Nexy app for MacOS - Control computer

Hi Cliff,

That’s a great question.

At the moment, Nexy doesn’t support API keys, and this was a deliberate decision.

I’ve spent the last two years building Nexy and optimizing AI costs. The challenge is that a single voice command isn’t just one API call. It typically requires 4–5 LLM requests, each carrying a large amount of context (screenshots, UI state, conversation history, tool descriptions, etc.), often around 20–30K tokens. As a result, even a simple task can consume around 100K tokens.

For someone using Nexy actively—around 100 commands per day, which is a realistic usage pattern—that’s roughly 10 million tokens every day. With today’s high-quality reasoning models, API costs can quickly grow into hundreds of dollars per month, depending on the model and provider.

I didn’t want to build a product that would only be affordable for a small number of people. My goal is the opposite: I want people to simply use Nexy without worrying about tokens, API bills, or unexpected costs. I want you to spend your time getting things done on your Mac, not managing AI usage.

That’s why I chose to build Nexy around a ChatGPT account. If you decide it’s useful for you, you pay one predictable subscription to ChatGPT and simply use Nexy without thinking about anything else. Our goal is to keep Nexy itself affordable as well (around $5/month) so that as many people as possible can benefit from it.

That said, API support is something we’ll continue to evaluate in the future if we can provide it without significantly increasing costs or complexity for users.

Thanks again for the suggestion!

Hi guys!
I wanted to share a quick update on Nexy.

We’ve been expanding what Nexy can do beyond everyday Mac control. You can now use your voice to work with tools like Google Sheets, Google Docs, Slack, and HubSpot.
The goal is simple: make everyday work on a Mac faster and easier for blind and low-vision users.
I’d love to hear what you think and what other work tools you’d like Nexy to support.

Hi guys!

I wanted to share another small Nexy update and show what it can now do with Google Docs, Google Sheets, and Apple Mail.

Watch the new demo

I’d also really love your feedback. What would you like to see in the next videos? What problems or tasks would you like Nexy to help you solve?

Your feedback will help me decide what to build and demonstrate next.

Hi guys,
I’d like to share a new Nexy update and a short demonstration of how blind and low-vision Mac users can manage email using voice commands.
In the video, Nexy can:
Read unread emails and identify important messages.
Find personal emails or a specific message without knowing the sender.
Read complete email conversations and threads.
Prepare, edit, send, and reply to emails.
Find someone’s email address using only partial information.
Read a verification code received by email and help the user sign in to an account independently.
Watch the demonstration here:

Hi guys,

I wanted to share a quick Nexy update. Nexy is a voice assistant for Mac that helps blind and low-vision users control and automate their computer using voice.

We currently have only 5 free testing spots left, so if you’d like to join Nexy and try it for yourself, now is a good time.

Hi Daniel

Good question.

I haven’t looked deeply enough into Apple’s Foundation Models yet to give you a confident answer, but I’m going to look into it properly.

My first thought is that some simpler requests could probably be handled locally. The bigger question is whether Apple’s model can work well with the tools Nexy needs, like MCP integrations, other plugins, and Computer Use.

If it can understand those tools, choose the right actions, and work reliably with things like the DOM and Accessibility AX, then it could be very useful. If not, we would probably still need an external cloud model for the more complex tasks.

So I don’t want to make any promises yet. From what I’ve seen, Apple is still behind some other AI providers in certain areas, but I’ll test what’s actually possible and see if there’s a good way to use it in Nexy.

Thanks for letting me know. I’m actually curious about it.

Most of my development and testing has been on an M4. I also tested Nexy on an M1 MacBook Pro with 16 GB of RAM, and it worked fine there. That’s why it’s a little difficult for me to say what caused the high resource usage in your case.

In general, I’d recommend at least an M1 or newer for Nexy.

Could you tell me exactly which processor your Mac has and how much RAM? If possible, I’d like to test Nexy on a similar configuration and see whether I can reproduce the same behavior.
