ArcLight — Turn slides into live video on your Mac

Live video, built like a slide deck. ArcLight is the Mac app that turns slides into live video.

Cameras, screens and titles on slides — live in Zoom, recorded or streamed.

Free for 30 days, then $49/year — launch price, locked in.

A complete editor for live shows.

Layout, type, style and motion — with the controls you already know from Keynote and PowerPoint.

A transition on every slide. Magic Move, dissolves, wipes and stingers — each with a live preview as you choose.

Snap into place. Guides appear as edges and centers line up with the slide and with each other.

Cameras that glide. Magic Move keeps the same camera across slides and moves it to its new place — on air.

Builds with a click. Bring each layer in on your cue — fade, scale, fly or type on, word by word.

Magic Move, for live cameras.

Every scene is a slide. Press → and your cameras glide to their next place — live.

Your AI is the co-host.

ArcLight is built AI-first. It speaks MCP, so Claude — or any MCP client — can build slides, write the script, take the next slide and watch the program with you. Every change it makes is outlined on the canvas and one Undo away.

Sixteen effects at once. Not a beat missed.

Film looks, bloom, vignette, bokeh, halftone — stack sixteen or more on live cameras and ArcLight keeps every one in real time, on Metal.

Built for the Mac.

Big on performance. Easy on your fans. Native Swift on Metal — no browser engine, no cloud.

-42%
of your Mac's CPU to run a seven-slide show with a live camera. Your fans stay quiet. -84%
of the GPU for the whole program, previews included.

Every kind of show.

Made for people who present — on a stage, in a class, on a call or on their own channel.

Presenter view

The show full screen on the projector while your script, the next slide and the clock stay on your laptop.

Notch teleprompter

Read the lesson and keep eye contact — cues put the next slide up for you.

ArcLight Camera

Your screen and your face arrive together, in any customer’s Zoom or Teams.

Magic Move + recording

Glide between scenes live, and record the program as a finished .mov.

Everything live, on one canvas.

Every camera you own

Built-in, USB or your iPhone — one pipeline per camera, shared by every slide.

Titles that build

Lower thirds and name straps animate in on your click.

Video with alpha

Loop, play once, play and hide.

Look like you hired a colorist.

Grade each camera once and it matches on every slide — with the scopes a colorist would use. Waveform, RGB Parade, Vectorscope, Histogram.

Your script, under the lens.

The teleprompter docks beneath your Mac's notch, so your eyes stay on the lens. Write cues into the script and the show follows your words: reach ▸ Interview, and the interview goes live.

Go live everywhere.

One program, sent wherever your audience is: stream it over RTMP, put it in Zoom as your camera, record it and show it on a projector — all at once.

Share your screen without disappearing.

In Zoom, Teams, Meet or Webex, ArcLight is simply your camera. Your screen, your slides and you arrive as one clear picture — for a client demo, a class or the Monday update.

A note from the maker

“Every video, presentation, or live show meant juggling scene software and a slide deck. ArcLight is the tool I wanted: build it like a deck, then press play.”
