It's a practical option for developers who want to add powerful generative media features without a lot of extra complexity.

Ravioli

Create custom stamp shapes

Ravioli is a small but powerful design tool for making custom postage-stamp shapes. You pick a shape, then tweak the stamp size, the perforation holes, and the roundness of the edges. When you're happy, export it as a transparent PNG or a scalable SVG. Perfect for adding a unique touch to your designs or creating custom stickers.

Notchling

A little creature that lives in your MacBook notch

Notchling is a delightful little creature that lives right in your MacBook's notch. It keeps an eye on your cursor, nods off when you're idle, and reacts to your battery level. Drag a file toward it, and it'll open its mouth and carry the file for you. It's completely free, takes up less than a megabyte, and all processing stays on your Mac, so your data never leaves your device.

Stitch AI by Dynamic Mockups

The first embroidery digitizing agent

Stitch analyzes your artwork like an experienced digitizer, carefully planning stitch direction, density, and pull compensation for each area. In just 15 seconds, it generates everything you need: a machine file, a production sheet, stitch count, and a lifestyle mockup preview to show your client. This saves you hours of manual digitizing work and ensures professional quality every time.

PostBox

Stage and post designs from your mac

PostBox turns your MacBook notch into a drag-and-drop posting tool for your work. Drag an export in, write the caption once, and publish to X, Bluesky, Threads, LinkedIn, Dribbble, Instagram, Pinterest, Behance, and Cosmos all at once.

Bloop

Turn any Mac audio into a visual you can actually export

Bloop turns system audio or mic input into eight real-time shader skins. Every frame reacts to what's actually playing. Keep it beside your work in the resizable Mini Player or send it to the menu bar. Drop in an MP3 playlist and export the whole thing as a finished video. It runs on Apple Silicon, is notarized, and has no subscription. Two skins are free forever, and they're the full app, not a trial.

Modeinspect

99 Days Free AI Credits - Design product UI in your codebase

Most software gets designed twice: first as a picture, then again in code. That's where the intent gets lost. Modeinspect is an AI-powered design canvas that lets you work with the real thing from the start. Connect your codebase, open an existing screen, and design using your actual components, tokens, live data, states, and breakpoints. You can explore variations with AI, keep the details that matter, and when you're ready, publish your changes live or send them to engineering for review. You stay in control of when things go live. The canvas isn't the destination; the product is. Modeinspect bridges the gap between design and development, so what you see is truly what you get.
