Voice Note → LinkedIn Post with Apple Shortcuts + ChatGPT (No Install, No Server)

You already own the tool

Writing a LinkedIn post is a tax on busy people: the idea takes ten seconds, the writing takes thirty minutes. This flips it — you ramble into your phone for half a minute and a finished post lands on your clipboard. The best part: Apple Shortcuts is already on your iPhone and Mac, it's free, and there's nothing to install. No server, no monthly subscription, no new account, which is the trade against the hands-off n8n and Claude version of this workflow.

Three moves, one tap

The whole thing is a single Shortcut that stacks three small actions. It turns your speech into text, hands that text to AI with a "make this a LinkedIn post" instruction, then drops the polished post on your clipboard. You fire it from the Share Sheet or your Home Screen with one tap. The mental model: talk, tap, paste.

What you'll need

Just two things, and you likely have both already:

• A Mac or iPhone — open the pre-installed Shortcuts app.
• One AI step — either Apple Intelligence's free on-device "Use Model" action, or the free ChatGPT app, which adds a ChatGPT action you can drop right in.

Apple Intelligence keeps everything on-device. ChatGPT often writes a touch more naturally. Either works fine.

Start a blank Shortcut

Open Shortcuts and tap the + to start a new one. Name it something you'll spot on your Home Screen, like "Voice → LinkedIn." You're now looking at an empty canvas where each action stacks on the last, top to bottom — and that order is the workflow. Don't overthink it. You'll add just four small actions, one at a time.

Turn speech into text

Add a Dictate Text action. It transcribes your voice on-device, no internet needed. Tap the mic, talk for thirty seconds, and your words become text. Want to run it on a voice memo you already recorded instead? Swap in Get Text from Input so it works from the Share Sheet. Either way, you now hold the raw transcript — the raw material for the next step.

Hand it to the AI

Add your AI action and feed it the transcript. With Apple Intelligence that's Use Model; with ChatGPT it's the ChatGPT action. The prompt is what turns rambling into a post. Paste this and put the transcript variable at the very end:

Turn this voice note into one LinkedIn post: a strong one-line hook,
short punchy lines, one clear takeaway, no hashtags. Match the voice in
these examples of my posts: [paste 2-3 of your real posts]. Voice note:

Drop it on your clipboard

Add a Copy to Clipboard action and feed it the AI output. Now the finished post is sitting on your clipboard, ready to paste into LinkedIn. Want to eyeball it first? Add a Show Result action just before it so the draft pops up on screen. A three-second human glance catches the rare odd line and keeps every post sounding like you, not a robot.

Make it one tap

Open the Shortcut's settings (the toggle icon) and turn on Show in Share Sheet and Add to Home Screen. Now it lives one tap away: run it on selected text, on a voice memo you share to it, or straight from your Home Screen icon. That's the whole magic — the gap between "I have an idea" and "it's posted" basically disappears.

Make it yours

A few tweaks turn this from a trick into a habit:

• More formats: duplicate the AI action with a second prompt for an X post or an Instagram caption — one voice note becomes three.
• A daily nudge: add a Shortcuts Automation that pings you each morning to record one idea, the same scheduling trick behind the end-of-day shutdown shortcut.
• Fully on-device: prefer not to connect ChatGPT at all? The built-in Use Model action keeps everything local and free.

Your first step

Open Shortcuts, tap +, and add just two actions: Dictate Text, then Show Result. Run it and talk for ten seconds. Seeing your own words appear as text proves the hard part works — the AI and clipboard steps take two more minutes to bolt on.

Try this now

Record a two-minute voice note on the thing you explained at work this week, run it through the shortcut, and read the draft out loud. Edit it, post it or bin it — but you will know the pipeline works before you invest another minute.
