Describe an app in chat and ship it
Describe your product in natural language and AI agents produce a functioning app rather than snippets or mockups.
Frontend and backend are generated together, so apps have real logic, data handling, and connectivity, not just UI.
Generated apps are deployed to a live URL right away, so you can share and test without setting up infrastructure.
The output is a standard codebase you can download, edit, and move into your own toolchain or repository.
Generate, explain and bookmark code with an AI programming assistant
Describe what you need in plain language and SpellBox writes the code for you.
Paste in existing code and get a fast explanation, so you can understand unfamiliar logic without deep documentation dives.
Save snippets you generate and retrieve them later, useful when juggling multiple projects.
Use SpellBox inside VS Code or JetBrains IDEs instead of switching to a separate app.
