Local AI runs a specific task—such as transcribing audio or summarizing text—on your device rather than sending that task’s content to a remote model. That does not automatically keep every copy of a note local: sync, backups, diagnostics, sharing, and more complex requests may use separate cloud services.
What “local AI” means when it handles a note
A local AI workflow has three parts: the content (typed text, audio, or a captured screen), software that recognizes or generates language, and the hardware that runs it. Depending on the task, processing may use a device’s CPU, GPU, or neural processing unit (NPU). Compact models are designed to work within a phone or PC’s limits on memory, power, and speed.

For a voice note, one component may convert speech into text; another may summarize or rewrite that text. Those are separate operations, and they do not have to use the same processing path. Ask where recording, transcription, summarization, search, and follow-up questions each run.
Local processing is not the same as “nothing ever goes online”
“On-device” describes where a particular operation runs. It does not, by itself, establish how an app syncs notes across devices, backs them up, handles diagnostics, or shares content. Nor does it rule out a cloud fallback for requests that need more computing power. Check those data flows and settings separately.

A cloud service can have privacy safeguards and still be cloud processing. The relevant question is not only whether a provider says data is protected, but also whether the task’s content leaves the device and what the service says happens to it.
How the documented Apple and Windows examples differ
| Feature | Documented processing path | Controls and qualifications |
|---|---|---|
| Apple on-device dictation | Apple says dictation processing happens completely offline. Apple’s privacy features | This describes dictation, not every Siri, Spotlight, Safari, notes, or Apple Intelligence function. |
| Apple Intelligence | Apple says it primarily uses on-device processing. More complex requests may use Private Cloud Compute, where relevant request data is processed on Apple silicon servers. Apple Intelligence and privacy on iPhone | Apple says requests sent to Private Cloud Compute are not stored, and its security guide describes the system’s protections. An on-device report shows requests from the last 15 minutes by default, or up to seven days. Availability varies by device, language, and region. Private Cloud Compute Security Guide |
| Windows Recall | Microsoft says Recall snapshots are stored and analyzed locally; an internet or cloud connection is not required for saving and analysis. Manage Recall for Windows clients | Saving is opt-in. Users can pause or disable it, filter apps and websites, and delete snapshots. Microsoft also notes that diagnostic data depends on privacy settings. |
| Phi Silica on Copilot+ PCs | Microsoft describes Phi Silica as an on-device language model for tasks including summarization and rewriting on supported Copilot+ PC hardware. Windows Copilot+ AI components | This operating-system capability does not prove that a particular third-party notes app uses it, or that every operation in that app is local. |
| Microsoft Copilot Record | After recording stops, Microsoft says audio is uploaded to OneDrive and processed within Microsoft 365 service boundaries. Get started with Record in Microsoft Copilot | This is a cloud workflow, even though Microsoft describes service boundaries and related protections. |
Apple: local work with a possible cloud route
Apple describes Apple Intelligence as primarily on-device, while allowing Private Cloud Compute for more complex requests. Apple says relevant data is processed on its servers and removed afterward; the company also says independent researchers can inspect the server software. These are Apple’s stated design and security claims, not a guarantee that every feature on an Apple device follows the same route.

Apple separately documents offline on-device dictation. Its privacy information also describes some Siri and Spotlight/Safari activity that can involve servers, as well as certain encrypted information used to improve recognition. Treat each feature separately rather than inferring a blanket privacy rule for all notes or requests.

Recall captures snapshots so users can find things they have seen on a qualifying PC. Microsoft says snapshots are encrypted and protected using Windows Hello Enhanced Sign-in Security and TPM-related controls. Enabling snapshot saving requires user choice and authentication. Saving pauses automatically if available storage falls below 25 GB.

Microsoft lists these minimum Recall requirements: a Copilot+ PC, a 40-TOPS NPU, 16 GB of RAM, eight logical processors, 256 GB of storage, and 50 GB free to enable the feature. Recall is disabled and removed by default on commercially managed devices, according to Microsoft. Requirements and availability can change, so check Microsoft’s current documentation for the device and Windows version in question.
Phi Silica, by contrast, is a language-model capability for supported Copilot+ PCs. Microsoft lists text understanding, summarization, rewriting, and short-form generation among its uses. Its presence in Windows does not establish which model a note-taking app calls or whether the app’s other functions communicate with a server.

A practical checklist for checking a notes workflow
- List each step. Identify where audio capture, speech-to-text, summarizing, rewriting, search, and follow-up prompts are processed. Do not assume one “AI” switch covers all of them.
- Look for cloud fallback. Check whether complex requests can be sent to a provider’s servers, and whether the app explains what content is sent, retained, or deleted.
- Inspect separate data flows. Review sync, backup, diagnostics, and sharing settings independently of the AI feature’s processing location.
- Check controls and eligibility. Confirm whether the feature is opt-in, how to pause or disable it, whether you can delete its stored data or exclude apps, and whether your hardware, operating system, language, region, or managed-device policy is supported.
- Use offline behavior as a limited check. If appropriate, try the feature with the device offline. A task that works without a connection may indicate a local path for that operation; it does not prove that all app functions are local or establish what happens when connectivity returns.
