Review:
   • Open XML in a text editor. Enhance tags: <tags>Objection, Pricing, Competitor:Salesforce, Stage:Discovery, Outcome:Qualified</tags>.
   • Human Review (Key for Coaching): Spend 1-2 hours scanning 500-1,000 blocks. Edit answers for accuracy (e.g., "Rep used ROI calculator to overcome—closed 15% faster"). Delete irrelevants (e.g., small talk).
   • Export: Save as JSON for AirGap AI import.

Time: 15-30 minutes per batch. Output: A lean dataset (e.g., 2,500 blocks from 50 transcripts) with 99% lossless facts, ready for offline use.
