Psi
- Parallelize your AI agents: run 5 to 10 coding sessions simultaneously, each in its own worktree, multiplying your development throughput
- Branch out like the letter Psi: Git worktrees provide lightweight but full isolation, letting agents work concurrently without conflicts or coordination overhead
- Better code, not worse: parallel agents force you into specs, feedback, and high-quality code reviews - detailed human oversight meets machine throughput
Parallelization Is the Multiplier
A single AI coding agent is powerful. Ten agents working in parallel are transformative. But parallelization only works when agents don't collide. Psi solves this by creating isolated Git worktrees for each session, giving every agent its own workspace. No file conflicts, no merge chaos, no waiting. Just parallel execution at scale.
Better Code, Not Worse
A common fear: letting AI agents loose will produce bad code. The opposite is true. When agents handle the typing, you focus on what actually determines code quality:
Specify First
Clear requirements before execution. You think harder about what you want because you're instructing, not improvising.
Guide as You Go
Real-time guidance as agents work. You steer direction instead of getting lost in syntax.
Review in Detail
Proper code review on every change. You read code with fresh eyes, catching issues you'd miss in your own work.
Built for Parallel Workflows
Lightweight but Full Isolation
Each session runs in its own Git worktree. Agents never interfere with each other or your main codebase, enabling genuine parallel execution.
5 to 10 Agents in Parallel
Spin up as many sessions as you need. Whether you're tackling a backlog of features or exploring multiple approaches to the same problem, Psi keeps them all running concurrently.
Zero Coordination Overhead
No need to orchestrate who works on what file. Branches diverge naturally, and you merge only the results you want. Parallelization without the complexity.
Parallel Workflow in 4 Steps
Initialize
Run psi init in your
project root to set up the Psi environment.
Branch Out
Use
psi session create to
spawn isolated workspaces. Create 5, 10, or more in
parallel.
Work in Parallel
Work with each AI agent in its session. They execute simultaneously, each in its own workspace, with no conflicts.
Converge
Review branches, merge the work you want, discard the rest. Clean up sessions when done.
Single Binary. Zero Dependencies.
Drop it where you need it. Psi is a single, lightweight, statically linked executable with no external dependencies. It integrates seamlessly into any development workflow.
