NeuralSpark for Anthropic Claude

Your Claude key,
in a real Windows workspace.

NeuralSpark is a desktop app that runs on the Anthropic Claude API key you already hold: Claude on your own platform key, for careful long-document work. 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 Claude 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 Claude developer key

    Sign in at platform.claude.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 Claude 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 Claude dashboard.

Questions

About Claude in NeuralSpark.

Do I need a Claude subscription?

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

What does Claude cost through NeuralSpark?

Exactly what Claude charges — NeuralSpark adds nothing. Current models: Claude Haiku 4.5 (US$1.00 / US$5.00) and Claude Sonnet 5 (US$2.00 / US$10.00). Everyday use is typically US$5–15 for regular use 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 Claude make images?

Anthropic Claude is text-only, so NeuralSpark labels it that way and Chat asks you to connect Meta Muse, Google Gemini, OpenAI or xAI for pictures. You can connect several providers and choose a default per job.

Is my data used for training by Claude?

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