A marketing tool that runs on your own AI key

Loudwell doesn't sell AI credits. You add your own key from Claude, ChatGPT or Gemini, and your provider bills you at their price. That's why the app itself starts at £4.99 a month.

What bring your own key means

  • You get an API key from your AI provider and add it to Loudwell.
  • The key stays in your Mac's Keychain.
  • Your provider bills you directly, with no markup from Loudwell.
  • You set a monthly cap, and Loudwell stops there.

Which keys work

  • Claude, ChatGPT or Gemini for writing.
  • Gemini also makes pictures, video and voice-overs, if you want them.

What it costs

Usually £2 to £4 a month for one brand posting about once a day, on top of £4.99 a month for Loudwell. Your bill goes up if you post more. If every post used AI pictures, it would be nearer £9, and AI video costs more.

The trade-off

It's one more thing to set up, and one more bill. If you'd rather have AI included in the price, tools like Later or Buffer build it into their plans. With your own key, you see exactly what you spend.

Questions

Is a ChatGPT or Claude subscription the same as an API key?

No. An API key is separate from a chat subscription, and your provider bills it by use. You create one on your provider's developer site.

Does Loudwell see my key?

No. It stays in your Mac's Keychain, and your Mac talks to your AI provider.

What happens when I reach my cap?

Loudwell warns you at 80% and stops at 100%.

Can I use one key for Social, Sales and Comms?

Yes. All three tabs run on your own key.
