From idea to shipped code
ChatML turns you into a manager of AI coding agents. Scope, delegate, and review — all from one place.
Scope the task
Define what you want built. Create a session with a clear objective and ChatML sets up an isolated git worktree automatically.
Delegate to agents
Spawn parallel Claude sessions, each working in isolation. Multiple features, bug fixes, or refactors running at the same time.
Review and ship
Review diffs, run code reviews at multiple depths, and create pull requests. Merge when ready with full visibility into every change.
Why not just use the terminal?
Claude Code CLI is powerful. ChatML makes it even better.
Parallel sessions
Unlimited parallel agents with isolated worktrees, managed from one UI
One session at a time per terminal tab. Manual worktree setup.
Code review
Built-in diff viewer with Quick, Deep, and Security review modes
Manually review changes with git diff in terminal
Cost tracking
Real-time cost and token monitoring per session with budgets
No built-in cost visibility
PR workflow
Create, review, and manage PRs directly from the app
Separate gh CLI commands in a different terminal
Context isolation
Automatic git worktree per session, zero conflicts
Manual branch management, risk of conflicts
Visibility
Dashboard showing all session status, progress, and activity
Switch between terminal tabs to check status
Everything you need to ship faster
Scope tasks, delegate to agents in isolated worktrees, and review their work async.

Loved by developers
See what developers are saying about building with ChatML.
ChatML completely changed how I work with Claude. Running three agents in parallel while reviewing diffs in real-time is a game changer for my workflow.
Alex Rivera
Senior Engineer at Vercel
The git worktree integration is brilliant. I can have multiple features being developed simultaneously without any branch conflicts. It just works.
Sarah Chen
Staff Engineer at Stripe
I went from running one Claude session at a time to managing five in parallel. The cost tracking alone has saved me hundreds in API costs.
Marcus Johnson
Tech Lead at Linear
The code review feature with three depth levels is exactly what I needed. Quick reviews for small changes, deep reviews for complex PRs. Love it.
Emily Park
Full-Stack Developer at Notion
As a solo developer, ChatML makes me feel like I have a team. I delegate tasks to agents and review their work like a tech lead.
Daniel Okoro
Indie Developer at Self-employed
The PR workflow integration is seamless. From scoping a task to merging a pull request, everything happens in one app. No more context switching.
