The projector sewing landscape has been changing fast over the past several years. In my last video, I introduced three phone-based options for projector sewing. Today, I’m dedicating an entire post to one of them: IntelliSew.
Whether you’re already using IntelliSew and want to get more out of it, or you’re still trying to figure out which app is right for your setup, this one’s for you. I’ll be honest — there were a couple of things it does that I didn’t expect. By the end, you’ll know exactly whether this app belongs in your projector sewing workflow.
Watch this on YouTube! I tried IntelliSew for Projector Sewing, My Honest Take!
Where IntelliSew Came From
IntelliSew was created by Saad, whose wife Teresa ran into a couple of frustrations when she started projector sewing. Pattern Projector worked well on her computer, but not so well on her phone. On top of that, calibration became a repeated annoyance — someone (or the cat) would inevitably bump the projector, and she’d have to recalibrate all over again.
Saad built IntelliSew as a personal project to solve those two problems. He kept adding features as his wife needed them, and eventually she suggested the app could help other sewists too — so they decided to release it.
Getting Started: Availability and Pricing
IntelliSew is currently available for iPhone and iPad through the App Store. It is not yet available for Android.
The basic features are free, with an optional Pro subscription for more advanced tools. The app description in the App Store lays out exactly what’s included free versus what requires the upgrade.
One notable detail: AI calibration is currently free during its beta period, while the developers refine the feature. Keep in mind that in the future, this may move behind the Pro subscription.
Projector Sewing Calibration: Four-Corner vs. AI
From the home screen, you’ll tap Calibrate and choose between two methods: four-corner calibration or AI calibration.
Four-corner calibration works by dragging a target to match the size of your mat, then measuring from there — similar to the drag-and-drop calibration you may already know from Pattern Projector.
AI calibration is the newer, more experimental option. You select your mat size (for example, half-inch squares), make sure your mat is visible within the frame, and the app attempts to recognize it and calibrate automatically.
In testing, results were mixed. On a larger mat, the first AI calibration attempt needed some refining — the app can capture a large image relative to the mat, so you may need to adjust the length, height, and corners manually afterward. On a smaller mat, the AI calibration came very close to accurate right away, needing only a slight tweak to one corner.
So is AI calibration actually faster than four-corner calibration? Honestly, it varied. Sometimes it worked beautifully on the first try with no adjustments needed. Other times, it took about as much fine-tuning as manual calibration would have. It’s a promising beta feature, but not yet a guaranteed shortcut — and it’s worth trying both methods to see which works best with your particular mat and setup.
Navigating the Interface
Once you’re calibrated, you can open a new pattern or pick up a recently opened one right where you left off — the app remembers your position. Navigation within a pattern uses two-finger gestures.
To bring up the main menu, a single tap on the screen does the trick, revealing a circular menu of tools. If you’re ever unsure what something does, there’s a built-in question mark button that explains each menu item.
Here’s a rundown of what you’ll find as you work your way around that circular menu:
- Line thickness — adjust from a slider, measured in pixels, affecting both pattern lines and text.
- Line and background color — fully customizable, not just limited to the standard black or white. You can use color sliders to dial in something that works best against your fabric, and save custom color combinations with a tap of the plus button. A few presets (like neon green on black) are already built in.
- Layers — toggle pattern layers on or off, select all or none, and choose just the size you need. Don’t forget to keep your text layer switched on.
- Zoom and rotate — rotate your pattern in 90-degree increments by default. Changing to custom degree increments (like 45 degrees, handy for cutting on the bias) is a Pro feature. The zoom control turns red any time you’re not at 100% zoom — a nice visual reminder not to start cutting while zoomed in.
- Flip — horizontal and vertical flip, with a red highlight showing when either is active.
- Move — nudge your pattern slightly, useful for small lengthening or shortening adjustments.
- Thickness recalibration — adjusts your calibration grid to account for thicker fabrics or multiple layers, which is especially useful if you’re using an ultra-short-throw projector where thickness can visibly shift the projection.
- Quick Look — lets you pan around the pattern to check something (like reading small text or instructions) without losing your place. Release it, and the view snaps right back to where you were cutting.
- Annotations — a long press lets you mark pieces as cut, so you can keep track of your progress as you go. Combine this with Quick Look to glance over your pattern and see exactly what’s left to cut.
When you’re ready to close out and start a new pattern, a single tap brings up the main menu, and a long press on the return icon takes you back to the home screen. And if the menu is ever in your way while you work, a single tap makes it disappear — tap again, and it’s back.
Free vs. Pro Features
Core functionality in IntelliSew mirrors what Pattern Projector offers, and that core experience is free. The Pro subscription unlocks the more advanced extras, including:
- Cut-tracking checkmarks (annotations)
- Quick Look mode
- Custom rotation increments beyond 90 degrees
- Fabric thickness adjustment mode
The developers have said they’d like to make IntelliSew development a full-time endeavor, which is the reasoning behind the subscription model for these added features. As always, you can check their website for the current list of paid features, and try the free version first to decide whether Pro is worth it for your workflow.
What’s Next for IntelliSew
I asked Saad where he sees IntelliSew heading. High on the wishlist is pattern manipulation built directly into the app — eliminating the back-and-forth between programs like Affinity or Inkscape and the projection screen itself. That could include selecting and dragging individual pieces to rotate, duplicate, or flip them, and even arranging pattern pieces like a layout puzzle directly in the app.
Longer term, the team hopes to add basic pattern adjustments such as changing seam allowance, lengthening or shortening pieces, adjusting curves like the neckline shape, and adding notches, buttons, or buttonholes. All of this is still in development, and they’re actively looking for community input — they have a subreddit linked below where you can add suggestions, plus an email if you’d like to reach out directly.
My Takeaway IntelliSew Review
After spending real time with IntelliSew, here’s where I land: this app is genuinely well thought out. You can tell it was designed with input from people who actually sew — the workflow feels intuitive, and the interface is polished rather than an afterthought. The focus on phone-based projection means it’s specifically optimized for sewists who want to work that way.
That said, unlocking everything IntelliSew offers requires a subscription, so it’s worth weighing whether those extra features justify the cost for your setup and how often you sew. If a subscription isn’t for you, Pattern Projector is still out there — free, open-source, and a genuinely solid option. There’s no shame in sticking with what works.
Ultimately, IntelliSew is a great choice if you want a premium, purpose-built experience on your phone. It’s one of the most polished projector sewing apps I’ve used — though right now, it’s only available on iPhone (or iPad) through the App Store.
If this helped you figure out which direction to go, I’d love to hear about it. And if you’re new to projector sewing and want to go deeper, check out my other resources to get started.
Happy sewing!
