NeuralSpark for OpenAI

Your OpenAI key,
in a real Windows workspace.

NeuralSpark is a desktop app that runs on the OpenAI API key you already hold: OpenAI's API models and gpt-image on your own platform key, instead of a ChatGPT subscription. Chat with sources, decks and documents designed in the conversation, Cowork files and remote servers over SSH — bought once, yours on two PCs.

Why a desktop app

More than a chat box

NeuralSpark puts OpenAI to work on your PC: comparison cards with the pages they came from, a designer in Chat that makes decks, documents, posters and web pages and checks every page, Cowork that writes files into your own folders after asking once, and your own servers over SSH with every action audited. Your work stays on the PC.

Connect more than one provider and switch per conversation. Prices in Australian dollars, GST included, one payment.

Getting going

Ten minutes, once.

  1. Get a OpenAI developer key

    Sign in at platform.openai.com, add a little prepaid credit if asked, and create an API key. Copy it once.

  2. Install NeuralSpark

    Buy once at accounts.neuralspark.com.au, download, enter your activation key.

  3. Paste the key

    Settings › Connections › Models › Connect a provider. NeuralSpark recognises OpenAI from the key, lists the models it can reach and tests the connection.

  4. Bring a real job

    Ask a comparison question, brief Cowork, or describe a design. Usage shows to the cent in your OpenAI dashboard.

Questions

About OpenAI in NeuralSpark.

Do I need a OpenAI subscription?

No. NeuralSpark uses a developer API key from platform.openai.com/, not a chat subscription. You pay OpenAI for what you use, at their published rates.

What does OpenAI cost through NeuralSpark?

Exactly what OpenAI charges — NeuralSpark adds nothing. Current models: gpt-5-mini (US$0.25 / US$2.00) and gpt-5.2 (US$1.75 / US$14.00). Everyday use is typically a few US dollars on gpt-5-mini a month.

Does NeuralSpark see my key?

No. The key is kept in Windows' protected storage on your PC and is sent only to the provider. Nothing about your usage is sent to NeuralSpark.

Can OpenAI make images?

Yes — OpenAI makes pictures on the same key.

Is my data used for training by OpenAI?

OpenAI: not used for training. NeuralSpark shows this in Settings next to each model.
