Demo: a rough email draft in Mail is selected, PhaseType is opened with Command Shift Space, asked to “Fix it and make it warmer”, and the polished result is pasted back over the draft.

How it works

Three keystrokes from rough to ready

PhaseType sits quietly in your menu bar. It steps in when you call it and hands control straight back.

  1. i cant make thursdays sync, can we moved it?

    01

    Select

    Highlight text in Mail, Slack, Notes, your browser, your editor, or pick files in Finder. If you can select it, PhaseType can read it.

  2. ⌘⇧Space

    02

    Press

    Your hotkey opens a small panel over the app you are in. Ask for anything, tap Fix the sentence, or pick a preset.

    Pasted

    03

    Paste

    The result streams in. Paste it over your selection or copy it, and your clipboard stays exactly as it was.

Two hotkeys

One to ask. One to fix.

Open the panel when you want to steer the rewrite. Use quick fix when you just want it right, without leaving the line you are on.

Features

Everything for writing, nothing in the way

Built around one idea: you should never have to leave the thing you are writing.

  • Works in every Mac app

    Mail, Slack, Notion, Xcode, a form in your browser. PhaseType reads your selection through macOS Accessibility, so there is nothing to install per app.

    • Fixed 4 typos · just now

      Mail · Re: Thursday launch sync

    • Wrote the summary · 2m ago

    • Translated to Spanish · 9m ago

      Safari · Support form

  • A conversation, not a one-shot

    Results stream in as they are written. Not quite right? Reply, and it refines with the whole thread in mind.

  • Writes from nothing

    With nothing selected, describe what you need and it pastes at your cursor.

  • Presets for every voice

    Save how you write a Slack reply or a client email, plus a few facts about you. Press ⌘P in the panel to apply one.

    ⌘P Choose a preset

  • Your clipboard, untouched

    Where apps allow it, PhaseType reads and replaces text directly. Elsewhere it borrows the clipboard and puts it back.

  • Lives in the menu bar

    No dock icon, no window to manage. Optionally opens at login.

  • Hotkeys you choose

    Record any shortcut. PhaseType checks that no other app is already using it.

    Click a shortcut and press your own.

  • Any model, every cent counted

    Pick any chat model your key can use. Settings shows the tokens and estimated cost of each request, kept only on your Mac.

    • gpt-5-mini

      142 requests

      $0.00

    • gpt-4o-mini-transcribe

      2 recordings

      $0.00

    • gpt-4.1

Privacy

Your key. Your Mac. Your words.

No account, no PhaseType cloud, no copy of your text or files sitting on someone else's server.

FAQ

Questions, answered

Anything else? The app's Settings explain each option in plain words.

  • What is PhaseType?

    PhaseType is an AI writing assistant for macOS. Select text in any app, press a hotkey, and fix or rewrite it with AI. Then paste the result straight back over your selection, or copy it. Select files in Finder instead and you can ask about them.

  • Which apps does it work with?

    Any app where you can select text: Mail, Slack, Notes, Messages, Notion, your browser, your code editor and more. PhaseType reads and replaces your selection directly through macOS Accessibility, and falls back to copy and paste in apps that don’t support it, so apps need no special support.

  • Can it read files, recordings and videos?

    Yes. Select up to five files in Finder and press the panel hotkey. PhaseType reads PDFs, Word and other documents, images, text and code. Audio is transcribed, and for video it transcribes the sound and looks at frames from the picture. Recordings can be up to two hours long.

  • What are presets?

    Saved writing styles, like “Slack reply” or “Email reply”. Each one holds instructions for tone and structure, plus optional facts about you, such as your name and role. Press ⌘P in the panel to apply one. Create, edit or turn them off in Settings.

  • Do I need an OpenAI API key?

    Yes. PhaseType uses your own OpenAI API key, and usage is billed to your OpenAI account. It lists the chat models your key can use and picks a fast default, which you can change in Settings.

  • How much does it cost to use?

    You pay OpenAI their usual prices for what you use. Settings › Usage shows the tokens and an estimated cost for every request, with totals by model, so there are no surprises. Your OpenAI dashboard has the exact bill.

  • Where does my text go?

    Only to OpenAI, directly from your Mac, along with any files you attach. There are no PhaseType servers in between and no account to sign up for. Your API key is stored encrypted with the macOS Keychain, and your request history stays in a file on your Mac that you can clear any time.

  • Why does PhaseType need Accessibility access?

    macOS requires Accessibility permission before one app can read or change text in another. PhaseType uses it only to read your selection and put the result back, directly or with copy and paste keystrokes.

  • What is the difference between the panel and quick fix?

    The panel (⌘⇧Space by default) lets you type any instruction, attach files, apply a preset and keep refining before you paste. Quick fix (⌥⇧Space by default) fixes spelling, grammar and punctuation and pastes it back immediately, without opening anything.

  • Can I change the hotkeys?

    Yes. Record any shortcut during setup or later in Settings. PhaseType checks that no other app already uses it.

  • Which Macs are supported?

    Both Apple Silicon (M1 and later) and Intel Macs. Each has its own download, so pick the one that matches your Mac.

  • macOS says it “could not verify PhaseType”. Is that normal?

    For now, yes. Early builds are not notarized by Apple yet. Right-click PhaseType in Applications, choose Open, then Open again. You only need to do this once.
