Frequently asked questions

How this tool works, what it cannot do, and what happens to what you put into it.

  • How does the AI content idea generator work?

    The generator analyses your industry, target audience, platform, and content type, then asks a local browser AI to produce structured ideas with titles, descriptions, engagement estimates, and tags.
  • Can I generate ideas for different content types?

    Yes. Pick from educational, entertaining, promotional, inspirational, and behind-the-scenes content. Each type is steered towards your platform and audience.
  • How many content ideas can I generate?

    Use the slider to request between 5 and 20 ideas per run. You can regenerate as often as you like — every batch runs locally for free.
  • Are the content ideas customised to my brand?

    The AI tailors ideas to the industry and audience you describe. The more specific you are about your niche and brand voice, the more relevant the suggestions become.
  • Does my data leave the browser?

    No. The model runs entirely on your device — your inputs, prompts, and generated ideas never reach our servers.
  • Is my data private?

    Yes. This tool does its work in your browser, so whatever you type, paste or upload stays on your device. Nothing is sent to our servers, which is also why it keeps working if you go offline after the page has loaded.
  • Where does the AI actually run?

    On your own machine. Chrome has a built-in model that the page uses when it is available, and otherwise the page downloads an open model such as Phi-4-mini and runs it on your GPU through WebGPU. Either way your prompt never leaves the device.
  • Which browsers are supported?

    Chrome gives the best experience because it can use its built-in model with no download. Any browser with WebGPU support, including recent Edge, Firefox and Safari, falls back to an open model instead. The first run downloads that model, so it is slower than the ones after it.
  • Is this really free?

    Yes. Every tool here is free with no account, no credit card and no usage cap. They exist so that the people who need our scheduling product find us, which only works if the tools are genuinely useful on their own.
  • Do I need an account?

    No. Open the page and use it. An account is only for OctoSpark itself, where you plan, schedule and publish a whole calendar rather than fixing one post at a time.
  • Can I use the output commercially?

    Yes. Anything you produce here is yours, including for client and commercial work. We claim no rights over it and we do not watermark it.
