Try the current build
Install the published Windows Developer Alpha and use PAI on a real project. The updater keeps you on the active testing channel as new builds are released.

PAI is an autonomous, local-first development system built to work across an entire project. It maps the codebase, plans the change, edits the right files, runs checks, diagnoses failures, repairs them, and verifies the result before calling the work complete.

Early access
PAI is ready for real testers.
The current Developer Alpha is public. Alpha 9 is in final release-candidate validation, and feedback from real projects is what determines what gets fixed and hardened next.
02
Break it on something real
Give PAI actual coding, debugging, refactoring, or project-wide work. The most useful feedback comes from places where the system gets confused, stalls, or fails verification.
03
Help shape the next build
Join the Discord for release announcements, tester discussion, bug reports, suggestions, development previews, and the fastest path back to the project.

The target is a coding system you can hand real work to—not a chat box that stops at “here’s some code.”
Understand before changing
PAI maps the project, languages, frameworks, requirements, dependencies, and cross-file contracts before deciding what needs to move.
Make the work real
It creates and edits files, follows the project’s existing structure, and keeps the requested scope connected to actual implementation.
Prove the result
Builds, tests, deterministic checks, and repair passes give PAI evidence that the request is complete before it calls the task finished.
Built for serious work
One system. The whole job.
PAI combines project understanding, coding, verification, local model execution, and recovery into one desktop workflow.
Give PAI a goal, not a file-by-file checklist.
PAI is designed to determine which files matter, preserve surrounding behavior, make bounded changes, and keep moving until the work reaches a verified outcome.

Your coding model can run on your machine.
PAI-Coder ships as a native local runtime with CPU fallback and CUDA acceleration where supported, reducing setup friction and keeping local development local.

“Looks right” is not a completion condition.
PAI uses compiler output, tests, runtime evidence, requirement checks, and project contracts to decide whether a change can actually be accepted.
Autonomy without careless destruction.
Checkpointing, bounded repair, update rollback, preserved originals, and explicit outcome states are part of the architecture—not cleanup added later.

The model is a worker.
PAI is the system.
PAI is designed to stay model-independent. The application owns project understanding, planning, editing, execution, verification, recovery, and the user experience while coding models do the language work inside that system.
