UseIt StudioReview: a box you can print from a sentence

zCAD AI turns a written description into a 3D part you can open and edit in CAD. Describe it the way you'd brief a colleague, with real numbers: an L-shaped bracket with a 60 mm upright, a 50 mm base, 5 mm thick, and a 6 mm hole through each leg. Add a reference image if you have one. You get proper geometry back, not a picture. It handles assemblies too, and the examples run from gears and pulleys up to a drone frame of about 14 parts. Every plan exports STEP, the file other CAD programs open. Once the AI gets you close, you keep refining the model in zCAD Online, the company's full editor. Free gives you 200 credits a month plus a one-time 600-credit beta bonus, but free models are public, used for training, and limited to non-commercial work. Plus, at $49.99 a month, makes your models private and lets you use them commercially. Pro, at $89.99, adds drawings and full editing in Online.

Cuey is a Chrome extension that sits next to your chat and asks the other AI models the same question. Ask ChatGPT something and Cuey's panel pulls in answers from Gemini and Claude, each on its own tab. Then it writes an Enhanced Answer that tells you when another model got it right and yours didn't. On Cuey's own site, ChatGPT suggests walking to a car wash fifty meters away. Cuey points out that you'll want to bring the car. It also carries memory between assistants, so what you told one model comes along when you ask the others. Free gets you five comparisons a day across ChatGPT, Claude, Gemini, DeepSeek and Grok, with replies side by side that you can save. Pro is $18.99 a month for 25 a day, 500 MB of files and export. It only works in Chrome, and there's no separate app.

IrisGo is a desktop assistant for people who run a business on their own. At 8 every morning it reads your calendar and unread email and sends you a short brief in chat. In the demo, that's three priorities, two client calls, and an Adobe invoice due today. From there it triages your inbox and picks up the rest of the day's admin. The headline trick is Watch & Learn: you do a task once while IrisGo watches, and after that it can repeat the steps for you. It runs on Windows 11 (64-bit) and Apple Silicon Macs. There's no version for Intel Macs or phones. The beta is free and updates itself, and IrisGo only sees the data and workflows you give it permission to see. The company is backed by Andrew Ng's AI Fund, but it hasn't said what IrisGo will cost once the beta ends. Don't confuse it with Iris, the agent you text from iMessage.

Cue by Manus gives you personal AI agents for everyday life admin, each with its own email address, phone number, wallet and computer. It's meant for busy professionals and families who want to hand off bookings, appointments, reminders and follow-ups. You create an agent in the app, or by scanning a QR code, and set permissions for what it may do on its own. From there you can forward calls to it, let it send emails and make payments, and it keeps working on a task after you log off. Several agents can work together in one group chat. Right now you need an invite code to get in.
