I used to have a folder on my iPhone home screen with 18 text shortcuts. Translate clipboard. Fix grammar. Make professional. Convert to bullet points. Strip formatting. Add to notes. Each one built by hand in the Shortcuts app, each one doing exactly one thing.

Then I tried using AI keyboard actions for the same tasks. After a month of using both side by side, the difference was clear — but not for the reason I expected.

The Test: Same Tasks, Two Methods

I tracked my text automation usage for four weeks. Every time I translated, reformatted, rewrote, or otherwise transformed text, I noted which method I used and how long it took.

The tasks I do most often:

Translate text (Spanish/Chinese to English)
Fix grammar before sending important emails
Rewrite casual messages in a professional tone
Summarize long emails or articles
Format rough notes into bullet points

Here’s what I found.

Speed: AI Keyboard Wins Every Time

The raw speed comparison wasn’t close.

Translating a paragraph (Spanish → English):

Shortcuts: Copy text → open share sheet → tap shortcut → wait → go back → paste. ~12 seconds.
AI keyboard: Select text → tap Translate → tap English → done. ~4 seconds.

Rewriting a message as professional:

Shortcuts: Copy text → home screen → tap shortcut → wait → go back → paste over original. ~15 seconds.
AI keyboard: Select text → tap Professional → text replaced inline. ~3 seconds.

Fixing grammar:

Shortcuts: Copy → run shortcut → paste. ~10 seconds.
AI keyboard: Select → Fix Grammar → done. ~3 seconds.

The pattern is obvious. Shortcuts require copy-switch-run-switch-paste. AI keyboard actions work inline. The app switching is what kills Shortcuts for quick text tasks. It’s not the processing time — it’s the context switching.

Over four weeks, I estimated the AI keyboard saved me about 8-10 minutes per day on text tasks. That’s roughly 4 hours per month. Not life-changing, but noticeable.

Reliability: AI Keyboard Wins Again

During the test month, three of my shortcuts broke. One stopped getting clipboard content after iOS 19.3.1 update. One started returning blank results intermittently. One crashed the Shortcuts app when processing text longer than about 2,000 characters.

Debugging took about 45 minutes total. I deleted and rebuilt two of them. The third I just gave up on.

The AI keyboard actions worked every time. Zero failures in a month. There’s nothing to break because there’s no chain of actions — you select text, pick a transformation, and the AI handles it.

This is the underrated advantage. Shortcuts are brittle because they’re chains of dependent steps. If step 3 of 6 fails, the whole thing fails. AI actions are single operations — there’s less to go wrong.

Flexibility: AI Keyboard Wins (With a Caveat)

With Shortcuts, I had exactly the transformations I’d built. If I needed something new — say, “rewrite this for a Twitter audience” — I had to build a new shortcut. That meant stopping what I was doing, opening Shortcuts, building and testing the workflow, then going back to my task. Minimum 10 minutes for a simple one.

With an AI keyboard, I can create a custom action in about 30 seconds. Type a prompt like “Rewrite for Twitter: concise, punchy, under 280 characters” and save it. Done. Or just type the instruction directly each time without saving it.

The caveat: Shortcuts can do things AI keyboards can’t. Multi-app workflows (save text AND create reminder AND send notification), scheduled automations (run every morning), and hardware triggers (run when I arrive at work). These are outside what any keyboard can do.

Quality: It Depends on the Task

For straightforward tasks — translate, fix grammar, change case — both produce identical results.

For nuanced tasks — rewrite for tone, summarize while keeping key details, format ambiguous text — the AI keyboard is better because it understands context. A Shortcuts workflow that “makes text professional” is really just a template with find-and-replace rules. An AI action that “makes text professional” actually understands what professional means in context.

Example: I fed both this casual message: “hey can u push the meeting back? something came up, kinda urgent”

Shortcuts version (template-based): “Hey, can you push the meeting back? Something came up, kind of urgent.” (Just expanded abbreviations.)

AI keyboard version: “Hi — would it be possible to reschedule our meeting? Something urgent has come up on my end. Happy to find another time that works for you.” (Actually professional.)

Cost: Shortcuts Win on Price

Shortcuts is free. You can build unlimited automations at no cost.

LudyType is $19.90 one-time. There’s a free tier with 70 lifetime actions so you can test it, and you can bring your own API key to use AI at cost.

If you’re optimizing purely on price and don’t mind the setup time, Shortcuts costs nothing. But if your time is worth more than about $5/hour, the setup and maintenance time of Shortcuts exceeds $19.90 within the first month.

When to Use Which

After a month of testing, here’s my framework:

Use Shortcuts When:

The workflow spans multiple apps. “Save this article to my Reading List AND create a reminder to read it.” Keyboards can’t orchestrate between apps.
You need scheduled or triggered automation. “Run this every morning at 8am.” “Run this when I connect to my car’s Bluetooth.” Keyboards are reactive, not proactive.
You want to process files, images, or non-text data. Shortcuts can resize images, convert file formats, create PDFs. Keyboards handle text.
You’re building a one-time workflow you’ll use rarely. Not worth installing a keyboard for something you do once a month.

Use AI Keyboard Actions When:

You’re transforming text you’re actively writing. Translation, rewriting, grammar fixing, summarizing. Anything where the input is text in a text field and the output is better text in the same field.
You do it multiple times a day. The 5-10 second time savings per action compounds fast.
The transformation requires understanding context. Tone adjustment, intelligent summarization, nuanced translation. These need AI, not rules.
You want zero maintenance. No building, no debugging, no fixing after updates.

Use Both:

Most power users will end up using both. Shortcuts for the complex, multi-app, scheduled stuff. AI keyboard for the quick, frequent, text-in-text-out stuff.

I went from 18 text shortcuts to 4. The remaining four do things keyboards genuinely can’t: one creates calendar events from text, one saves links to a specific Notion database, one runs a morning briefing automation, and one processes screenshots through OCR (though this one breaks regularly).

The other 14? All replaced by AI keyboard actions that work faster, more reliably, and without maintenance.

Try It Yourself

If you have a folder of text-related shortcuts on your home screen, try replacing one with an AI keyboard action for a week. The translation shortcut is the best first test — it’s the one where app-switching friction is most noticeable.

LudyType’s free tier gives you 70 actions, which is roughly two weeks of moderate use. Enough time to know if it replaces your shortcuts.
