  • No data collection
  • No tracking
  • Works fully offline
  • Built for privacy-sensitive workflows
Efficiency
Ocno reduces cognitive friction and eliminates unnecessary context switching while cutting dependency on expensive AI subscriptions.
  • Less tab switching for context
  • Information available when needed
  • Faster decision-making and research
  • Reduced reliance on cloud AI tools
  • No subscription costs

What enabled this?

5-10x Faster

Thanks to its compiler-optimized engine and full GPU utilization, Ocno delivers up to 5–10× higher performance compared to traditional CPU-based in-browser model execution.

Smaller models are catching up 🔥

Smaller models like Qwen3 4B (GPU and 4GB RAM needed) can achieve quality comparable to large earlier models such as GPT-4o in many tasks proven by various benchmarks.

Model Compression & Quantization

Advances in quantization and model compression drastically reduced memory requirements, making powerful models practical on everyday devices. You can now run model comparable to GPT-4o on just 3–4 GB of RAM — enabling capabilities once limited to large cloud systems.

What hardware do you need?

AppleWindows

MacBook M1 (Apple Silicon)

Ocno has been designed, developed, and extensively tested on Apple Silicon devices, including MacBook Pro M1 and MacBook Air M1. Apple Silicon’s unified memory architecture and high-efficiency GPU acceleration provide excellent performance for local AI inference. Newer Apple Silicon chips (M2, M3, and beyond) deliver even smoother performance and enable the use of larger and more capable models.

How Builders use Ocno

In the morning, Ocno surfaces relevant updates based on what you’ve been exploring — frameworks, libraries, tools, discussions — pulled from multiple trusted sources.

While building or debugging: “I’ve seen this before.” Ocno reconnects past solutions, research, and documentation.

While reading documentation or technical articles: Ask Ocno. Explain this. Ocno clarifies concepts directly on the page.

One Cognitive Layer

Everything you read, explore, and think — connected.

Ocno

Personalized Feed

Ocno surfaces updates based on your real interests — not generic algorithms. Query posts. Summarize insights. Understand why they matter. Explore related signals. Your curiosity becomes the filter. Your are not compared to others. You are compared to you.

Contextual Intelligence

Ask Ocno directly on the content you’re viewing. Explain concepts, clarify details, or generate concise summaries instantly. No copying. No switching tools.

Ocno Brain

Your browsing becomes a connected cognitive map. Pages, ideas, and topics form structured relationships. Search through questions. Explore connections visually. Reconnect past context instantly.

Ocno

Continuous Context

Ocno connects your current page with what you’ve read before. Relevant context resurfaces automatically. Next meaningful steps are preselected.

Expand Your Writing

Write key points. Let Ocno refine, expand, restructure — or translate your text instantly. Perfect for emails, reports, and drafts.

Guided Actions

Ask Ocno how to accomplish something on a page. Steps are identified and highlighted directly in the interface. No searching through menus. No friction.
