Hyperlink by Nexa AI

Hey Product Hunt 👋

I’m Alex, CEO & founder of Nexa AI.

We built Hyperlink because local search on computers hasn’t evolved in 20 years.

Desktop search finds files — not answers. Cloud AI understands context — but trades your privacy to do it.

We wanted both: intelligence and privacy.

How it started

We began with a simple question:

“What if ChatGPT lived inside your computer — not in the cloud?”

That became Hyperlink — your on-device AI Super Assistant that understands all your documents, notes, and images, and gives cited answers instantly, 100% offline.

It’s like having your own private ChatGPT that knows your files, runs locally on CPU/GPU/NPU, and never sends data out.

What Hyperlink does

• Understands everything you’ve saved on computer — PDFs, notes, screenshots, slides.

• Answers in natural language with citations — “What did we decide in last week’s strategy doc?” → instant sourced answer.

• Searches with natural language, not by keywords — it gets context.

• Works fully offline — privacy by design.

What’s different

Most search tools only find keywords. Most AI tools live in the cloud.

Hyperlink bridges that gap:

• Local-first intelligence: everything runs directly on your device — no data ever leaves.

• Unlimited file context: understands and connects thousands of files and stays in sync.

• Agentic RAG: quality rivaling cloud AI

• No setup, no CLI: always-there floating UI built for anyone.

Try Hyperlink today — see what your own computer already knows about you.

Hyperlink turns your computer into an AI second brain — understanding every document, note, and image you’ve saved. It answers in natural language, cites the exact files it draws from, and runs entirely on-device — no cloud, no data sent out.

The magic happens when local context meets intelligence. Our product has been widely acknowledged by our partners: https://hyperlink.nexa.ai/

As Gerardo Delgado Cabrera from NVIDIA said, “Hyperlink makes LLMs more useful by combining them with local file context and helping users find information faster.”

Jovi Chi from AMD called it “a super AI assistant — secure, smart, and able to give clear, well-reasoned answers.”

And Dr. Vinesh Sukumar from Qualcomm noted, “Hyperlink delivers state-of-the-art retrieval and generation across your entire laptop.”

We’re just getting started — bringing true personal intelligence to every device.

This is amazing. Congrats on the launch

Apart from file context, does it also have context to troubleshoot OS-specific errors?

I've been using this tool as a local AI in pairing with my Obsidian vault. While I'm still early in using it, so far it's been so much easier and more useful than any of the local AI tools within Obsidian itself. Beyond that I can use it for local files on my laptop, even better! Great launch and can't wait to test more!

Hi @alexchen4ai I’m wondering how data privacy is handled in this tool. Since it connects and processes content locally is there any chance that user data or metadata could be sent back to their servers for analytics, telemetry, or profiling purposes?
In other words how can we be sure there’s no background syncing or data leakage happening behind the scenes?

Very cool! You’ve outplayed Siri on Mac — they’re only just planning to implement this)

Google has integrated Gemini into drive. So now if you open anything on Google drive there is a pop up of gemini that according to me does all the functions that you do. Plz tell me if there is any function that you offer that the likes of gemini and NotebookLm do not offer?
