Your setup is the part worth keeping.

The hard part of good AI work is the setup around the prompt. The rules for your voice, the facts about your business, the prompts you have tuned over months. New models come out every few weeks. Your setup should not have to start over with each one.

It also means you can check for yourself. When everyone is talking about a new model, run your own prompt on it, on your own draft, and decide whether it is better for your work.

Compared with ChatGPT and Claude.

In ChatGPT or Claude

  • A Custom GPT runs on OpenAI models. A Claude Project runs on Anthropic models.
  • To try another company's model, you rebuild your instructions and upload your files again in that company's app.
  • Each app keeps its own copy, so a fix you make in one does not reach the other.

In Koubou

  • Models from many companies through one OpenRouter account, plus local models through Ollama.
  • Switching is one setting. Nothing gets rebuilt or uploaded again.
  • Your setup is stored in your browser, not inside any AI company's app.
