Independent software for the Mac
Local-first.
AI-ready.
Two tools that keep your data on your Mac and connect it to the AI agents you already use — a plan your agents can read, and secrets they can use without ever seeing the values.
The tools
One family, two jobs.
Both are native macOS apps, both are local-first, and both ship an MCP server so AI coding tools work alongside you — without your data leaving the machine.
Project planning
Kaido Plan
$9.99/ year
A planning workbench for AI coding agents. Turn requirements into a WBS, put dependencies on a timeline, and keep execution in sync — in one plan people and AI can inspect.

Bitcoffer
$9.99one-time
A local-first password manager. Credentials never leave the device, and an MCP server hands them to AI agents without ever returning the secret values to the model.

What these tools share.
Local-first
Your data stays on your Mac. No account, no cloud sync, no telemetry. Verifiable, not just promised.
Built for AI agents
Every tool ships an MCP server, so Claude Code, Codex and CodeBuddy can read and act — without the values leaking into the model.
Native macOS
SwiftUI front ends, App Sandbox, Touch ID where it matters. Built for the Mac, not a web app in a wrapper.
One person, careful software.
Independent software, designed, built and documented with care. Both tools are proprietary and local-first — your data stays on your machine.
