What it is
Cardboard calls itself "an agentic AI video editor in your browser and on your Mac". In plain terms, an agentic editor is one where you write what you want ("cut the pauses, add captions, make it vertical") and the software makes the edits itself, instead of you dragging clips along a timeline. The company is a small team in Bengaluru from Y Combinator's Winter 2026 batch, according to its YC company profile.
The browser version has been around for a while. Cardboard announced the Mac app in its changelog on 28 September 2026, and it launched on Product Hunt on 9 November 2026, where it finished tenth. The Mac app changes three things. Your footage is processed on your own computer, so you skip the upload. The Lite plan is free inside the app. And you can plug in the Claude or ChatGPT subscription you already pay for to drive the edits.
This matters if video is something you know you should make but keep putting off. The slow part for most small operators is the editing: trimming the ums, adding captions, cutting a 9:16 version for social. A tool that does those jobs from a short written brief removes the main excuse.
Who it's for
Cardboard fits people who need a steady stream of short, simple videos and have no wish to learn a timeline editor. Think of a solo founder recording product walkthroughs, a coach turning a webinar into clips, a café owner making a weekly promo, or a creator who films talking-head videos and needs captions and vertical cuts.
It suits you less if you already edit comfortably in Final Cut or Premiere, if your work depends on precise colour and sound, or if you are on Windows or an Intel Mac. The Mac app needs Apple Silicon (M1 or later); everyone else uses the browser version, where editing and exporting run in the cloud.
What it actually does
According to its site, Cardboard handles the routine edits most small-business video needs:
Cleanup and captions. It cuts pauses and filler, adds captions, and reframes footage, including to 9:16 for vertical video.
Motion graphics from a prompt. You describe a title card or lower third and it builds one.
Edits from a reference. You paste a link to a video you like and ask it to match the pacing, style or colour.
Generation. Paid plans add AI-generated video, images, music and sound effects, plus voice cloning on the higher tiers.
Handover. It exports MP4 or MOV up to 4K, or sends the timeline to Premiere Pro, Final Cut Pro or DaVinci Resolve if you want to finish by hand.
The privacy point needs care. Cardboard's Mac page says "files are processed locally, so there's nothing to upload" before you start editing. The same page adds the detail: "only what the AI needs to make your edit (frames and the transcript) is sent" to process it, and to your own agent if you connect one. So your full video files stay local, but samples of them do leave your machine. If you film anything confidential, such as client calls or internal numbers, factor that in.
The bring-your-own-agent feature means you can direct Cardboard from Claude or ChatGPT instead of its built-in assistant. The Mac page says this "requires an eligible paid Claude or ChatGPT plan" and is set up under Settings, then Agents, with no API keys and no terminal. If you already pay for one of those assistants, you keep working in a chat you know. We have not tested the agent connection hands-on, so treat it as a promising extra until you have tried it on your own footage.
Pricing (as of 12 Nov 2026)
All prices below come from Cardboard's pricing page, captured on 12 November 2026. Each paid plan has a cheaper first month, after which the regular monthly price applies.
Plan | First month | Then per month | What you get |
|---|---|---|---|
$5 (free in the Mac app) | $8 | 3 exports at 1080p, watermarked, no generative credits | |
$9 | $29 | Unlimited 1080p exports, no watermark, 400 generative credits | |
$30 | $59 | 4K, voice cloning, premium models, 1,500 generative credits | |
$89 | $175 | All models, priority processing, 5,000 generative credits |
The page also offers annual billing and says you can "save up to 61%", but it does not list annual prices, so we cannot tell you what a year costs on that option.
What this means for your budget: the first-month price is a discount, and the regular price is roughly double. On monthly billing at list prices, a year of Starter works out to $9 plus 11 months at $29, or $328. A year of Creator is $30 plus 11 at $59, or $679 (our arithmetic, before any tax). Budget on the regular price, not the first month. Note too that free Lite on the Mac comes with usage credits once, not monthly, so it is a trial rather than a permanent free tier.
Getting started
The idea is to judge Cardboard on one real job before you pay for anything.
Download the Mac app from the Cardboard for Mac page and sign in. No card is needed for Lite.
Pick one real clip, not a demo: a 3 to 6 minute talking-head video you would actually post.
Write a short brief. For example: "Cut this to a 60-second vertical clip for Instagram. Remove pauses and filler words. Add bold captions. Open on the line about pricing. Add a title card with my business name."
Review and revise in chat. Ask for one change at a time, such as "tighten the opening" or "make the captions smaller".
Export once and watch it on your phone. Remember you only have three free exports, so spend them on finished versions.
Then apply a plain decision rule. If the result needed fewer than five revision requests and you would post it with small fixes, upgrading to Starter is likely worth it. If you spent longer correcting it than you would have spent editing yourself, stop there.
Alternatives
Riverside Agents. Pick this if you record podcasts or interviews and want help with prep, editing, clipping and promotion in one place.
Descript. Pick this if you want more control than a chat window gives you. Descript says it lets you "edit video by editing a doc", so you trim footage by deleting words from the transcript. It has a free plan, and its pricing page lists paid plans from $16 a month (as of 12 Nov 2026).
Jockey. Pick this if your raw material is a large phone video library and you mainly want help finding and assembling the right moments through Claude or ChatGPT.
Limitations
Mac-only for local editing. The Mac app needs Apple Silicon. Windows and Intel Mac users get the browser version, which uploads footage to the cloud.
Prices roughly double after month one. Plan your budget on the regular monthly price.
The free plan is narrow. Three watermarked 1080p exports and a one-off allowance of usage credits.
Local means mostly local. Frames and transcripts still go to the AI to process each edit.
Credits are hard to predict. The pricing page splits usage credits (edits, captions, analysis) from generative credits (AI video, images, music), and it is not obvious how far each one stretches until you use it.
Verdict
Cardboard is good for solo creators who need quick edits, such as talking-head clips, captions and short promos, and do not want to learn a timeline. Start with the free Lite plan in the Mac app and judge it on one real video. The catch is that it is Mac-only for the local app, and the first-month promo prices roughly double after month one, so budget for the regular price before you commit.
