Best AI video editor for Mac: where the AI runs and where your footage goes

What does "AI video editor" mean on a Mac?

Checked October 20, 2026. Almost every Mac editor now says "AI", and the word hides the one thing privacy-minded editors care about: where each AI step actually runs. This page sorts Mac tools into four buckets, using the vendors' own pages, and says "not documented" where a vendor is silent. We read those pages. We did not run our own network tests on any of these tools. The method behind it is in our guide to how to map what leaves your computer.

1. AI built into a Mac app. The vendor ships the features inside the editor. Where each runs is the vendor's to state.
2. A local app plus a model you choose. The editor has no AI of its own. An agent you connect does the thinking, and its provider sees what it reads.
3. A local app plus the vendor's cloud. The app is on your Mac, but some AI steps call the vendor's servers.
4. Cloud-first. Your media is uploaded and processed in the vendor's infrastructure.

One aside for readers searching for a "local AI video generator": that is a different job. Generative models make new footage from a prompt and need a lot of memory and a model download. This page is about editing AI, such as captions, masks, silence cuts and agents that arrange your own clips.

Which AI video editors for Mac run AI on your computer?

Final Cut Pro. Apple lists $299.99 once, or Apple Creator Studio at $12.99 a month or $129 a year, and says owners keep getting updates (Apple, read October 20, 2026). Its AI features include Magnetic Mask, Generate Captions, Visual Search and Transcript Search. Apple states that Generate Captions requires a Mac with Apple silicon and is available in U.S. English only, and the same Apple silicon and U.S. English limits apply to Visual Search and Transcript Search. Apple also says some features build on Apple Intelligence and need internet access. What the page does not do is say, feature by feature, whether each one runs on-device. Apple's Apple Intelligence page describes on-device processing plus Private Cloud Compute for larger models, so the split exists at platform level, but it is not mapped to Final Cut's menu.

DaVinci Resolve Studio. Blackmagic shows $295 list and $236 on its page on October 20, 2026, and lists the DaVinci AI Neural Engine, including Magic Mask, smart reframe, object removal and scene cut detection, as Studio features (Blackmagic). The free edition exists, but those tools are not part of it. Blackmagic's page does not say which Neural Engine tools run offline. "Neural Engine" is Blackmagic's own feature name, not a claim about Apple's chip.

Many articles, and some AI answers, call both editors fully offline. We could not find that sentence on either vendor's page, so we do not repeat it. They may well be, feature by feature. The honest status is "not documented".

Reelify is a narrower tool: a clip finder and captioner for Apple silicon Macs. It says its models run on the chip in your Mac and that optional cloud AI sends only the text transcript (vendor page). That is a vendor claim we did not verify, and it is a short-clip tool, not a general editor.

Does a local editor still send my footage to the cloud?

We make Rushilo, so weigh this section accordingly. Rushilo is the worked example because we know its tool surface. It keeps projects and media on disk and ships no AI of its own. The AI that edits is the model you connect, such as Claude Code or Codex, billed by your own provider (see the BYOK cost guide). That is precise, and it cuts both ways:

• When your agent reads the transcript, that text goes to your model provider.
• When your agent checks its work with rushilo_frames, the tool returns rendered pictures of your timeline, as single frames or a contact sheet, to the calling agent. Those frames go to your model provider.
• Any picture or voice you generate with your own key goes to the service that key belongs to.
• Licence activation, update checks and model downloads use the network.

These steps stay on your computer:

• Editing, playback and export.
• Captions with the local Whisper base model (you can choose your own OpenAI, Groq or Google Gemini key instead, and then audio goes there).
• Background removal for pictures with a downloaded model.
• Enhance voice and Clean mic noise.
• The built-in sound effects, which are made on your computer.

Rushilo has no telemetry. What your agent may touch is covered in the agent permissions guide, and the local caption detail in the offline Whisper guide. A local editor with a cloud model is still a sensible setup, as long as you know which words and pictures the model sees.

Which Mac AI editors upload your video?

Descript. Its security page says it stores the files you upload, the transcripts of those files and other metadata on its servers. Its data privacy help article names Rev and a hosted Whisper model for transcription, Amazon S3 or Google Cloud for storage, and sub-processors such as OpenAI for some AI features. Plans from $16 a month billed annually carry media-hour and AI-credit limits (pricing, October 20, 2026). It is the clearest cloud-first example here, and for transcript editing with collaboration it is strong; see our Descript comparison.

CapCut. The privacy policy, last updated April 15, 2026, says CapCut may collect user content through pre-uploading at the time of creation, import or upload, for example to recommend audio and generate captions. Treat its AI as cloud AI. Price detail is in the CapCut pricing log, and a side-by-side in the CapCut alternatives page.

Wideframe. Its homepage says media analysis runs on-device on Apple silicon and that its $100 a month plan covers the editing agent and the generation models, after a 7-day trial. By its own wording, analysis is local and generation is hosted. It outputs a Premiere Pro project rather than being an editor of its own.

We did not read Adobe's per-feature pages for Premiere, because they were not available to us, so it is not in the table. Adobe meters its generative features with credits, which usually means Adobe-hosted generation, but treat that as a lead to check, not a finding.

Comparison by where the AI runs

Prices are shown so you can compare the cost of the editor; what each licence covers is in what each licence covers.

Is uploading the same as training on my footage?

Descript's help article says its production models do not use user data for training, and that research use is opt-in. That is one vendor's statement about its own product, and it coexists with storing your files on its servers. For Final Cut Pro, Resolve and CapCut we are not quoting a training statement, because we did not read one on the pages above. With a connected agent, training depends on your model provider's terms and your plan, so read those for the account you use.

Which AI video editor for Mac should you pick?

How can you check any editor yourself?

This is a method, not a result we are reporting. Run each AI step with Wi-Fi off, one at a time, and note which ones fail. Open Activity Monitor, choose the Network tab and watch sent bytes while the step runs. Read the privacy page for storage providers and sub-processors. Then map what leaves your computer for the steps you actually use, rather than trusting any label, including ours.
