AI app builder vs AI coding assistant
An AI coding assistant lives inside your editor and helps with the file you are already in: completions, edits, answers about code you have open. An AI app builder starts a step earlier — you describe an application that does not exist and it produces one that runs. They overlap in the middle and are genuinely different tools at the edges.
| Adrian | The usual shape | |
|---|---|---|
| What you start with | A sentence. There is no project yet. | A project, a repository and an editor you are already working in. |
| What you get back | A running application with a live preview beside a full editor. | Code in the file you had open, which you then run yourself. |
| Who checks the result | A compile gate, then deterministic checks that read the code against the request and hand findings back for repair. | You do. The assistant proposes; accepting and verifying is the developer's job. |
| Who it assumes you are | Someone who wants the application, whether or not you read the code. | A developer. The workflow is built around one. |
| Where it runs | A desktop application on your machine. Windows today; macOS and Linux are not released yet. | Inside an editor, usually calling a hosted model. |
When Adrian is the better choice
- There is no project yet and writing the scaffolding by hand is the part you want to skip.
- You want the result checked before you see it rather than reviewing every suggestion yourself.
- You want the whole thing — design pass included — not just the code for the part you were thinking about.
- You want it to run with no account, no key and no bill, on a model on your own hardware.
When it is not
- The project already exists. An assistant is built for changing code you have; a builder is built for producing code you do not.
- You are a developer working at the level of the file. Nobody wants a whole app regenerated because a function needed fixing.
- You are on macOS or Linux — Adrian has not shipped there, and assistants run wherever your editor does.
- You want to stay in the editor you already know, with your own extensions, keybindings and workflow around it.
Common questions
- What is the difference between an AI app builder and an AI coding assistant?
- A builder starts from a description and produces a whole running application; an assistant starts from code you already have and helps you change it. The practical test is whether the project exists yet. If it does, an assistant is usually the better tool, and Adrian is not trying to replace one.
- Can an AI app builder replace a coding assistant?
- Not really, and it is worth saying so plainly. Once a project exists and you are making a targeted change to a file you have open, an assistant inside your editor is a better fit than regenerating through a build pipeline. Adrian ships a full editor for exactly that reason — some edits are faster to make than to describe.
- Do I need to know how to code to use an AI app builder?
- No, though it helps when something goes wrong. Adrian is built so the thing it hands back already compiles and has been checked against your request, which is the part that usually needs a developer. It is a floor rather than a guarantee: passing every check means nothing provable is wrong, not that the app is good.
- Which one is cheaper to run?
- Adrian is free on local models through Ollama and costs your provider's own rates on your own key, with no cut taken. Assistants are typically a subscription. The honest caveat is that a build system spends more tokens than an assistant does for the same question, because it plans, generates, reviews and repairs — so on a paid model the per-task cost is higher even where the tool is free.
The desktop app is free with local models or your own API key. Windows today — macOS and Linux are not released yet, and the build is unsigned, so Windows shows a SmartScreen warning on first run.
