I build MightyMouse. These are the things I have worked out along the way.

I make MightyMouse, a Mac app that pairs your iPhone to your computer as a trackpad and a microphone, and transcribes what you say on your own machine instead of sending it to a server.

Everything on this blog comes out of building that. When something surprises me, or takes me a week to work out, I write it down here so the next person spends an afternoon on it instead.

I write these myself and I check the claims against the code before they go up. If something here is wrong, I would genuinely like to know.

Everything I have written

• Every AI model and service in one account Building something with AI usually means signing up for six tools, pasting keys into five of them, and losing an afternoon before anything works.
• MightyMouse vs Lovable Both let you describe what you want and get software back. The difference is where the result lives and what happens when you outgrow it.
• MightyMouse vs Codex cloud A cloud coding agent works while you are away from your desk. The question is what else comes with it, and what you give up.
• MightyMouse vs ChatGPT Plus The $20 subscription most people already have is ChatGPT. Here is what the same money buys somewhere else, and what you would miss.
• How to build an iOS app without a Mac Most guides say you need a Mac to make an iPhone app. For the writing part and the build part, you do not.
• Control your Mac from your iPhone People search "control mac from iphone" wanting four different things: see the whole screen from across the world, a trackpad in the same room, Apple's own accessibility tool, or something in between. Here is which one is actually yours.
• Use your iPhone as a trackpad for your Mac Your Mac trackpad just died, or you are three feet from your desk and do not want to walk over. Your iPhone is right there. Apple gives you no way to use it as a trackpad.
• Use your iPhone as a keyboard for Mac You want to type on your Mac from across the room, and your iPhone is right there in your hand.
• Use your iPhone as a microphone for your Mac Your Mac has a mic, or it does not, and either way "use my iPhone as a mic" can mean two different things.
• Mac dictation not working, fixed You hold the key, you talk, and nothing appears. Or it worked yesterday and stopped today. The fix depends on which one is actually happening.
• The best dictation app for Mac Every "best dictation app" list gives you one winner. The honest answer depends on what you are trying to do.
• Speech to text on your Mac Mac has had speech to text built in for years, but the setup screen does not tell you the shortcut, which voice commands are real, or where your words actually go.
• Claude Code on iPhone Search "claude code on iphone" and you get a pile of guides for third-party tools, most written before Anthropic shipped its own answer.
• Codex from your phone You start Codex on something and walk away from your desk. Then you want to check on it, or answer its one question, from your phone.
• Cursor from your phone You want to check on a Cursor agent, or keep it going, without sitting at your desk. The first question is whether Cursor even has a phone app for that.
• Connect Ray-Ban Meta to a laptop Ray-Ban Meta glasses are built to pair with your phone. Whether they pair with the laptop sitting next to it is a different question, and the answer depends on what you are trying to do with them once connected.
• Use OpenClaw from your phone OpenClaw answers you in WhatsApp or Telegram. It still runs on your Mac, and the moment it needs something only your Mac has, your phone is stuck outside.
• Use Hermes Agent from your phone Hermes Agent remembers what it learns. It does not, yet, have a way to reach you when you are not at the keyboard.
• Check on Paperclip from your phone Paperclip does not run continuously. It wakes on a schedule, does a batch of work, and goes quiet again - often while you are nowhere near your Mac.
• Run any terminal AI agent from your phone Every few weeks a new AI agent launches that runs on your own machine instead of someone else's server. Every single one has the same gap: no phone app.
• Approve an agent from your lock screen An agent that stops to ask you something is not slow. It is just waiting for a person who is not there yet.
• Dictate anywhere on your Mac Talking is about three times faster than typing. The catch has always been where your voice goes to become text.
• Run coding agents from your phone The problem with a coding agent is not that it is slow. It is that it stops, and you are not at the desk.
• Why dictation breaks over SSH It works in Mail. It works in Slack. You SSH into a server, start talking, and nothing arrives.
• Hands-free dictation on your Mac Push-to-talk dictation has a hidden requirement: a hand free to hold the key down. The moment your hands are full, or you are pacing around thinking out loud, that requirement is the whole problem.
• Use Meta Ray-Ban Display with your Mac Out of the box the glasses talk to your phone, not your computer. That is the gap this closes.
• Sidecar for iPhone The short answer is no, and no setting will change it. The longer answer is that the thing people actually want is still possible.

MightyMouse turns your iPhone into a trackpad and microphone for your Mac, and transcribes your voice on your own machine.
