One project context. Two ways to work.
Move between a fast terminal loop and a calm desktop workspace without losing the session context that matters.
A clearer view of the whole session.
Use a dedicated desktop window for project navigation, session history, exports, and long-running work.
Keep the important context inspectable.
OpenCtrlC works with your local project files and lets you inspect the context, tools, and output behind each step.
Built for trust
The useful parts are visible.
OpenCtrlC is built around the moments that make an agent dependable: knowing what it sees, keeping history intact, and making the result easy to take away.
Understand before you change.
Inspect the effective system prompt, skills, and context usage when you need to know why an agent is behaving a certain way.
Return to work without starting over.
Navigate session history, search through turns, collapse completed activity, and keep the conversation readable.
Take the result with you.
Export a clean Markdown summary, a complete transcript, or structured JSON for your own tools and records.
Use the machine you already have.
The release pipeline publishes CLI and Desktop packages for macOS, Windows, and Linux, including x64 and arm64 builds where supported.
