Yes, separately. Koubou does not include AI credits. You bring your own, and you pay whoever you bring.

Two providers run a prompt from inside Koubou:

• OpenRouter: Connect your account and choose among supported models. OpenRouter bills usage directly.
• Ollama: Connect a compatible local instance and run installed models on your machine. Nothing leaves the machine and no one bills you per token. The hardware, setup, and speed are yours.

If your machine can already run a model locally, Ollama is the cheaper of the two. You trade a per-token bill for setup work and whatever speed your hardware gives you.

Koubou never marks up model usage, and it never resells you credits.

You can, and for a one-off task you probably should. The difference shows up on the tenth task, not the first.

A Project is one pool of context attached to one chat. Its instructions and files apply to everything you do inside it, and moving any of it somewhere else means copying it by hand. Koubou keeps the same material as separate pieces you edit once and deliberately compose per task.

A Smart Prompt is one of those pieces. It saves its own role, its blueprint, the facts it reaches for, the model it runs on, and where the output lands. Use it in a different task, or drop it into a Workflow as one step, and you rebuild none of that.

Use a Project when the work is one conversation. Use Koubou when you keep rebuilding the same setup and want to stop.

No. Koubou is for people who write and make things, not for prompt specialists.

The work is writing down what you already know:

• The facts about your product, client, or audience.
• The voice you want the writing to hold.
• The structure a finished piece needs to have.

That setup costs time before it starts paying you back. What it buys is not having to explain yourself again next time.

That does not mean the skill is wasted if you have it. If you are already good at prompting and context engineering, you get more out of Koubou, not less. Every choice you would otherwise make by hand is a saved, editable part of the tool. The role, the context it pulls in, the shape of the output, the model for that particular job. Workflows then chain those tools together with branches and checkpoints, so the process you normally hold in your head runs the same way twice.

Not on its own, and we will not pretend otherwise. Koubou does not judge the result.

It keeps the setup behind good work reusable and leaves the sources, the standards, and the final decision with you.

Better inputs and a second look from you are still what make the difference. Koubou makes the good inputs easier to keep.

No. Workflows can repeat the steps you have already decided on, and they stop wherever you tell them to.

A run holds at any checkpoint you place in it:

• Review — read what it produced before it continues.
• Input — supply something only you can give it.
• Approval — say yes before anything is written.

You remain responsible for source quality, taste, editing, and final use.

In your browser, on your machine. Koubou does not store your creative workspace on Koubou servers.

Four places are involved, and only the first holds your work:

• Browser workspace. Projects and Koubou tool data live in your browser.
• Selected AI provider. AI requests go from the browser to the provider you choose.
• Optional Google features. Selected document or backup data goes to your Google account.
• Koubou services. Koubou's servers handle account, licensing, and narrow integration functions.

Your workspace stays behind unless you take it with you. Clearing browser data or moving to another machine can leave the workspace behind.

Back up the workspace before clearing browser data or moving to another machine. You have three options:

• Manual download. Workspace data and managed images. You start it. Every supported browser.
• Browser-folder backup. Rotating table snapshots and an image mirror. Automatic after you choose a folder. Browsers that support the folder-access permission, currently Chromium browsers such as Chrome and Edge.
• Google Drive backup. Five rotating table snapshots. Managed images are not included. Automatic after you connect Drive. Every supported browser, once Drive is connected.

The manual download is the complete portable copy, and it is the one to use when you change machines.

For signing in, yes. For everything else, no.

• Sign-in. A Google account is required to sign into your Koubou account.
• Google Drive. Connecting Google Drive is optional and separate from sign-in.

You can run Koubou without ever connecting Drive, and Drive backup can be turned off again at any time.
