The whole application, with the paid rows locked rather than removed.
Latest release: NeuralVault 2.0 Beta, 15 October 2026. Expect bugs. Keep a backup of your vault. See what changed.
One installer for every plan. Your account decides what you get: sign in and NeuralVault runs as Free, Personal or Business.
By downloading you agree to the Terms (version 2.6) and the Privacy Notice (version 2.5). This is a Beta: expect bugs, keep a backup of your vault.
The installer is code-signed by Perpetual Technologies AI Ltd. Windows may still show a blue “Windows protected your PC” panel while a new certificate builds reputation: choose More info, check the publisher it names, then Run anyway.
Nothing to activate
Install it and open it. There is nothing to buy, no card, and no expiry.
It opens on a sign-in screen and the account is free to create. No card, nothing expires, and it is not a trial: the account is what carries your edition, so moving up later is a change to it rather than another download.
390+ models through one account.
With NeuralVault routing you pick a model from a catalogue of 390+ models and use it, with nothing to connect and no key to paste. Free works with your own API key or a local model. Personal does that and adds routing on top.
Your own key, or a local model.
- Cloud providers such as Anthropic and OpenAI, on your own API key.
- Local models through Ollama.
- Nothing is metered when you use your own key.
390+ models, nothing to connect.
- Everything Free does, your own keys and local models included.
- NeuralVault routing: choose a model from the catalogue, per model, in the picker.
- The NeuralVault AI score and our full model picker come with NeuralVault routing. With your own keys you get a plain model list.
- Routing is optional. Your own keys and a local model work without it. You can also use your own keys, such as OpenRouter, OpenAI and Anthropic, and that is free to use with your own keys. Routing makes it easier and nicer.
462 models were listed in the public OpenRouter model catalogue on 14 October 2026, and 393 of them can use NeuralVault's tools, which are the ones its model picker lists. Routing draws on that catalogue, so the number moves as it adds and removes models.
Three steps, none of them a payment.
- Download itThe installer above. Nothing to buy and no card, and it does not expire.
- Open it and sign inAn account is free to create. It is what tells the app which edition you are on, and on Free that answer is simply Free.
- Point it at a folderYour vault is a folder of Markdown on your own disk. Pick an existing one or let it make you a new one.
What you get for nothing
Free is not a trial and it does not expire. It is the same build the paid editions run, with fewer switches on, so nothing you learn using it is wasted if you move up later.
- Chat with Cortex over your own vaultYour notes stay as plain Markdown on your disk, searched by keyword and by meaning at once.
- It can write to your vault, and you approve each changeEvery write waits on a card showing which files it touches until you approve it, and one control undoes it afterwards.
- Any model you likeA local model through Ollama, or Anthropic, OpenAI and others on your own API key. No gate on either.

What to expect from the Beta
- It will have bugs. That is what a Beta is for.
- Keep a backup of your vault, and keep copying it.
- NeuralVault checks for updates and installs them. You can also download the newest installer from this page and run it over your copy; your vault is kept.
- Windows only. macOS and Linux are experimental, and there is no macOS or Linux installer yet.
- During the Beta everyone has Personal. In the next few weeks, when the Stable version is released, Personal becomes a monthly subscription. We will tell you before it changes.
- Personal is all your AI bills in one place: we handle the billing, the routing and the backups, and routing is only available through Personal.
- NeuralVault routing (390+ models through one account) runs on a prepaid usage balance, and the balance opens soon. Using your own API keys or a local model is free, and always will be.

How to give feedback
- Use the bug report inside the application. It takes a minute.
- This guide shows exactly what a bug report sends and what it hides.
- For anything else, write to us.
Known issues
- The licence check can lock the application if it cannot reach our service for seven days. Nothing is deleted, and it opens again when it can check in. What to do.
- The nv command-line tool is not yet signed, so Windows may warn when you run it.
What it needs to run
Free, Personal and Business are the same application with a subscription between them, so the machine needs the same things whichever one you end up on.
Windows 10 or 11, 64-bit. Windows is the main supported platform. There is no ARM build, and macOS and Linux are experimental (see below).
It installs for your user account only, so Windows never asks you for an administrator password. About 115 MB to download.
The light way to run it. The model does its thinking on your provider’s hardware, so your machine only has to run the app.
Much heavier, and worth knowing before you start. Ollama holds the whole model in memory for as long as it stays loaded.
The one local-model number worth having in advance: the model our getting-started guide suggests, qwen3.5:9b, is a 6.6 GB download, and a smaller model costs you proportionally less. We do not publish a minimum memory figure, because with a cloud provider the app is the only thing running on your machine and with a local model it is the model that decides, not us. The app carries its own browser engine, so setup fetches nothing else. The first run needs a connection only to sign in.
