Understand, then build
Trace a feature across modules. Find the conventions and constraints. Plan the next change before editing.
For teams with established codebases
Build on your codebase.
Bring the repository your team ships. Explore the architecture, build a feature, or work through a refactor or migration. Inspect the code changes and terminal output as you go.

What is next for your codebase?
For maintainers of established private repositories: company products, internal systems and client applications with years of development behind them.
Refactor across files
Untangle a shared module, replace an old pattern or prepare a service for the next feature. Review a bounded first change.
Take on a migration
Explore a Scala migration, an Elixir application change or a framework transition. Map dependencies and define checks before changing behavior.
Start with one real repository
- Download the desktop app and open your existing project.
- Choose a repository you are authorized to use and describe the outcome you want.
- Ask for a plan, then inspect the changes and validation results.
Working with client code? Use a project you have permission to work on with Lemon Code. Read how code and activity are handled.
DownloadWork with the whole picture.
Start with the existing architecture and conventions. Ask Lemon Code to inspect the relevant files, make a scoped change and run available checks.
Automate workflows.
Connect the apps you already use. Lemon Code reads from them, takes the steps, and reports back, once or on a schedule.
GitHub, Slack, Notion, Gmail, Jira, Linear and more than 1,500 other apps, plus your own MCP servers.
