Infrastructure for AI sales agents on Instagram, WhatsApp and other DM channels, built and improved by talking to an LLM over MCP.

MCP Server Control Surface: Exposes agent creation, testing, analysis and improvement as MCP tools, so Claude, Claude Code, Codex or ChatGPT becomes the interface instead of a dashboard.
Cortex Playbook Library: Ships prompt templates, KPI rubrics and anti-patterns distilled from agents that ran in production, so a new agent inherits patterns that already converted rather than starting blank.
Multi-Channel DM Deployment: Connects agents to Instagram, WhatsApp and other direct-message channels where the selling actually happens, without a separate build per channel.
Versioned Changes with Rollback: Every edit to an agent is versioned and instantly reversible, so a bad prompt change during a live launch can be undone rather than debugged under pressure.
Synthetic Conversation Testing: Runs an agent against generated conversations before it reaches a real inbox, surfacing broken qualification logic ahead of launch.
Follow-Ups and Keyword Triggers: Fires scheduled follow-up sequences and keyword-based branches so stalled conversations get reopened automatically.
Built-In CRM and Funnel Analytics: Ninjo Studio provides real-time conversation views, contact records and funnel reporting in one panel for when you want direct oversight.
Payment Recovery Flows: Agents can chase declined payments conversation by conversation, a pattern the team credits for recovering 47 declined payments in a single four-day launch.

Creator and Coach Launches: Running a short high-volume launch where an agent qualifies inbound DMs, handles objections and sends payment links at a pace a human team cannot match.
Instagram Lead Qualification: Filtering hundreds of daily inbound Instagram messages down to the prospects worth a human sales call.
WhatsApp Sales Follow-Up: Reopening conversations that went quiet with timed follow-up sequences instead of leaving them to decay.
Agency Multi-Client Operations: Managing many client agents from a chat interface so a three or four person team can operate over a hundred agents.
Declined Payment Recovery: Having an agent work through failed transactions individually to recover revenue that would otherwise be written off.
Rapid Agent Iteration: Rewriting an agent's qualification logic mid-campaign and rolling back immediately if conversion drops.

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.
