An AI coding agent for Xcode that writes Swift, runs builds, fixes build errors automatically and shows diffs, while source code stays on your Mac.

Automatic Build Error Repair: Runs the Xcode build, identifies compile errors, applies fixes and re-validates the result through an iterative repair loop until the project compiles.
Side-by-Side Xcode Workflow: Sits next to Xcode with real-time build monitoring, diff review and inline approvals so you never leave the IDE to consult an AI.
Codebase Understanding Before Coding: Reads and understands the project structure before writing anything, so generated Swift fits the existing architecture rather than being pasted in blind.
Diff Review Before Apply: Every proposed change is shown as a reviewable diff that you approve or reject, so the agent never silently rewrites files.
Persistent Project Memory: Retains its understanding of your project across development sessions instead of relearning the codebase every time you start.
Local Source Code Storage: Source code stays on the Mac under a privacy-first architecture, with only inference context sent off-device.
Swift and SwiftUI Native: Built for the Apple ecosystem with deep Swift and SwiftUI understanding and native Xcode workflows rather than generic language support.
Usage-Based Credits: Pay per AI request with exact credit costs shown before and after every task, with no seats or subscription commitment.

Feature Implementation: Describe a new screen or capability in plain English and have the agent write the Swift, build it and hand back a reviewable diff.
Build Failure Triage: Hand a failing Xcode build to the agent and let it iterate through compile errors until the project builds again.
Legacy UIKit Modernization: Refactor older Apple codebases toward SwiftUI and current Swift idioms with the agent validating each step against a real build.
Privacy-Constrained Teams: Adopt an AI coding agent at organizations that cannot upload source to the cloud, since the code stays on the developer's Mac.
Occasional Contract Work: Pay only for the requests you actually make, which suits indie and contract Apple developers who do not want a monthly seat.
Code Change Auditing: Use the mandatory diff review step to keep tight control over exactly how AI modifies an app before release.

Rosply is an AI desktop agent that automates repetitive Windows tasks by viewing the screen and controlling mouse and keyboard like a human.

Vision-Based Control: Takes a screenshot every step and reads dialogs, popups, and dynamic UI like a human, with no DOM scraping or XPath required.
Cross-Application Automation: Controls Chrome, Excel, VS Code, and legacy enterprise software—anything that runs on the desktop—without plugins.
Instant Halt Control: Press Ctrl+H at any moment to immediately stop the agent, or close the terminal window for a clean exit.
Multi-Platform Support: Fully tested on Windows 10/11, supported on Linux, and functional in beta on macOS, with mouse, keyboard, and screenshot control on all.
Model-Agnostic via OpenRouter: Sends only screenshots and task text to OpenRouter, letting you pick the underlying AI model.

Repetitive Data Entry: Automating form-filling and data transfer across desktop apps without scripting.
Legacy Software Operation: Driving old enterprise tools that lack APIs by interacting through the visible UI.
Spreadsheet Workflows: Performing multi-step Excel tasks autonomously from a plain-text instruction.
Browser Automation: Navigating and completing tasks in Chrome the way a person would.
