Stop rebuilding context every session
Stop sending your code to the cloud

Typical Cost of AI for Programmers:
$100/year for Copilot, $20-$200/month in API usage, additional cost from inefficient workflows and timeouts
This is costing you more time and money then you can afford to lose!
Especially if you still get poor results…
Run it local, on your own machine, on your own code, and pay for it once.
One Price – One Tool – Code Faster and Save Money
Reliable results without inconsistent AI output
| Most users are working the hard way. | Here is what you get instead. |
|
GitHub Copilot costs $100 a year. It only works with GitHub’s AI. Your code goes to their servers. You have no choice of model, no offline option, and no way to keep your code local. ✕ Locked into one AI provider |
If you already use Ollama, OpenAI or Claude API, this tool connects to what you already have. Ollama AI Assistant connects to any AI you already have, works directly inside Visual Studio, and you pay once. ✓ Connect to Ollama, OpenAI, Claude, or any compatible provider |
What Is AI Assistant for Visual Studio
AI Assistant for Visual Studio is a complete AI coding workflow docked inside Visual Studio Community and Visual Studio Pro.
This replaces your entire AI workflow stack by placing your AI assistant INSIDE your code AS you are working!
Original built for Ollama, the AI Assistant now supports all major AI providers, such as OpenAI, Claude, Google and others.
(These providers do come at their own cost, and you will need to pay their service fee. Provider support is not a paid feature.)
This is not a browser tab, a chat window or side panel. The Ollama AI Assistant is an extension for Visual Studio that lives right there inside your IDE, your project files, and your source code; exactly where you work.
“The AI coding assistant that lives inside your Visual Studio.”
How Ollama AI Assistant Works
Chat Panel — ask questions about your open file, selected method, or entire solution. Responses stream in real time.
Right-Click — select code and right-click options for direct correction or summaries
Inline Completions — [AI] suggestions appear in the standard Visual Studio completion list. Accept with Tab. Dismiss with Escape.
Diff View — every AI code suggestion opens a side-by-side diff first. Review it before it touches your files. You are always in control.
Fix Build Errors — one click sends your error list to the AI. It finds the relevant code and tells you what to change.
Git Commit Messages — the AI reads your staged changes and writes a properly formatted commit message every time.
Any AI Provider — Ollama, OpenAI, Claude, LM Studio, Groq, Azure OpenAI, Mistral, and more. Switch anytime without reinstalling.
Your AI. Your choice. No subscription. No lock-in.
Why This Matters
Visual Studio AI Assistant lets you use an AI directly in your code, without relying on mandatory cloud services or monthly subscriptions.
Combined with offline local LLMs you can cut $100/year in Copilot and up to $200/month in API cost.
Put those together and Visual Studio AI Assistant will pay for itself in 1-3 months!
Best of all, running local means your data stays at your company. No leaks, no breaches, no sending your source code to some company that cares more about profit then they care about your security.
Why not just use free tools?
Yes, you could use free tools, but you are not going to find one that has everything we offer.
You can combine free tools, but maintaining that setup becomes fragile and time-consuming.
If that is something you are willing to deal with, then absolutely, go for it.
Heck, that is why I made Visual Studio AI Assistant. I made it because I could not find a tool for Visual Studio that did everything I wanted as a developer.
If you can find a better tool, then use that instead. ~Kyle Gray – CEO
Data Chunker Pro Integration
Know your entire codebase. Not just what is open.
Data Chunker Pro is an engine that makes large-context AI actually usable.
If you have ever tried to feed an entire codebase or project into an AI, then you will know it loses control very fast.
Data Chunker Pro organizes and converts entire code bases and directories into usable knowledge AIs can understand. This is an invaluable tool for getting AIs to understand and diagnose source code.
From source code, compiled binary, COBOL and even documentation databases, Data Chunker Pro makes your AI LEARN your stuff.
Together, these two products turn your local AI into a full-scale development system!

Frequently Asked Questions
- Do I need to run my own AI server?
No. Use OpenAI or Claude with just an API key — no server setup needed. Or run Ollama free on your own machine for zero cost per query and complete privacy. Your choice, changeable any time in settings. - What Visual Studio versions are supported?
Visual Studio 2022 Community, Professional, and Enterprise. Windows 10 and Windows 11. - Does this work with VS Code?
No. This extension is built specifically for Visual Studio (the full IDE, not VS Code). It uses Visual Studio’s native extension API and dockable panel system. - What programming languages does it support?
All of them. C#, VB.NET, C++, Python, JavaScript, SQL, and anything else you can open in Visual Studio. - What is the lifetime license exactly?
You pay once. You own the license permanently. No subscription, no renewal fee, no expiry date. The extension continues to work indefinitely. - Can I upgrade from Personal to Pro later?
Yes. Purchase the upgrade and enter your new license key. No reinstall required. Your settings, memory bank, and chat history carry over automatically. - What is Data Chunker Pro?
A separate Gray Technical product that converts any file — including compiled binaries — into AI-ready knowledge chunks. The DCP button is available on all editions. Learn more at our product page here. - Is there a money-back guarantee?
Yes. Not satisfied within 30 days? Email support@graytechnical.com for a full refund.
More Advanced Features Tools
These functions are available for the developer that needs high functioning tools fast! Most of these features are not even available to the average user of cloud based AIs, but I personally believe it not gatekeeping functionality. Unless you need it for team development, anything that you can do solo can be done at any tier!
We built this product for developers who mean business!
| Test Generation [Personal & Pro] | Refactoring Engine [Personal & Pro] | AI Code Review [Personal & Pro] |

Skip what you don’t. Export the full report as markdown. | CRITICAL — bugs and crash risks. WARNING — leaks and missing handlers. SUGGESTION — clarity and naming. POSITIVE — what is working well. Enable auto-review on every commit. |
