Introduction

Every day we generate and receive countless documents—reports, research papers, meeting notes, and PDFs. Extracting the key points quickly can save hours, but sending sensitive files to cloud services raises privacy concerns. With Octaven’s on‑device AI hardware, you can build a private document summarizer that runs entirely inside your home or office, keeping your information under your own roof.

In this guide we’ll walk through:

• The benefits of local summarization for privacy and speed.
• Setting up the Octaven environment using the touch console and mobile app.
• Preparing documents for on‑device processing.
• Running a summarization workflow on the Mini, Studio, and Pro models.
• Extending the workflow with custom prompts and multi‑agent orchestration.

No prior experience with large language models (LLMs) is required—just a curiosity about making your own AI assistant work locally.

Why Summarize On‑Device?

Data Sovereignty

Octaven’s promise—Intelligence that stays home—means your documents never leave the device. All inference happens on the local neural engine, and encrypted storage safeguards the raw files and generated summaries.

Low Latency

The Mini’s 16 TOPS engine can produce a concise summary of a 10‑page PDF in under a minute, while the Studio’s 38 TOPS and Pro’s 76 TOPS engines shave that time further for larger batches.

No Ongoing Subscription

Unlike cloud APIs that charge per token, Octaven requires no monthly AI subscription. Once the model is on the device, you can run it as often as you like.

Getting Started: Preparing Your Octaven Device

1. Install the Octaven Mobile App

• Download the app from the Octaven website onto your smartphone.
• Pair the app with your device via the built‑in touch console. The console displays each agent’s status and lets you enable the Document Summarizer agent.

2. Choose the Right Model for Your Needs

| Model | Neural Engine | Unified Memory | Storage | Ideal Use‑Case | |-------|---------------|----------------|---------|----------------| | Mini | 16 TOPS | 32 GB | 1 TB NVMe | Personal reports, occasional summarization | | Studio| 38 TOPS | 64 GB | 2 TB NVMe | Frequent summarization, multi‑document batches | | Pro | 76 TOPS (combined) | 128 GB | 4 TB NVMe | Heavy‑duty workloads, team‑wide summarization pipelines |

All three models support Wi‑Fi 7, Bluetooth 5.4, and Matter/Thread, so you can pull documents from any smart‑home device or network share without exposing them to the internet.

Step‑By‑Step Workflow

Step 1: Collect Your Documents

1. Local Sources – Drag PDFs, Word files, or plain‑text notes into the Octaven storage using the mobile app’s File Sync feature. The files are stored encrypted on the device’s NVMe drive.
2. Smart‑Home Integration – Use Matter‑compatible printers or scanners to automatically deposit scanned documents into a designated folder on Octaven.

Step 2: Pre‑Process the Text

Octaven includes a lightweight OCR engine that runs locally. To prepare a scanned PDF:

# From the console UI, select the file and choose “Run OCR”
# The output is a searchable .txt file stored alongside the original

For plain‑text or Word files, the app will automatically extract the raw text.

Step 3: Load the Summarization Model

Octaven ships with a compact, open‑source LLM optimized for edge devices (e.g., a 2‑B parameter transformer). To load it:

1. Open the Agent Marketplace on the touch console.
2. Locate “Local Summarizer v1” and tap Install.
3. The model is cached on the device’s NVMe storage; no internet download is needed after the initial install.

Step 4: Run a Single‑Document Summary

Using the mobile app:

1. Navigate to Agents → Summarizer.
2. Select a document and choose a summary length (short – 3 sentences, medium – 1 paragraph, long – 2‑3 paragraphs).
3. Tap Run.

The agent streams the result back to the app in real time. Because inference stays local, the summary appears instantly once processing finishes.

Step 5: Batch Summarization with Multi‑Agent Orchestration

For power users, Octaven’s local agent orchestration lets you chain tasks. Example pipeline:

1. OCR Agent – Converts scanned PDFs to text.
2. Chunker Agent – Splits long texts into 1,500‑token segments.
3. Summarizer Agent – Generates a paragraph per chunk.
4. Aggregator Agent – Merges paragraph summaries into a cohesive overview.

To set up:

• Open the Orchestration tab on the console.
• Drag the agents into the workflow canvas and connect the output of one to the input of the next.
• Save the pipeline as “Weekly Report Digest”.

Now you can drop a folder of weekly reports into the Input directory and let Octaven process them overnight, all without a single byte leaving the device.

Practical Example: Summarizing a Project Brief

Imagine you receive a 12‑page project brief in PDF format. Here’s how you would generate a concise executive summary on an Octaven Studio:

1. Upload the PDF via the mobile app.
2. Run OCR (if needed) – the console shows a progress bar.
3. Select the Weekly Report Digest pipeline.
4. Choose “Medium” length for the final summary.
5. Execute – the Studio’s 38 TOPS engine processes the document in ~45 seconds.
6. Review the generated summary on the touch console or share it securely with teammates via the encrypted local network.

The result is a 150‑word overview that captures objectives, timeline, key stakeholders, and deliverables—perfect for quick stakeholder updates.

Extending the Summarizer with Custom Prompts

Octaven’s agents accept prompt templates. You can tailor the tone or focus of the summary:

{
  "system": "You are a concise business analyst.",
  "user": "Summarize the following document, highlighting risks and mitigation strategies."
}

Save the template in the Agent Settings panel and select it when launching the summarizer. This flexibility lets you repurpose the same engine for:

• Legal brief digests (focus on obligations).
• Academic paper overviews (highlight methodology).
• Personal reading notes (extract actionable takeaways).

Security Best Practices

1. Enable Hardware Privacy Controls – From the console, toggle Data‑at‑Rest Encryption to use the device’s TPM‑backed keys.
2. Limit Network Access – Keep the device on a dedicated VLAN; Octaven’s Matter/Thread stack isolates smart‑home traffic from the summarizer.
3. Regularly Rotate Storage Keys – The mobile app offers a one‑click key rotation feature.
4. Audit Agent Logs – The console logs every inference request; review them to ensure no unexpected data usage.

Following these steps ensures the summarizer remains a truly private assistant.

When to Choose Mini, Studio, or Pro

• Octaven Mini – Ideal for occasional personal use (e.g., summarizing a single contract or personal notes). Its 1 TB storage comfortably holds a few hundred documents.
• Octaven Studio – Best for creators and small teams who batch‑process dozens of reports weekly. The added memory and storage support larger model caches and longer document histories.
• Octaven Pro – Designed for enterprises or research groups that need to summarize thousands of pages nightly. Thunderbolt 5 enables fast external storage expansion, and the 76 TOPS throughput handles multiple concurrent pipelines.

Conclusion

A private, on‑device document summarizer empowers you to extract insights quickly without surrendering control of your data. By leveraging Octaven’s unified memory, high‑throughput neural engine, and secure local storage, you can build a workflow that fits personal, creative, or professional needs.

Whether you start with a single PDF on the Mini or scale to nightly batch jobs on the Pro, the same principles—local inference, encrypted storage, and agent orchestration—keep your information safe and your productivity high. Start today with the Octaven mobile app, and let your eight agents turn mountains of text into clear, actionable summaries—all from the comfort of your own home.
