Brad Dunlap · apps, AI video & motion

A one-person lab for apps, AI video, motion graphics, and visual design. I'm also into home automation, and I build small robots and 3D prints and write up how they work.

Apps

Two apps I build and use myself. Both are free, open source, and out now.

macOS

PulseCanvas Studio

Free · Open source · Available now

Turn a song into a music-synced video.

Drop in a soundtrack and PulseCanvas finds the beat, splits the song into sections, and plays visuals in time with the music: 31 visualizers of its own plus 7,838 MilkDrop effects. Shape the colors and motion, then export an MP4 in wide, portrait, phone, or square formats, up to 4K at 60 frames per second.

Jotley

Free · Open source · Available now

Talk, or play anything, and get a transcript and a summary, all on your device.

Jotley is built on Apple Intelligence and made to work offline, so recording, transcription, and summaries all run locally with no internet connection. On a Mac it can listen to audio from any app, like a call or a video. On iPhone and iPad it records your voice.

Your notes are yours. Audio and transcripts are never sent to us or to any cloud AI, and nothing is stored on our servers. Your notes stay on your device and in your own iCloud.

About

I'm Brad Dunlap, an engineer in Florida.

By day I'm a principal engineer at Launch by NTT Data. Protomota is where everything else happens: the apps and videos above, small robots on the living room floor, simulations of those robots, home automation around the house, and whatever is on the 3D printer this week.

I try to automate as much of my day-to-day as I can with AI SI. My robots are all small ones for now, but I'd like a real one around the house someday.

Want more information?

Questions about an app, a video, a build, or anything else on this page. Send a note and I'll reply by email.

Open to business opportunities as well.

A coffee for the next build?

If something here was useful, or just fun to watch, you can buy me a coffee to help keep it going.

Tips are optional. Jotley and PulseCanvas stay free and open source.
