Introduction
Koubou is a custom AI writing tool designed for creators who need precise, high-quality content.
What is Koubou?
Koubou is a specialized writing application that provides users with full control over AI-generated content. It addresses common frustrations with generic AI chatbots, such as inconsistent output, repetitive phrasing, and a lack of contextual understanding. The product is built for content creators, educators, and entrepreneurs who require tailored results and wish to integrate AI into their workflow without sacrificing their unique voice or facing editing overload. By offering a document-like interface, Koubou positions itself as a workbench where human creativity is enhanced by AI, not replaced by it.

Frequently Asked Questions about Koubou
What AI models can I use with Koubou?
Koubou uses the OpenRouter gateway, allowing users to bring their own API key and access a wide range of AI models from different providers, offering greater choice and flexibility compared to platforms with limited, built-in models.
How does Koubou ensure the privacy of my data?
Koubou addresses privacy concerns by storing all user data locally on the individual's device. This means your projects, prompts, and generated content are not stored on company servers, minimizing cloud-related privacy risks.
Can I reuse my prompts and workflows in Koubou?
Yes, a core feature of Koubou is the ability to build a library of Smart Prompts and Visual Workflows. These can be reused across projects and customized with variables, saving significant time and effort.
How does Koubou help maintain a consistent writing voice?
The Custom Personas feature allows users to define and save detailed persona profiles. By applying these personas to your prompts, the AI output maintains a consistent voice, tone, and style, preventing the erratic changes common in generic chats.
What is the difference between a Workflow and a Prompt?
A Prompt is a single instruction given to the AI. A Workflow allows you to chain multiple prompts and steps together in a visual sequence, automating more complex content creation tasks directly within your document.
Is there a limit to how much I can use the AI?
Since Koubou uses a Bring Your Own Key (BYOK) model via OpenRouter, your AI usage is governed by the terms and credits of your chosen AI model provider, not by Koubou itself, effectively offering unlimited usage based on your external account.
