Coding assistant from the Blackbox team...
Start the command-line tool in a project and describe the API or page you want. Let it list steps before it edits files. After an error, ask it to continue from the command output instead of pasting the stack into another window. To compare approaches, make sure the folder is a Git repository, then run multi-agent so each implementation lands on its own branch. Review the differences before merging. For a working app from a product description, use the web Builder and download the source to deploy it yourself. Copy a key from the dashboard and select a provider with the configure command first. It fits developers who want scaffolding, edits, and debugging in one terminal flow.
BLACKBOX AI is a coding assistant from the Blackbox team in San Francisco. It includes a terminal command-line tool and a web Builder. In the terminal you describe a feature in natural language, and it plans the steps, creates and edits files, installs dependencies, and keeps debugging after errors. It can also add tests, look at performance and security issues, and set up build and deployment. Multi-agent mode opens a separate Git branch for each implementation in an existing repository. Builder turns a written description into interface, API, and data layers, and lets you download the source. You need to log in and configure a key first.
Difficulty: Intermediate
Create a project from a description
After you describe the stack and features, the command-line tool initializes the folder, installs dependencies, and generates the API or pages.
Keep debugging after errors
It can identify compile and runtime errors, run commands, keep editing from the output, and add unit tests for an existing module.
Multi-agent branches
In an initialized Git repository, multi-agent mode implements the same task in parallel and puts each approach on its own branch for comparison.
Search from the terminal
When a question needs current information, the command-line tool searches and includes sources. The docs attach this ability to the official configuration.
Build an app on the web
Builder turns a description into an interface, service API, and data layer, and lets you download readable source to run in your own environment.
Scaffold an API from a description
A backend developer describes the resources and fields in the terminal and lets the tool create the project layout, dependencies, and basic CRUD API.
Compare implementations before merging
Run multi-agent on one request in an existing Git repository, inspect each branch, and merge the implementation you want to keep.
Turn an idea into downloadable code
A product owner describes screens and data in Builder, then downloads the source for an engineering team to continue.
After installation, run the configure command, pick a provider, and paste the key from the dashboard. The docs give an install script for Unix-like systems and an install command for Windows. If Windows blocks the script, relax the execution policy for the current session and install again. Then start it in a project and describe the feature in natural language. You can reopen configuration later to change the model source.
A single chat edits the current workspace in sequence. Multi-agent mode creates a Git branch per participating agent, implements the same request in parallel, and leaves the comparison and merge to you. The docs require the current directory to already be a Git repository. Some agents also need an extra key in the configuration, or that implementation will not appear. It fits tasks where you want several structures before choosing one.
