An AI reels generator that makes the whole video
Most tools that call themselves an AI reels generator do one slice of the job: they add captions, or they find clips inside a long upload. OpenNolan's agent does the whole thing — from raw clips to a finished vertical cut.

The phrase covers a lot of very different tools, so it is worth being precise about what this one is. Caption tools take a clip you already cut and style the subtitles. Clipping tools take a long recording and find the moments worth posting. Template tools give you a look and ask you to fill it in.
All three assume the hard part is already done — that you have made the editorial decisions and just need help finishing. For someone whose job is not video, that is backwards. The hard part *is* the decisions: what to open on, where to cut, what proof to show, what to leave out.
OpenNolan's agent makes those decisions. You drop in your clips, or describe the video you want, and it assembles the whole vertical reel: pacing, captions, B-roll, images, music, sound effects and motion. Then you review it on a real timeline.
What the agent generates
The output is a finished 9:16 vertical video, not a draft or a storyboard. The agent builds the composition and places your clips, then fills in everything a reel needs to actually hold attention.
It opens on the payoff inside the first second, cuts every one to three seconds so attention keeps resetting, burns in captions because most of the feed watches on mute, and pulls supporting B-roll, images and screenshots from the web so the claim has proof behind it. It can also generate explainer animations, add avatar or talking-head segments with the background removed, and lay in music and sound effects.
- Hooks and fast cuts built on the short-form playbook
- Burned-in captions styled for mute viewing
- B-roll, images and screenshot proof sourced from the web
- Music and sound effects, keyframe animation, explainer animations
Generated is the first draft, not the last word
The agent carries the editing. You carry the judgment.
Fully automatic video tools tend to fail the same way: the output is plausible but slightly wrong, and there is nothing you can do about it. OpenNolan treats the agent's pass as a starting point rather than a verdict.
After it renders you get a real timeline — cuts, overlays, text, images, audio, transitions, crop, speed. Because the app renders once and edits cheap, most changes preview instantly without re-rendering, so disagreeing with the agent costs you seconds instead of another evening.
Runs on your Mac, with your own key
OpenNolan is a native macOS app. Your clips stay on your machine, rendering happens locally, and there is no account to create — which matters more than usual when the raw footage is you talking about a product that has not launched.
It is also bring-your-own-key: you add your own AI provider API key and pay those providers directly for the generation work, with no markup and no subscription. The app is open source. If you want the wider picture of how the app works, see what a Mac video editor run by an agent looks like.
- Native macOS app, local-first, no account required
- Bring your own key — pay providers directly, no subscription
- Open source
- Exports tuned for Instagram Reels, TikTok and YouTube Shorts
Frequently asked questions
Can I use this AI reels generator today?
Not yet. OpenNolan is in active development and this site is a waitlist — the Mac app has not shipped. Join the waitlist and we will email you when it is ready.
How is it different from a clipping tool like Opus Clip?
Clipping tools start from a long video you already recorded and find shorter moments inside it. OpenNolan starts from raw clips and builds a reel that did not exist yet. See the Opus Clip comparison for the detail.
Do I need to write a script or a prompt?
You can describe the video you want, or simply drop in your clips and let the agent work from what it sees. Either path ends at a finished vertical cut you can review and change.
Does it just add captions to my clip?
Captions are one part of it. The agent also decides the pacing and cuts, sources B-roll and images, adds music and sound effects, and animates overlays. If captions alone are what you need, the Submagic comparison covers that trade-off honestly.
What does it cost?
There is no subscription and no account. The app is open source, and you bring your own AI provider key and pay those providers directly for the generation work, with no markup from us.
